Question about 1992 GMC Sierra K1500

1 Answer

Can a fuel pump work intermittently or do they just die

Truck just died...had to leave over night then went back to it and just for kicks tried to start it...fired right up as normal. Does this seem more like a relay issue?

It could be the pump, but most times its the relay. Easy enough to check the relay by swapping it with another or a new one.

Testimonial: "Thank you Stephen, fingers crossed its the relay...would probably be an all weekend project to change the pump.."

2001 explorer sport , fuel pump? vacuum leak? 619 scan tool data provided, any suggestions/solutions


The fuel pump is suspect but I believe there's also a fuel filter inline on the underside of the drivers side chassis. Fuel works off pressure so if the filter is clogged, the pressure remains between the fuel tank and the filter. Once the fuel has siphoned off between the filter and injectors, it dies but because there's positive pressure at the fuel pump, it won't come on until the pressure slowly seeps past the clog after hours. It's worth a look!

This could be a fuel pump problem try starting fluid if starts and dies then have a fuel pressure test done to confirm pump failure.

1988 ford ranger ( 4 cyl ) Fuel pump kicks on, motor starts and runs approx. 5 to10 min. and dies. Turn key back on and can't here fuel pump.


It sounds like your fuel pump is overheating. Once it gets too hot the bearings swell and the pump locks up. When it cools, they contract and the pump works again. It is also possible the fuel pump relay is having a thermal failure. You can determine this by hooking a voltmeter into the fuel pump supply wire and keep it where you can see it while it is running. If the voltage goes down and then the truck stalls, it would be the relay, if the voltage goes down after the truck stalls, it would be the fuel pump. Since the pump is only running when the engine is running, once the engine dies it'll turn off the fuel pump so it is important to pay attention to what happens first.

Intermittent no start, very strange, very confusing


Sounds like fuel pump going out. I was told by a friend that the pump can get stuck and that by knocking on the fuel tank or by attempting to start that it can kick the pump out of the bad spot and it will start. But it is a sign that it needs to be replaced.
