Ford F-150 - 1997-2003 :: 1998 Truck Not Starting / Not Getting Voltage At Fuel Pump
I have a 1998 Ford F150 with 4.2.. Started off a intermittent problem of not starting acct no fuel. Now will not start at all. Checked all fuses and relays.. Am not getting voltage at fuel pump. Changed ECM thinking that was the problem.. Have checked all multi wire connectors for corrosion and tightness. Am at a lost what to try next.
Also, not sure if its related or not. The turn signals and hazard flashers do not work. When I turn on the hazard flashers, nothing happens. If I leave the flashers switch on, the turn signal work. Checked all fuses and relays and they appear good.
Ford - Explorer :: 1995 - Replaced Fuel Pump / Filter / Pressure Regulator / Crank Position Sensor But Won't Start?
1995 Ford Explorer, 4 ltr. engine, pushrod. Will not start. Replaced fuel pump, fuel filter, every relay, pressure regulator, and the crank position sensor. I realize there's a whole bunch more parts under the hood, but I am ready to give up. Before the fuel pump would not run. Reason for replacing the parts. Now it won't stop running and you can feel the fuel by-passing at the pressure regulator. When checking the pressure at the rail I get zero !! I used a tire pressure tester for this. And, like I said no pressure. This vehicle has around 170,000 miles on it.

Drove for 25 miles. Park, try to restart to park truck at other place. Truck start but very rough. Did drive for 20 yards and truck stop. Try to restart no way. I think I do not hear fuel pump when I turn key and gas pedal fill completely empty, no any force to move it. Should I assume fuel pump or should check some sensors first? I have P0420 for a few weeks, not source of this problem. Drove truck before with P0420 for years. No other code. Do we have PATS in keys? My truck is f250 99 LD. My pickup have PATS. How to check it?

I ran out of CNG - truck won't start on reg fuel. Fuse good, relay clicking and I believe I have voltage going to plug connector going to tank. However, I do not have any wiring diagram to know what I'm looking for. The plug is four wire - yellow- 11 volts, red / black stripe 7 volts, black / red stripe and black wire no volts. What checks can I make before dropping the fuel tank and pulling fuel pump? 2003 F150 7700 Bi-fuel ....

1999 4.6L won't start after sitting a month. Ran fine before, now won't start. Cranks fine. Cannot hear fuel pump turn on when key is turned. Fuel pump fuse is good.
Fuel pump relay clicks a few times when key is turned. Is this normal? I am hoping it is the relay and not the pump. What should I check next? The wires at the pump? What should they read?

View 3 RepliesChevrolet - 1500 :: 1997 Chevy Truck V8 Fuel Pump Failure
Several years ago I had to replace the fuel pump - truck had about 100,000 miles. Within the last 4 - 5 months I have replaced the fuel pump twice and just today (about two months since the last replacement), the fuel pump has failed again. That has been the pattern now for the last several months. I have had the work done by one of the reputable car repair shops in town - they have also done work on my 2004 Impala with no issues with the repair. There must be something else going on besides just the fuel pump going bad. What would cause so many fuel pump failures.

01 7.3. Cranks, won't start. Tank was at 1/4 but is full now. The lift pump runs, I can feel and hear that the motor is spinning when I cycle the key. I removed the fuel filter and cycled the key and get no fuel into the bowl. It looks like the lines are stainless from the pump to the tank so I doubt it is sucking air. I pressurized the tank with a shop vac and I get fuel coming into the filter housing. Am I missing something obvious? I have never seen an electric pump that would run and not pump fuel. I removed the suction line at the pump and don't feel any suction there.

View 2 RepliesFord F-150 - 1997-2003 :: 2001 - Fuel Pump Won't Run When Cold
I've got a strange problem on my '01 F-150 4.6L 4X4. When the outside temperature gets below 40-45 degrees the fuel pump won't always run when trying to start the truck. You can cycle the key switch on/off 8-10 times and the fuel pump will run. The engine will then start and run fine. You probably have to use this procedure 80% of the time. It started this last winter. I replaced the fuel pump relay in the power distribution box under the hood but that did not work. When the outside temp warms up the problem goes away.

My brothers 2001 is having an issue with the fuel pump. It has a random no fuel pump basically the fuel pump does not come in, he turns the ignition off then back on and you can then hear the fuel pump turn on and the truck starts and runs normally. I'm not looking forward to dropping the tank to replace the sending unit so I was thinking maybe the relay is the issue? I'd eater do that than a sending unit job...

New to this site, my problem is on my 2003 4.6L fuel pump not working.My problem is that I am not getting voltage to contacts on pcm and fuel pump relays.
Getting volts to #30 fuse 30amps ok, voltage to pcm diode ok. Voltage on #30 on both relays(pcm & fuel) but I am loosing voltage across coils contacts #85 & #86, these makes hot #30 & #87 to make pump work. Inertia sw ok, Don't know if PCM is bad, ck fuse #2 ok 5 amps.
Ford F-150 - 1997-2003 :: 2002 - Stumbles - Hesitates During Acceleration - Fuel Pump?
My 02 F150 4.6 has 84K miles on it, and started stumbling/hesitating during accellartion about three weeks ago. Before this problem started (about 2,000 miles ago), I installed a new fuel filter and air filter. Since I noticed the problem, I installed new plugs. The problem didn't go away, so today I checked the fuel pressure. At idle the pressure is 32psi with the vacuum line left on the fuel pressure regulator (30-45 is normal as per Chilton's), and 42 with the vacuum line off (40-50 is normal as per Chilton's). I also had someone else rev the engine so I could observe, and found that the fuel pressure went as low as 28 when the engine speed was quickly increased. The standing fuel line pressure is 30 (30 is normal as per Chilton's) Does this sound like a fuel pump problem, or is there something else that I'm missing.
View 10 RepliesFord F-150 - 1997-2003 :: 1998 - No Fuel Pump Buzzing Sound When Turn The Key To On Position
Ok I have recently bought a 1998 Ford F-150 V6 4.2L 2WD and when the guy sold it to me the check engine light was on and he told me that randomly when you turn the key to the on position you will not hear the fuel pump buzzing sound and he knew it wouldn't start, he said you would have to turn the key from the on and off position many times until you hear this sound and then the truck will start and run fine.
First off I got the codes read and there were three of them P0171, P0174, and P1537 some things to note are that the drivers air bag looks like it had deployed, the cover is loose and when I pulled it back the air bag looks duct taped up inside there that would cause the air bag light to continuously flash while driving. I noticed the battery leads were corroded so I replaced the battery and put new battery clamps on both wires, after that the problem did not happen for a week and I though it was over but it happened again.
Next is that the truck has the PATS system and it did not come with a remote which I have also read that the PATS system can cause the fuel pump not to turn on but not sure if this would cause it to not start randomly because sometimes it starts right up. When I started to look at the simple things to fix I noticed it did not have an air filter in the housing. so I thought the MAF sensor could be dirty so I cleaned it with the special cleaner, I put sea foam into the intake via a vacuum hose and also have put a fuel system cleaner in a full tank and have driven most of the gas out. After putting in an air filter, cleaning the MAF sensor, and sea foaming the intake, it seems to run a bit better but I am still having the random fuel pump issue.
I have checked the fuses and the and the fuel pump and ECM relays both are fine. Today I put new exhaust on it because it had some bad exhaust leaks and the truck did not start again, so the guy trying to put my exhaust on, hit the fuel tank with a hammer and it didn't work then hit it again and it finally worked. Im not sure if the hitting it did it or if it just randomly turned on like always from turning the key on and off. The new exhaust has made a huge difference in driving it feels and sounds much better.
Also to note is that when I am stopped at stop lights it will idle at about 1500 and then it drops down to 500 and back up and back down again and it does this at most stop lights, and it is not an abrupt drop it just slowly idles down and back up again. Again once the truck is started it runs perfectly fine with no issues, and there are no specific times when it has the problem it seems to be randomly. I know that many people will tell me to change the fuel pump out and I am already prepared for this but if there is any easy things I haven't thought of yet...
