1998 K3500 5.7 gasoline truck cranks, but will not start. Found low fuel pressure @ about 35 PSI. Replaced fuel pump assembly in the gasoline tank, started truck drove it home, but next day it wouldn't start, I measured fuel pressure, and now have 60 PSI fuel pressure, but engine will start, only if I pour in a little gasoline. This must be an electrical perhaps missing an input signal to the computer, since some common signal enables the fuel injectors to fire. My assumption is the fuel injecto

Where exactly is the fuel pump relay and fuse? I have no fuel pressure at all, i don't really feel like its my fuel pump, (hoping not anyway, don't want to have to pull the tank). Im thinking its the crank shaft sensor (which i have, just haven't put it in yet). but would like to check the relay and the fuse. Anything else it could be besides the crankshaft sensor? The way it all happened is about 4 months ago, my wife called me, the car wouldn't start. So i met her and just reached across from

1996 Toyota T-100 starting problem--- when I first turn the key, I hear nothing. After engine cranks over once or twice, I hear a clicking noise around the passenger engine compartment. I'm assuming that it's either the fuel pressurizing or the fuel pump relay. I read online that both the fuel pump relay and the oil pressure switch enable the fuel pump to turn on. What I understood is that if the fuel pump relay goes out, oil pressure switch turn the pump on. This explaining why it has to c

Ford ranger 2002 the fuel pump will not pump in cold weather, when it is colder than @34 F. In warm weather when I turn the ignition key I can hear the fuel pump pressurize and the truck will start. In cold weather the the starter crank the engine, but fuel pump will not pressurize or pump. In cold weather if I use a heater to warm up the engine compartment, then you can hear the fuel pump pressurize and the engine will start. Hope you can help, thanks.

Here's one for the books. 2000 Jaguar S Type 4.0 Sport - no fuel pressure past fuel pump. Checked inertia switch, fuel pump fuses and relay - all good. Installed new fuel filter, fuel pump was shot - replaced fuel pump and I can hear the pump prime when turning the ignition switch on, but NO fuel pressure at fuel filter and fuel rail. Engine started with starter fluid, any help would be appreciated.

I have a 98 Buick Century thats starting to get up there in the mileage. (165k miles). Recently, I changed jobs and had to run the fuel tank under 1/4 full for quite a while, which I know isn't good for the pump. Anyway, the car stalled before i thought i should be out of gas, so I pushed it to the station and threw in enough for a half tank. Tried to crank it, and now it just turns over without starting.

I have a 2004 BA Falcon XT which has a problem starting when warm. When hot or cold it is OK but if left for half an hour or more it takes a while to start or I have to put my foot flat to the floor. The mechanics have been trying to trace it and so far have had the injectors cleaned, throttle body cleaned and fuel pump replaced (it was pumping at half pressure anyway). They have had it on the scope and it all seems to be firing and squirting at the right times. They said they have a couple more

I have a 1988 camper it's on a Ford F350 chasse with a 460 ci. engine. Has one gas tank with a low pressure pump in it and a high pressure pump on the frame rail. The truck runs for an hour and dies. at that point there is no fuel pressure or spark and the high pressure pump is hot. I replaced the high pressure pump and the fuel pump relay but it didn't help. Can anyone tell me why the high pressure pump could be getting hot and would it cause it to not have spark ?

1985 Firebird 2.8 ltr, automatic, FI. I replaced the fuel pump approximately 5 years ago. Car was operating fine and suddenly lost fuel pressure, when I checked the pressure I only had a few pounds of pressure and that was all. Could it possibly the fuel pump relay or maybe a wiring harness issue or would I possibly have to replace the fuel pump again? When the pump was originally replaced, the relay nor the harness were replaced. Please help.
Sounds like a bad fuel pump. The relay would only turn it on or off. If it's off you'd have no fuel pressure. Make sure you replace the fuel filter and the filter 'sock' on the pump as well when you change it. ... 1985 Pontiac Firebird

If the fuel pump in an Holden Barina 1998 model is gone , not working , what is the main part of the fuel pump is important to change rather than to change everything meaning the top cover , the middle main fuel pump that fits into the fuel kit that has the measuring section . What I am trying to ask is that if I am having with the fuel pump failing to start can I just change just the Main fuel pump that sits into the base plastic frame with the measuring unit.
Yes you can just change the fuel pump, there are genuine and aftermarket options available, You need to remove the original pump from the cradle and this will allow you to confirm the size of the replacement pump. ... 1992 Holden Barina

1989 Mercury Grand Marquis I have installed the following: new fuel pump relay, fuel pump & filter, new distributor, coil, ignition switch, replaced two damaged lifters and lifter retainer and fuel pressure valve (located on the fuel rail). This is what is occurring. The engine tries to start, but does not. The fuel pump does not turn off once pressure is reached, continues to run. If the car starts, the fuel pump continues to run. The engine, when it runs, does so badly. Fairly recent plugs
