Ford Ranger / B-Series :: 1990 - Broken Fuel Line At Fuel Pressure Regulator?
I have a 1990 Ranger with a 4.0L that I just changer the intake gasket on. I broke the fuel line at the Fuel Pressure Regulator. Cant seem to find one anywhere. It is a nylon inside/rubber outside with a cloth mesh and quick connect fitting line. Where to get one? Can I hose clamp it the FPR by cutting off the connector that broke?

I have a 1999 Ford Ranger and every morning when I go out to start it, it really hesitates and doesn't want to run for a few minutes. once it's going it's fine I can shut it right off and it starts fine, and I can leave it all day from 9am to 6pm and start it again at 6pm and it doesn't hesitate, it fires right up.. it seems like it only happens over night..
When I hooked the code reader up, I get codes P0171 (too lean bank one) & P0174 (too lean bank two)
I also get for the I/M readiness status, that the
EVAP - NOT RDY,
O2S - NOT RDY,
HO2S - NOT RDY
Just want to say also that the shop I had put 2 oxygen sensors in not long ago.=
Ford Ranger / B-Series :: 1990 Truck Won't / Hard Start When Cold
My 1990 4.0 refuses to start when the air temperature outside is at approx 40 degrees or below. It will crank until the battery runs dead if I let it. At approx 50 degrees farenheit the truck takes forever to start and always backfires out of the tailpipe and intake manifold (blowing off a hose on the vacuum tree) before it starts. If I can get it to backfire, it will start eventually. If it does not backfire, then I can run the battery dead and the truck still refuses to start. This condition has grown from a little problem to a huge problem over the past 6 months. Here is what I have done so far, including regular maintenance items.......
KOEO test checked OK
KOER test returned code 77 multiple times (TPS).
Replaced Throttle pos. sensor
Replace Idle air bypass valve
Subsequent KOER test came back with no more codes except 11 - OK
Load tested battery
Made new heavy gauge battery cables for + and -
New plugs, wires
newer starter
Changed coil pack for known good one off my explorer
Visually inspected hoses for vacuum leaks, replaced 1 cracked hose

Ford Ranger / B-Series :: 1990 - Rough Start - Running Lean?
]I recently bought a 1990 ford ranger with a 2.9 @187,000 miles. That being said I went through and changed a few vacuum lines, the oil, air filter, pcv/grommet, and fuel filter.
The problem is it hates to start. I could crank on it for 10 seconds and not a single thing. Sometimes if i turn the key to the off position, wait a second, and try again, Ill get the truck to fire. When it does fire up it just reeks of the lean exhaust. It also gives me some hesitation when I rev it. I did a fuel pressure test (KOEO) last night and it gave me 32 psi and within a minute the needle fell to about 25 psi. I hear the fuel pump run for only 2-3 seconds too.
I've already pulled the MAF off and cleaned it, replaced the TPS, and did a fuel pressure test. The fuel filter is brand new
Ford Ranger / B-Series :: 1994 - Hesitates Under Acceleration
Having a slight issue with my ranger. So I bought this truck out of a junkyard about a month ago, its a 94 4x4 with a 4.0 and a five speed. When I bought the truck the motor was blown so a few weeks ago i replaced it with a 4.0 from an aerostar van I had laying around. Right after I changed it the truck was running good with no issues, until a few days ago going to work the truck started hesitating going up a hill. Now the truck does it all the time, sitting at idle the truck runs smooth as silk, at half throttle it does it the worst but when you mash the peddle to the floor it clears up and runs good.
So far I've replaced the plugs, wires, coil pack, mass air sensor, throttle position sensor, and the fuel pressure regulator to try and fix it but nothing has worked. I've checked the fuel pressure it has 30 at idle and 40 with the vacuum hose pulled off of the regulator, I even taped the gauge to the windshield and went for a ride and there was no drop in pressure when it started acting up. a few other things i have done were plugged all the vacuum ports to rule out a leak, reset the computer and checked for codes. the only code that came up was 522. So I think my next step is going to be buy new oxygen sensors ? But my question is wouldn't the check engine light come on if it was an oxygen sensor ?
Ford Ranger / B-Series :: 1995 - Would Not Start / No Fuel Pressure
I have a 95 Ranger 2.3 with a manual tranny. In the past I have had problems with this truck not starting do to a bad inertia switch and numerous fuel pumps. A couple of weeks ago I pulled the truck off of the driveway into the street and let it set there for a few hours. When I went to put it back on the driveway it would not start. I got it pushed on the side of the garage. I did my normal routine of doing a pressure check. I had no fuel pressure so I assumed that it was the fuel pump (as usual) so I dropped the tank and changed the pump.
I got it back together and it still wouldn't start. I checked the fuel pressure and the manifold still had 0. So I started my diagnostic. I have power from the fuse to the fuel pump relay. I then checked the wiring at the inertia switch and found that there is no voltage with the key on at the supply side of the inertia wiring. I verified continuity between power distribution block and the inertia switch. I put in a new fuel pump relay and it still has no fuel rail pressure and there still is no electric signal at the inertia switch. Where to go from here?
Ford Ranger / B-Series :: 2001 - No Fuel Pressure At Start
2001 Ranger, 108,000 miles, good regular maintenance per the Ford Schedule. 4.0L manual trans.
I changed the fuel filter 20,000 miles ago. This has been a recurring issue anytime my fuel level was low, about 1/4 tank or less, and when the truck was warmed up, hot. The fix in the past was to add fuel and let the truck sit for awhile. Now, today I drove home for lunch and when I tried to start the truck to return to work, it wouldn't start.
Same conditions, low fuel level and it was warmed up. The engine will turn over and start to run with ether in the air box, so it's definitely fuel related. A fuel pressure gauge on the Schrader valve got a zero reading, not even a flicker, and no residual pressure after shut off.
Could this be only a fuel pressure regulator issue? Or should I prepare to replace the fuel pump? Is there a fuse that might be blown?
Ford Ranger / B-Series :: 1995 Will Not Start - Fuel Pump Going Out
My 1995 ford ranger with a 3.0 will not start. It acted like the fuel pump was going out so I replaced it. I also replaced cmp sensor and the camshaft synchronizer due to old cmp sensor broke and messed up the synchronizer. My truck is getting fuel and spark but still will not start. Where do i go next?
View 4 RepliesFord Ranger / B-Series :: Engine Hesitates - Got 157 And 158 MAF Sensor Fault?
Problem: engine surging/hesitation, from idle to highway speeds. It will start and run fine, just hesitates/surges when gas is applied.
Before I pulled the codes, I tried seafoam in the gas tank, cleaned MAF sensor, cleaned throttle body, checked air filter, changed fuel filter, pulled/cleaned plugs, nothing worked.
Then today I finally used a scanner and pulled codes (my CEL doesn't work) and I got 157 and 158 MAF sensor fault, high and low voltage. I am reading about 6v on the C and D terminals of the MAF, I know that is much higher than normal, but what does that tell me? Why both high and low voltage readings? Just a bad sensor, or wherever that voltage comes from, ECM?
I also pulled 189 HEGO H02S sensor fault, unable to switch/lean during part throttle. What does that mean, just a bad O2 sensor?
Last I pulled a 542, fuel pump secondary circuit fault. Does that mean the fuel pump is bad or going bad?
More importantly, what should I troubleshoot first, would any of these codes cause my problem?
Ford Ranger / B-Series :: 2002 - Trans Hesitates - Shakes At 65 - 70 MPH?
02 ranger 4.0 v6 auto has 110000 miles on it. at highway speeds 65-70mph feels like it strugles to shift, truck will shake and bounce some. when this happens rpm's jump from about 2200 to 3000-3200 after a little bouncing rpms drop to normal. issue seems to be the worst going up hill but will happen every time i hit 65-70. Also the truck will not bounce or shake with the OD turned off and seems to run fine this way.
tranny fluid/ filter just replaced with no change. new plugs and wires
Ford Ranger / B-Series :: 1999 - Fuel Pump Won't Turn On At Start Up?
My 1999 4.0L v6 Ranger (auto trans) is having some issues. Recently the fuel pump won't turn on as normal when I turn my key. I have to turn the ignition on and off 10-20 times before I hear the pump kick on and I can start it. I already checked the relay and fuel pump shut-off switch. Neither was the bad.

Sons 94 ranger 4.0 4x4 Auto 185k got him to work yesterday but would not start to bring him home. No spark, checked with timing light, and no fuel pressure. Searched and read alot of tips from Pawpaw so I tried a few things with no luck. Swapped the relays around, inspected coil pack and plugs. CEL was not on and goes out while cranking. I have a OBD scan tool but this truck must be too old or I need finding plug. Crank sensor maybe?
View 7 RepliesFord Ranger / B-Series :: 1988 V6 Won't Start After Fuel Pump Replacement
I have a 1988 Ranger 2.9 V6 that sits most of the time. The fuel pump quit working so I removed the bed and replaced the pump in the tank and the inline filter near the engine. I did not replace the inline high pressure pump because it still made a humming sound so I assumed it is working. Now when I turn the switch on I hear both pumps working but the truck will not start. It seems like it wants to fire or fires for just a second but just wont completely start. Is the system supposed to be primed and if so how?. I suspect a fuel problem but I dont know how to check pressure or check to see if fuel is getting to the engine. What to do next?
View 6 RepliesFord Ranger / B-Series :: 1990 - CEL Only On At Idle
I recently acquired a 4.0 Ranger 4X4 Auto for my use in Costa Rica. It runs fine but it'll illuminate the CEL within a few seconds of starting and whenever revs fall below approx 1000. When pulling off the line or accelerating, the light will go out but comes back on when the throttle closes. The previous owner has replaced the MAF and idle air valve. I've corrected a lot of issues with the vacuum system and think it's back where it ought to be. I know I am going to need to pull the codes but I'm back in Dallas now and can't do it yet. Need general list of affected parts that I could buy here and take back down.
View 14 RepliesFord Ranger / B-Series :: 1990 - Overheating While AC Is On?
I got a 1990 Ranger 4x4 2.9l that loves to get hot only when the ac is on. The engine was rebuilt by me about 2000 miles ago and I made sure to have the block boiled in order to clean out any crap that could've been built up in the water jackets. So far the radiator, cap, thermostat, and fan clutch have been replaced. The fan shroud is intact and the condenser has a few bent fins but not many.
Here in Vegas we're looking at 100+ from 10 am - 4 pm so the ac is a must. I could be sitting at a light all day with the ac turned off and the truck doesn't have an issue. When I turn the ac on though the truck almost immediately begins to get hot. The engine drops maybe 100 rpms and the voltage gauge also drops a little. At night if I'm running the ac the voltage drops to what looks like 10 volts.
While the ac is on there is an immediate loss of power as well. In my head I'm thinking a failing compressor, water pump, and alternator are at fault. It doesn't matter if the truck is moving either, the temp still climbs.I know the rangers are funky with their cooling so when I burped the system i turned the heater on and lifted the front end about 1 ft off the ground with the cap off.
Ford Ranger / B-Series :: 1998 4.0L Cranks But No Start / High Fuel Pressure
Made a trip to the hardware store yesterday. When I came out, the truck would crank just fine, but wouldn't start (98 4.0L 4x4). Tried adding gas, no luck. I had actually called a wrecker, but it eventually started after sitting for about an hour. All I did differently was hit the gas pedal a couple of times. Thinking it may be a low fuel pressure problem, I took it to autozone this morning (started it about 4 times now with no problems). Checked the fuel pressure, and it sat at a solid 65 lbs at idle. I tried holding the throttle open and it stayed at the same pressure. I forgot to try with the vacuum off.
First off, I've seen some people say 60 lbs is right, but more say it should be at about 45lbs. 45 seems right since the fuel return is on the block, not on the pump. I'm guessing the fuel damper went out, but is there any good way to check it? Also, since the damper is vacuum controlled, would a bad vacuum cause this problem? Third, could high fuel pressure cause it to not start? That's the one I'm most worried about what was wrong there.
Ford Ranger / B-Series :: 2000 - Just Turned Over But Would Not Start - No Fuel Pump Noise
My daughter's boyfriend just bought a 2000 ranger with a 2.5. We just put a flexplate in it and it wouldn't start. Just turned over. Listened for the fuel pump and no noise. After a few minutes, it worked. He drove it home last night and said that it didn't want to work first try but worked with the second try. He drove it to church, 40 miles, and it sit for around two hours and wouldn't start, no matter how many tries.
We tried changing the relays around with no luck. We went and eat lunch and back to the truck with a rubber hammer. Then it starts on the second try without using the hammer. We got under it and cleaned the connections up and put some bulb grease on them. I couldn't get the one apart right on top of the pump itself, I was afraid of breaking it. It's been doing fine since we left the church before we cleaned the connections.
Ford Ranger / B-Series :: 1986 - Start Over Fuel - Idles Very Roughly - Stalls Out?
its 1986 Ranger with a 2.9L V6 Auto 4x4, well to start with it seriously over fueling also it idles very roughly and even stalls out sometimes, when I'm trying to hold it at a speed it acts like it is missing (I guess that's from over fueling as well and it also pukes out lots of black smoke, it goes through way too much gas for a V6), but when I speed up fairly hard it acts fine until I try to maintain speed again, I have already put a tune up into it and a new EGR as well a fuel regulator and how to fix it?
