Just two days ago, my truck had done something rather strange. After about a 10 mile drive, I pulled into the driveway, parked and shut her off. About 30 minutes later, I went out to go start her, nothing but cranking. I thought about blaming the recently installed month old fuel pump but I can hear the usual soft hum when the key is turned for about 1-2 seconds. I can hear this hum again when the key is turned off. Although I haven't checked the fuel pressure yet, I do believe the pump is fine. It sounds just like it did when first installed. The truck ran like a champ during the whole 10 mile trip and while idling in the driveway.

The truck did start with starting fluid but as soon as the fluid was burnt, nothing. There's clearly no fuel getting to the engine. I'm not sure where to start.

 

Post up those fuel pressure test results.

 

I haven't yet done one. I'll get it tomorrow.

 

I haven't been able to build up more then 47-49 PSI. From what I read, I need at least 50 PSI to open up the poppet style fuel injectors to start her up. Figuring how new the pump is and have ancient the filter looks, I'm thinking of replacing the fuel filter. I just can't find any guides or anything on how to do so.

 

To whom this post might benefit, the problem ended up being a faulty fuel pump. Got the truck running after priming the pump using a jumper wire to jump the fuel pump relay (pins 30 to 87). I then put the relay back in and the truck started and ran. I was able to back it up about 20 feet and idle for about 10 more seconds before it stalled. I was able to get it started several times using this method and even revved it up to 3000 revs. It would then just stall for no reason. The fuel pump had a warranty so I had another shipped out. I replaced the fuel pump and the truck has been running great ever since.

 

Thanks for the update, what brand pump is it?

 

It is Parts Galaxy. It was some cheap generic aftermarket brand. It was all I could afford at the time.
