Your welcome.

Check vacuum, check the MAP, check and make sure the distributor isnt twisting around or loose. You can pull the wire off the injectors and make sure the contact isnt garbled up either.

i already had checked all that, i just got done removing TBI
unit and totally disassembling it and while i was at it i did the raised regulator platform mod to it and all back together and reinstalled and the damn thing still goes and no restart, but once it does start it runs perfect til you shut it off and try to restart and get no fuel spray at all.
