Sorry about the length in advance
I just bought my car recently with most of the stuff already done by the previous owner (upgraded turbo, IC, injectors, chip, 340 walbro, and other bolt ons). It has been running great until a few nights ago. I went out to take it for a spin and noticed that the fuel pump wasn't humming with the key in the 'on' position. The car turned over fine but would not fire, so I pushed on the shrader valve on the fuel rail and didn't even get a drop of fuel.. I was about to pull the line off before the fuel filter to see if there was any pressure at that point in the system, but decided to crank it once more before making a huge mess on my garage floor. Sure enough, I hear the pump run and the car starts right up. I let it run a minute and shut it off for the night.
Tonight I get in and hear the pump cut on momentarily with the ignition key in the 'on' position, but stops just before I try and start the car. Yea, the motor fired right up, but promptly died bc of no fuel.
The pump doesn't sound like it is dying, it just cuts on and off so abruptly I'm convinced a bad connection is the problem. What I don't know is how to go about tracking it down.. can someone tell me the basic wiring layout of the fuel pump (is it wired directly into the fuse box, etc)? Also, the guy installed a Volt Booster for the pump.. I know it's a controversial product, but he was convinced it's necessary for large pumps. Does this change anything about how the pump is wired, or possibly my problem? FWIW, I pressed the little test button on the volt booster and the light came on, so I assume it's getting juice and passing it through to the pump.
Again, sorry for the rambling, just trying to not leave out any details.
Thanks alot
