Passat (B5) :: Marker Light Comes On When Fuel Pump Is Running
Apr 11, 2013
More electrical gremlins. The car is a 2000 1.8t, it has had some running issues since I got it a few weeks ago. I replaced the ECM (had water damage), fuel pump relay and battery and it was running fine all week, my wife went to start it after work and it died when she took the e-brake off. I went to her work to get her and noticed the rear marker light was on when the car was running. Got the car home and now it wont run for more than about a minute and the light comes in when the fuel pump is running, turn the key but don't start the car and the pump and light come on for a second and go out. Start the car and the light stays in until the car dies.
Is there anywhere in the system these two circuits are connected? Do they share a load relay anywhere?

I just bought another 1991 Ford. This one is a 1/2 ton XLT Lariet with the 302 and for the first time I own a short bed. I also have a 1991 F-250 XLT with a 460 and a 8' bed.
Here is the problem, ( I think) it will not run or at least not for long. The fuel pump, which I am guessing is in the rear tank will not stop running. On the F-250 the pump stops running after a few seconds after I turn on the key.
Where should I start to find out my problem with the fuel system?

I have an 87 F150 4x4 4.9L EFI with a single tank. Fuel pumps keep running even when the key is off. I tried swapping relays but the problem still exists. The engine will start and run OK for about 15 secs. then die. I installed a new low pressure pump, high pressure pump seems to be OK. I also installed new fuel filters. I dont want to just throw parts at this truck, where do I go from here?

5.4 L, Engine runs if primed at the intake. Fuel pump can be heard running but no fuel gets to the engine. Truck is mint and being sold real cheap due to this issue.
Fuel Pump? Filter? Both? I haven't seen the truck, a friend is considering buying it and rolling the dice it is a quick fix. Fuel is in the tank .....

Just did a complete engine rebuild on 2003 Explorer. All back together....have new battery, starter working, spark at plugs lol crank but no start. Next check is fuel. Fuel pump WAS working fine when timing chain guides went about a year ago...(had to rehab 2 parents and finish bath remodel before pulling engine) So... 1 year later I can't seem to get the fuel pump to work. I checked all fuses and relay. The fuel gauge is working - full tank.

I worked with my buddy troubleshoot and remove a faulty fuel pump. He received it a week or so later and did the install himself. After this, he states that while pumping gas at the gas station the nozzle no longer cuts off automatically when full causing overflow. He says this has happened at different stations and different pumps. I told him to go double check connections and that everything was sealed. I am wondering what could be causing it..

I been working on this car for several weeks now. I have change,
1. The starter.
2. New Battery, New Plugs, New Crankshaft sensor.
I even change the belt tensioner because is was going bad (Broken). In fact I can hear the full pump running. After doing all this the car still not turn on. there is full in the full injector.

I have a '95 Chevy Caprice Classic 4.3L Sedan, and it cranks but does not start.This started happening after about a year of the car just sitting in the driveway. Before she sat for that year, she ran just fine.
I am under the impression that the problem is the fuel pump, it is NOT running when the ignition key is turned to the "on" position,this is very confusing because a volt meter placed on the connectors going directly into the pump motor shows 12+ Volts when the key is turned, for about 2 seconds, as it should, however the pump motor does not run. Also, I have already replaced the pump relay AND the entire pump assembly (though the pump I used as a replacement was also pulled from a junkyard vehicle).
The MOST confusing part is, when either of the fuel pump motors that I have are plugged directly into the car battery, they run just fine.

I have been chasing down what was a perceived vacuum leak...
My Ex (V10, 4x4, 217K miles) started to have an intermittent rough running/no power situation very randomly. No codes on the scanner, and no real apparent cause or condition to pin it down. I noticed what sounded like a like throttle ping...figured it was a vacuum leak someplace in the spaghetti under the hood.
I began to run down the possibilities. I have recently had the entire suspension replaced and upgraded all 4 corners to Power Stop brakes. Figured it might be something related like the classic lines to the hubs.
Replaced the vacuum lines to the hubs - ran OK for a bit, then rough start/idle/no power.
Replaced the vacuum switch for the hubs - ran OK for a bit, then rough start/idle/no power.
Replaced fuel filter - ran OK for a bit, then rough start/idle/no power.
Ordered a new vacuum reservoir...
While waiting on that, changed all 10 plugs and coils. Not. Cheap. Ran OK for a bit, then rough start/idle/no power.
Replaced IAC - ran OK for a bit, then rough start/idle/no power.
As I was getting ready to install the vacuum res, it just croaked. it would turned over like it wanted to start, but wouldn't catch.
Of course.... So, now it had to be towed and yes, the fuel pump puked and that was that. I've never had one do anything but just quit suddenly before, so lesson learned. Evidently these pump can act up for a bit before they die.

The running lights and marker light on my trailer no longer work when I connect to my 2008, F150 4x2 Supercab, XLT, 4.6 V8 Auto with Tow package. Brake and turn signal work fine. The running lights, all the lights work on the trailer work when I connect to my Chevy so I know the problem is in the F150.
I have confirmed the ground to the 7 pin and 4 flat connector is good so I am thinking it must be a fuse or relay. Which specific fuse or relay should I check or replace?

First it was the whole spark plug debacle. Now it's the "fuel pump module". Story starts a several months back. On a moist day I was headed out and the truck ran very rough, "clunky", like it wasn't getting gas. After 15 miles and a stop truck ran fine. Didn't think much of it and truck ran fine for month or so. I was then away for a couple days and came home to find my truck wouldn't run (started briefly then died). Local mechanic thought it might be a fuel pump issue but then got truck running thinking it might have been a delayed inertia switch in front panel (I had hit a deer a week or 2 prior). Again, not thinking much of it continued to drive truck with no issues for awhile. Then one rainy morning on my way to work the truck was running very rough and "clunky" again. It died several times and finally for good.
After getting it towed to the mechanics, he figured the fuel pump was finally shot. The end to my long story is it was the fuel pump module (luckily a lot cheaper fix than the fuel pump) - half of the housing was gone (corroded away) adn moisture was shorting the pump electronics. Why, if this module is half encased in plastic do the engineers feel the need to encase the other half in metal (appeared to be cast aluminum)??!!????!! Of course it makes sense to have an electrical unit that is mounted underneath the truck where it can collect all the moisture, snow, salt from the road encased in a corrodable metal housing. No no, don't put it all in plastic, just half of the unit. MAKES PERFECT SENSE!! I thought to be and engineer took some sort of brains and common sense. Must be not at Ford. I can't be the only one with this issue and wondering WHY!!! - it must be widespread??

Our 2012 camry se had a problem with the fuel pump running when the engine was off. Several hours after we came home I went into the garage for something and heard a humming noise. First thought was a distant neighbor using a leaf blower, then realized it was coming from the rear of car. definitely coming from gas tank area. Turned key on, then off and noise was gone.

Truck quit running yesterday suddenly and unexpectedly. It sputtered briefly and the motor total quit running. I pulled over and tried to start and it briefly fired but then totally quit. Got towed home. And now testing to see what all to repair..Thinking fuel.
I don't get any codes from the tester with KOEO..just the good to go etc..no codes or the good to go 111..etc. Guess this problem can't be identified without motor running.
My wiring diagram doesn't give me all for my Calif car..I don't see where the relay is but my fuses are all good, and I'm getting voltage when I crank the motor at that inside firewall switch on both its wires(incoming/outgoing)..forget what its called..Inertia Switch?..that will shut off fuel pump during accident or impact etc. And I've read that this switch is upstream of the relay(if I read that post correctly) so guessing it's the pump itself that is bad.
Does that sound right? Should I go ahead and pull the fuel tank etc and replace the pump? Or is there more testing I should do? When I turn the ignition key on..the pump makes zero sound. That's not the way it normally operates. Usually with the key on the fuel pump comes on momentarily and I can hear it. Forget how to drain the fuel tank etc..I don't see a drain plug? I did it once many years ago..but forget how?

I have a 2001 f350 v10 that has been giving me fits. has 88000 miles. cranks and starts when cold or fuel pressure is below 40 psi. SES light will flash when it stalls and fuel pressure goes from 30 while running to 40 and the fuel pump runs continuously when this happens and truck will not start. replaced crank sensor and fuel pump was changed about two months ago. if I relieve fuel pressure it will start and run for short time then stall and fuel pump stays on. all fuses are good. I am at a loss.

I installed an aluminum flatbed on m 2004 F250 5.4 and when I was wiring the lights, I accidentally shorted the marker/running lights to ground. The fuse is not blown (17), the dash lights come on. I have checked for power to the other lamps and there is nothing. I am looking for any information that would lead where to look for the cause.
