clueless in Miami

[dec010974]

As the title says, I'm totally clueless. a buddy of mine has a swapped
5.3/700r4 into his 1994 chevy 1500. the swap was completed a while back. he ran into a stalling problem. he says, when the vehicle is cold, its hard to crank/run. he starts by vehicle, crank/run, by activating the fuel pump for a few seconds (5-10 seconds) turns the ignition, the pcm/fuel pump, primes the fuel rail/system, he turns the key, and starts the vehicle. I know this sounds crazy, but it is. I am like, WTF. he says he has problems starting the vehicle if he doesn't add the extra fuel. I told him that GM's design, of the fuel system, is almost flawless. why would you wire your vehicle like this? he says it works. I think he is asking for trouble. I told him, THE PCM IS smarter THAN he is and doesn't need assistance from you. I think its something in the tune, bad gas, dirty injector, or something else. need advice. I checked all the ignition sources. all sources have power such as maf, injectors, coils, O2 sensors, etc. I check all the connectors, grounds, cam sensors crank sensors, etc. give me some ideas. thanks in advance. clark. BTW,when I was there to check vehicle over, help him with his PROBLEM, it didn't START with his TRIED and true method either.
