Ok guys, I need to know if I may have burned out my fuel pump. Here is the story. So I need to put in a new intercooler, get that done, and I forget to plug in my MAT sensor. I drive it all day (running pig rich) and do a auto x -8 heats-(mind you I'm running dsm 450s and 15 psi). I get home and start to look for why it is running so rich and find the sensor. OK now plug in the sensor and start it up. Life is good. I fool around the house and go to leave and now the car won't start. So I start to look around and I notice my fuel pressure is at 0. Hmm not good. Ok so I start to check the relay/pump all else. I find the pump is not priming (I can usually hear it whine to prime when the key is turned on but it is not doing it now). I can unhook my fuel line and only a trickle of fuel comes out. I check for power at the pump and there is 12.xx + volts at the pump and like .35 volts on one of the wires *shrug*, no idea if that is right, but there is some power to it. Anyway my current pump is a walbro 255 lph HP. I need to know if there is some way for me to check the pump to see if it has really gone bad, or mabey I am not testing this correctly.

Sounds like just bad concindence and you pump just went POOP. to confirm this and make sure before you buy another take a 12v source liek a drill battery or another car battery. run the power and ground to the pump and see if it powers up. if it doesnt them the pump is bad. you pretty much have a good handle on it, no hidden tricks with this one.

thanks terry, it was the relay, so i just did the fuel pump rewire mod. Seems to work fine now. I swear something breaks on my car daily .
