need help

Rate this Entry
i picked up a 95 c1500 vortec 305 (5.0L) for 900 bucks. it came with a extra P/S door and extra complete front clip. power plant to the wheels is super clean no leaks what so ever.

when i got it it had a new fuel filter, new throttle position sensor, and an alarm with no remotes. with the alarm removed it hardly starts. when it does, it stays on momentarily but then shuts off. it turns off even quicker if throttle is opened even alittle. i hooked up to obd II and the only code that came up was MAF.
MAF is now replaced. nothings changed.

what has been done;

fuel pump works
fuel pressure is at about 62 psi when cranked and maintained at about 55psi
when i turn it off pressure is maintained at about 12psi for over 15 minutes
spider injectors flushed and all spray in order
ngk platinum plugs

im sure theres more that i cant remember at the moment


PLEASE HELP BEFORE I DRIVE IT OFF A CLIFF or should i say PUSH IT OFF

    I would check the electrical. May jot be grounded somewhere. And just to let you know 96 was the first year they started with the vortec.
