Ford Ranger / B-Series :: 1988 V6 Won't Start After Fuel Pump Replacement
Aug 7, 2012
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?

when I turn key I should hear fuel pump, I don't. I can jump pump & it will run but it still won't start. I reset inertia switch, switched pumps (new one) still won't start. What next????

I've got a 2000 ranger w 158k miles, been having issues with a misfire over 65mph, and it's been throwing a check engine O2 sensor code. One of the probable reasons for the O2 code read low fuel pressure... so my husband got the bright idea of replacing the fuel pump.
That turned out to be a big story in and of itself. BUT we got it replaced with one that works, however.... now it won't start!!! You have to pump the gas and like crazy and hope that it'll start, it will eventually... but not without a bunch of coaching.
Once it's running, it's running ok. The first day after replacing the pump it was AWESOME, ran like it used to years ago, no misfire, smooth as could be, no rattle, no check engine light. But it all came back it's misfiring again, rattling when you accelerate, and the check engine is back on. I haven't had a chance to go run and get the codes ran again, maybe tomorrow I'll be able to do that in between errands. Oh, and we are gonna replace the fuel filter at some point in this week...

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?

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.

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.

Any way to tell if the ECU is faulty? I hooked my analyzer up to my friends 1988 Ford ranger 2.3L and it wouldn't even detect that the ignition switch was on. He was driving it the other day and is shut off on him while he was making a turn and it wouldn't start back up. We have rebuilt the distributor by replacing the pick-up, rotor button and cap, and we had the ignition module tested and found it was good. We have also replaced the coil. When the ignition is turned to the on position, the fuel pump comes on and never cycles off.

I have tried about everything i know about cars on this truck!! It ran great when I got it until a head gasket got blown so I tore into it and replaced them both torqued heads to specs. Made sure valves wasn't to tight. Distributor is in correct spot timing is correct had ignition module tested good!!! Coil tested good replaced both fuel pumps and put new tank and sending unit in the truck b/c it needed it new fuel filter replaced return line firing order is correct 1 4 2 5 3 6 it is getting fire it will crank and crank sometimes act like it is going to start then not also I can get it to run for about 3 sec on 3 or 2 cylinders it seems to have plenty of compression as well!! only thing really I can think of that could be wrong is computer? Also one last detail tried pull starting it as well still wouldn't go.... V6 2.9L...

My 1988 XLT 4x4 2.9L truck can't make up it's mind. Oil light comes on when ever it wants. I replaced it with a new one to make sure it wasn't bad. My lifters start clanking then they'll stop making noise when ever . Oil light goes out.Runs great. I let it Idle and once warm oil light pops on again. Rev it up light goes out then comes back on at higher rpm. Let Idle lifters clank again...and so on. seems erratic. Weak oil pump???? slop plugging pick up screen??? I'm running 20w50 oil is has 188,000. It ran today for 1/2 hour no oil light no noise then Here we go again..clanking valves ,oil light on...

The fuse and relay have been tested. There actually is 5 volts at the fuel pump. The truck was running OK when the clutch went out. It wouldn't start after the clutch was replaced. The inertia switch is OK. I don't know where to look now....

Anyway just got a new fuel pump put in my 99 3.0 Ranger and now after it's warmed up from a few miles it starts to choke and almost die. No CEL comes on and I just put new Motorcraft plugs in and still the same thing. I read something about maybe cleaning EGR.?

1987, 2.9 ... I got all my wiring repaired and replaced both the intank pump and the high pressure pump, for a few days it would fire right up as soon as you hit the key but it had a miss (the pumps shut off after a second or two with the key on "RUN"). I tore the throttle body off and cleaned all the carbon out of it, when I put the throttle body back on I noticed that the engine to body ground was loose so I ran a new piece of 4ga from the intake manifold bolt to one of the master cylinder bolts.
After I did this I went to start the truck and no go, the fuel pump turns on with the key but then it wont shut back off until you turn the key off. if you try and start the truck it will crank but wont fire, after about a half hour of cycling the key and cranking it will start to put a little bit then a few tries later it will start but sounds rough when it first fires. I thought it may be a stuck injector so I ran some cleaner through the Schrader valve on the rail. Still have nothing, both pumps do run but still don't shut off after a few seconds like they should and now it wont even try to start.

My '94 4.0L XLT has hesitated to start a couple times lately. Then, after sitting for a week while we were on vacation, the truck would not start at all today.

I read about the fuel pump relay, so since I am not made of money, I decided to change that first ($16 vs. $100). After installing the new relay, the truck started! I put the old relay in the box and tossed it into the glove box.
After lunch, and some thought, i decided I wanted to put the old relay back in and see what happened. Guess what! It started with the old relay as well! I also noticed that the humming/buzzing sound the fuel pump makes when the switch is turned on was different with the new relay vs the old one. I put the new relay back in, but now I am unsure where my real problem lies. Intermittent relay, or fuel pump on its way out??

I can't get power to the fuel pump on my 91 ranger 3.0 5 speed. I just bought the truck and replaced all the relays checked all the fuses under the dash and under the hood. If I jump the relay it comes on and wont go off.

I know where the filter is, i know how to bleed off the pressure. Im wondering if those clips are easy to slide off to remove the filter from the lines?

I have inherited a 1992 Ford Ranger 4.0 with an unusual problem. When the temp drops outside the truck will not crank. The relay is coming on for a sec or 2 to bring the system up to pressure but the pump never turns on. This happens every time the outside temp drops below 60. I can wait until later in the day or until a warm day, hit the key and drive it till it runs out of gas. A week later (and another cold front) and it is sitting dead in the front yard. I have traced the grounds, checked the power thru the relay (and replaced the relay too), but it still does this. What I want to know is am I the only one to ever run into this and if not then what is causing it. Pump shows no sings of trouble on a 70 degree day, even runs the proper pressure and volumes. I am stumped at this point and I am ready to try replacing the pump (though the one in it looks brand new). comments?

My 1996 Ford Ranger's Fuel Pump- Fuse keeps on blowing... (Fuel pump is new)... We need to find where the short is coming from!

I'm working on a truck for a friend's mother and all of the tests that I've done point to the fuel pump. However, to make sure the pump is getting voltage past the large connector block under the cab, I would like to do a pin-out test before I pull the tank (or the bed). The pump will not run/prime in KOEO test, the relay is good, as are all of the fuses and the inertia switch.
Looking for a wiring diagram handy for this purpose? I've look all over this forum and searched quite extensively and I haven't found one for this year. Since it isn't my truck, I don't feel like purchasing a manual. I'm working on a 2003 3.0 2WD Auto.
If a wiring diagram isn't available, what colors are the wires going to the fuel pump? That way I can at least test the ground and the positive.

Just replaced fuel pump and now it turns over but won't crank. I have checked the fuel rail. Pressure is fine. Checked coil pack I'm getting spark. Still won't crank. Checked inertia switch it wasn't tripped. What next? 2003 Ranger edge...

I've been driving 93 ranger 3.0 4wd since last fall. first week I went to start and fuel pump relay had blown. I put a new one in and been driving since fine, till today. Now when I try to start, if it starts it will run fine all day as long as you don't turn it off. If you turn it off and restart half the times it will pop relay again. My fuel gauge has been stuck on full since I bought it also. I'm wondering if maybe pump has got had to start and drawing too much current...
