Ford - Explorer :: 1991 XLT Won't Start - CEL Is On

1991 Ford Explorer XLT, 4X4, 4.0L push-rod motor, 315,000K

Problem Part 1: Excessive fuel consumption

Codes for O2 sensor, system lean, some black smoke, unburnt fuel smell, some slight hesitation when accelerating from a stop

I replaced the 02 sensor, replaced the IAC, cleaned the MAF, replaced the coil pack, replaced the plugs, replaced the plug wires, replaced fuel filter, replaced air cleaner, replaced the PVC valve changed brand of fuel, checked tires and "brake binding" - NOTHING. Truck ran "fine" other than excessive fuel consumption. I decided to replace the fuel pressure regulator and before I could get to the parts store we have...

Problem Part 2:

Truck begins to lope along like there is one bad cylinder. It sometimes "fixes" then comes back (all this over a period of 3 days).

Day 4 it's dead - no start.

The motor cranks, the fuel pump "pumps" 3-5 secs KOEO fuel line is clear, return line is clear, filter is clear. There is fuel at the Schrader valve (do not know pressures) and the electrical system seems OK (sparks to all 6cyl). I believe the crank position indicator is OK because the CEL is on KOEO but goes out when cranking. I have no codes because I needed to remove the battery to re-charge. Fuel pump fuse is OK.

Only other information that may (or may not) be relevant is that lately it is slow to heat up. It does not come off "cold" (for the last 4 days). Maybe it's the thermostat or temperature sending unit? Maybe it's because its -30C here. It heats up fine if I block the airflow across the radiator (the old carboard solution).

I have not checked the relay. Where this unit is on the 1991? Don't say fuel pump.

Ford :: 1992 Taurus LX Sometimes Does Not Want To Start

I have replaced the battery, spark plugs and wires and also replaced the starter in the last 8 months. also I have replaced some fuses and the fuel filter and changed the oil. My car won't start sometimes. it cranks but will not turn over. The fuel pressure is good and it sounds like it is firing but it will not start. Sometimes it will start right up after a try or two.

Also wanted to mention that when we replaced the battery less than a month ago, we bought some ethanol for fuel system and bought some starter fluid to put into it. once we did all this, it ran GREAT for about 2 and a half weeks. it started up every time on the first try. Then a few days ago it started doing what it use to do, start when it wanted to and not a minute sooner.

Ford - Taurus :: Won't Start Easily

192,852 miles. I pushed down on the wiring harness when reattaching the (now) somewhat shorter "H" hose. Thought this could be a problem, so I then ran the "H" hose UNDER the harness (which seemed better). Any chance I could've broken a wire in the harness? I didn't move it very much at all, but those wires have been drying out for 13 years now. The car started right up afterward repairing the hose, but suddenly stopped after idling for about 5-7 minutes ... then it wouldn't start again for at least 15 minutes when it "caught" and idled for about 1 minute. Hasn't started again since. Besides the usual P0430 and P1131 codes, I noticed two other codes: P1744 and P0340.

Don't know if they just showed up today or if they've been there a while. My guess is it's the latter because I once saw P1744 about 7+ years ago and it was due to the cooling system not cooling the tranny fluid sufficiently (which is what has been happening again lately with the coolant leaking out of the "H" hose ... and the Degas tank before that). Temp gauge has been running past mid-scale at idle ... an indication of low fluid, and I've been filling as needed to prevent overheating until this weekend when I finally installed a new "T" on the "H" hose (it was leaking at the molded "T"). P0340 I saw pop up about a year ago during very cold weather. I wouldn't doubt that the damn magnet on the sensor has once again fallen into the synchro like it did 8+ years ago, but would this cause a no-start condition? I wouldn't think so... The car cranks plenty strong. Just won't "catch" and start. Up until today and the hose job, it had been running fine. Even drove it this morning about 10 miles. Could I have a coincidental fuel pump failure? Seems TOO coincidental, doesn't it?

Ford - Taurus :: Won't Start Intermittently

My parents' car is a '99 Ford Taurus. The first time they go to start it in the morning, it either won't start or has some trouble starting. If it doesn't start, they can go back out a little later and it starts fine. Either way, once it does start, it runs fine for the rest of the day, and can be started with no trouble at all. Then the next morning the cycle begins again. It's been to the mechanic twice for this problem, but he can find nothing wrong with it. Btw, this problem has been happening in May and June, so cold weather is not responsible, it has been warm.

Ford :: 1997 Taurus GL Refuses To Start

My Taurus has developed a problem where it refuses to start. When I try to start it, it just cranks over and over and over. I keep trying till the battery starts getting weak. I charge up the battery and then try it again with no luck. A neighbor suggested I get a piece of lumber and gently pound on the gas tank suggesting it might be a stuck fuel pump problem [whatever that means!]. Actually it worked once but after I drove the car all day doing errands the next morning was the same problem. That was three weeks ago.

Ford Aerostar :: 1991 - Cranks No Start / Engine Won't Even Pop

Have a 91 Aerostar that won't start. Has fuel pressure, pulse to fuel injectors, strong spark, strong compression, etc.

Thinking that the spark may be coming at the wrong time I tried a spare ignition module that I keep. No luck. Since my distributor had a lifetime warranty I got another one, again, thinking spark was coming at wrong time. Nothing. Engine won't even pop.

I am going to drop the front pipe in the unlikely even that the new converter is plugged or, somewhat more likely, the muffler, but I am leaning toward a computer at this point.. Still don't understand since it is getting spark and gas why engine won't even pop.

Ford :: 2003 Taurus Refused To Start Intermittently

My 2003 Taurus sometimes refuses to start. There's no real pattern: sometimes it's after the car has run for a while and other times not. Sometimes the starter clicks, other times the engine lights come on with no sound at all from starter/engine. Thing is, the car always ends up starting if I let it sit long enough (15 minutes--several hours). I've read around on the internet and realize this seems to be a problem experienced by many owners. I've changed the battery, checked all the connections, cleaned the starter connections and the Mass Air Flow Sensor. If the starter was bad, it seems like it wouldn't start at all, right?

Ford - Taurus :: Dashboard Lights Come On But Car Does Not Start When Turn The Key

This has been driving me crazy for the past 3 years. My car has 276,000 miles and runs great with no hesitation. I drive this car 1/2 the year and my 2012 Nissan Altima the rest of the year. I alternate every other month so neither car sits for too long.

My problem is most of the time the 2003 FORD TAURUS starts right up. However, sometimes, about 1 out of 5 times or so of starting, when I turn the key, I get nothing. The dash board lights come on, but the car does not start. So I found that after turning the key back and forth from ON to ACC (with nothing) and then turning the key back and forth (left to right and back) after doing that 6 or 7 times, the car finally starts .

Then it runs fine, starts the next 5 or 6 times with no problem. Then I turn the key to start it again, then nothing. So I turn the key back and forth 6 or 7 times and it starts. I took it to the Ford dealer and they said I need a starter. I went out and bought a starter and had Pep Boys install the starter (total price was around 1/3 the price quoted from FORD dealer). By the way, Pep Boys also said a new starter will fix this.

Then 3 months later, same problem. I took it back to Pep Boys and they said most likely the starter is defective. So I got the starter replaced, and all was great for another 3 months. Then the same problem. So I took it to NTB and NTB said it was also the starter. So I had them install a brand new starter.

All was Ok. My battery is brand new and my alternator is ok, used but OK.

Then 6 months later, the same problem. So a friend of mine tried to fix it. He unplugged the battery over nite, and had my re plug the battery cables to the battery terminals the next morning. And all was fine for 4 months. Then the same problem again. This time it took about 14 or 15 key turns before the car finally started. (Note: after 8 turns of the key back and forth, it resets the key FOB for programming on the Ford Taurus). This guy checked my electrical and cable from the starter to the battery, and he said all was Ok. He then tried to start the car, turned the key, and it started right up.

I don't mind turning the key back and forth, but if someone is in the car with me with the summer Atlanta heat and humidity, it can be a little uncomfortable, until the car finally starts. Keep in mind, the car always starts eventually. The car has never let me Down. I got the car in 2007 and the car still runs great and the A.C. blows super cold, no funny smells inside the car and the transmission is good. I like this car. I think it is built Much better than the 2012 Nissan Altima.

Ford - Taurus :: Run For Long Period Of Time And Then Won't Start

The problem I'm having with this vehicle is that, it will start up just fine most of the time if I just hop in my after and haven't drove it for a while, however after I drive lets say 20 min+ and then decide to turn the car off and go back to turn it on, it just wont, it will turn over and its getting power but it won't follow through to start the engine, took it to a place by my house for 3 days and they said its probably the fuel filter but they couldn't give me a straight answer, what it most likely is? Its a 2001 Ford Taurus...

Ford - Taurus :: 2003 - Won't Start Easily Hesitates?

2003 Ford Taurus, 49k miles, 3.0 OHV V6 (Vulcan).

It's my daughter's car, she's away at college, so it only gets driven once a week at the most. For the last year or so when I turn the key to start, the starter starts to turn, hesitates for a second, and then turns over and starts the car. I've been assuming the battery was a little run down from sitting so much. There are no noises, clicking or grinding, just this slight hesitation. The battery terminals are clean.

Last night it wouldn't start on the first try, I had to turn the key 2 to 3 times before the starter would turn the engine over. I took the battery to Advance Auto and it tested fine but needs a charge (~12.2V). I'm slow charging the battery with a Battery Tender so it's going to take a while.

This hesitation, is it a sign of a failing starter?

Ford - Taurus :: 2002 - Overheated And Engine Won't Start

I drove 10 hours in my 02 Ford Taurus perfectly fine then a day later New Year's Day car didn't start for some reason I took it to the shop turns out I needed a new alternator, battery, new belt, made sure all wiring was good, and topped off all fluids (which were very low) ...... After that everything was fine for awhile then in the evening I drove bout 36-40 mins turns out my fan wasn't on the whole drive and car started smoking bad (white smoke) when I got to a parking garage popped the hood water was trying to burst out of its compartment in a panic.

I opened the dam thing shit spewed everywhere and burned my arm we let the car cool down started it again added water to the tank where it was lost everything seemed ok then not too long later I was getting off the highways car starts smoking yet again but this time the engine literally stop working I pull over looked under the hood white smoke is now coming from engine and when I try to restart it it's starts and died couple seconds later and from the looks of it I was leaking some fluid as I was getting off the highway and still was leaking something when I pulled over. I just got smacked for the alternator earlier in the day and now all this happens and I'm so confused ...

Ford Ranger / B-Series :: 1991 - Won't Start But Crank Great?

Getting the Banana ready for it's smog test appt at the shop last night (it WAS today) Check engine light had popped on and it had been starting to sputter and surge at the idle occasionally for the last few days so I took a look at the MAF and saw dirty wires. Aha I can fix that, a couple squirts of MAF cleaner, plug it back in and voila! No more light, the Banana ran down the road around the block, over the hill and through the dale like a champ. I shut her down and call it a night.

This morning, hop in and fire the Banana up like usual and all I get is a nice peppy crank over. The Banana has had a bunch (pun intended) of new parts throw at her recently... new battery, starter solenoid, plugs and fuel pump relay and fuel filter. All within the last couple of months.

Out of complete disbelief, I ground on the ignition for a little while and she finally kicked over and sputtered to life. I let her idle a couple of minutes and things seemed fine so off we go. I make it about a block before the Banana starts hiccuping and bucking like something possessed and dies.... kaput.

The Banana has a 3.0, manual transmission and at least half a tank of fuel. Long story short and a tow truck ride home again, half a day trying unsuccessfully to pull a code, any code.... nothing. She will half-heartedly cough and spastically run with ether shots and near as I can tell I'm not getting fuel to the fuel rail relief port. I'm really hoping there is some way to diagnose a faulty fuel pump without having to drop the tank and fish the damn thing out.

I'm not hearing it run when the ignition is turned on but then again I don't think I've ever heard it run. Any other things to try before I replace the pump itself???

Ford Ranger / B-Series :: 1991 - Take Very Long Time To Start?

Grandson 1991 Ranger 3.0 v6 69,000 miles We have a long start issue after it has sat for 30 mins. plus. If you open the throttle part way while cranking it will start fairly easily. Fuel pressure comes up instantly when you turn on the key. It runs at 39 psi pull the vac line off regulator it jumps to 49 psi. Fuel pressure does drop to about 30 psi after setting an hour. It kinda acts like it is flooded when it starts. so far we have done a complete tune up plugs wires cap and rotor. The ignition module has been replaced twice last one a real Motorcraft. New fuel pump and filter. Cleaned the fuel injectors with Ford cleaning system. I will replace the coil next and maybe clean the iac.

Ford - Taurus :: 1997 SHO Engine Failed To Start When Turn The Key

My daughter has a 1997 Taurus SHO and it's been running pretty well until this morning when a turn of the key failed to start the engine. The battery is fully charged but when she turns the key, we get the click from several places under the hood, including the starter relay. I'm pretty sure it's the starter relay, it's inside of the fuse box, is identified as "starter" on the guide printed inside of the cover and is black plastic about 1.5 inches square. The windows, radio, horn and all of the other accessories work, but no reaction to the key.

Ford - Taurus :: 2001 - Electrical Malfunction - Won't Start Up Immediately?

Car has been having a myriad of problems that seem to be related to the electrical system. First warning sign that something was wrong was the car wouldn't start up immediately after turning the car off. We had to wait between 5 and 20 minutes before the car would start up again. It was also revving up briefly at idle. Brought it into the mechanic, they replaced the power steering pump. We told them about the issues with turning the car on, they said they didn't see anything.

Car worked fine for a couple of weeks, then when we were driving a longer distance (more than an hour drive) the tire pressure alert light went on. We were close to our destination, so we drove and parked, and the tire pressure was a little low. We were asked to move the car to a different spot in this lot, and it wouldn't turn on. When we came back to the car (this was after flying out of down for four days) the car started up fine, and we filled the tires with air.

Next time we went on a longer drive, the tire pressure alert light went on again, but we checked the pressure and the tires were fine. This light turning on issue has continued, without seeming to be related to the tires actually losing pressure at all.

A couple of other problems that may be related. One, the car completely stalled out once at an intersection, and the battery warning light went on. I turned the car off, waited 60 seconds, then turned it on again and drove home just fine. Also, the right turn signal is flashing at double speed on the dashboard, but there aren't any issues with the headlights or taillights themselves that would cause the light to flash at double speed. The left turn signal and the light on the dash flash normally.

I'm worried that this may be indicative of a larger problem in the electrical system, and since the mechanic told us the first time that they didn't see any issues I wanted to get a second opinion before I brought the car in again. I also don't really have a lot of money to spend, so I need to know if this is a critical issue or just something I can ignore until I get a new car early next year.
