1994 Buick Regal Gran Sport

Yes this is a GM but was gave to me it was my Grandmother's car so much for a free car.I have had the heads reworked and surfaced it had a warp head.It started fine put about 30 miles on it shut it off and now it only starts up for a few sec.then shuts off.I have changed the ecm,ing. swicth,crank position sensor,fuel pump and relay checked all grounds and oil pressure swicth.This thing is about run me crazy I have over a $1000 does anybody know what makes the injectors fire on a 3800 tuned port I am about ready to take my losses and sale it for scrap.

get a fuel pressure gage on it . . still can be the oil pressure wireing . . cranking and key first on bypasses the o/p unit

Jim run a wire all the way back to the fuel pump and see if that fixes it, I take it jumping the pins on the O/P switch did not change anything? There may be a bad ground or corroded plug in the wiring going back to the fuel pump. I have even had bad new fuel pumps before, Autozone, Advance... all sell the same shitty pump.

Talk about being pissed off I layed on the ground in February during a freezing rainstorm -30 temps -50 windchill installing a fuel pump in the parking lot of my ex-wife's college only to get it completely done and the pump be bad and have to do it all over again 20 minutes later.

Could be a problem with the security system. My buddy's car did the same thing and it was the body computer, apparently it's a pretty common problem.
