We always tackled no-start issues with this formula./
FIVEM! F=fuel & on that car you need 100psi of fuel pressure I= ignition & you should have enough spark to jump a spark plug with a gap of 0.1" V=vacuum & you should have 150lbs of compression E=electrical & you want to make sure that the OVPR is powering up the computer M= mechanical & of course make sure that the timing chain is intact & cams are in time OVPR= over voltage protection relay
