Re: help 5.7 tpi wont start
you can check for power at the injectors with the koeo and will have 12v if you don't check inj 1 and 2 fuses. If you have a analog vom you may see the pulse when the engine is cranked. The ecm grounds the injectors to fire them. so you have one of four issues wrong, you verified correct fuel pressure so it would be a vats issue or a bad ecm or ecm ground behind the passenger cylinder head or no continuity back to the ecm from the distributor through the dist to d8 or d9 at the ecm.
