I do have 12 volts at the coil terminals and at the injector terminals. I checked the grounds at the pcm also. Jim

its odd it doesn't bust off for a second then die. Make sure the wires going to the cam and crank sensors didnt get pinched between or cut by something. Do you have fuel pressure at the rails?

56psi at the rails.The guy that did my wiring and flashed my pcm said the all work done flashing is with all connectors in placeand tested that way. Is that common? how much do most charge for flashig a pcm
thats bullcrap IMO. You can't test a PCM without putting it on an engine and seeing if it runs or not. Bad burns happen all the time. Who is your tuner?
