Looks like I mat have spoke to soon about my truck running fine with the new Fass fuel pump. I have had it in for about 3 weeks now and I am now having trouble getting the engine to start. The truck seems to start up fine on the first try then right after it starts it lobes a couple of times then shuts off. After that I just hit the starter for a while then stop hit the starter for a while the stop and so on until it starts, 3 time now this has worked. I just tried taking the inline fuse out of the fuel pump thinking this would relieve the high pressure at start-up and the truck would fire right up. But that was not the case so I put the fuse back in and just kept trying the starter til it finally starts. Once it starts the truck runs fine.Is this a for sure sign that my injection pump is bad? Also is there any reparing the pump or is my only option a new one.
