New engine 383 Tpi for swap meet after market harness.Put a Painless vats bypass and still no injector fire.Fuel and spark but no fire to injectors while cranking.Will the knock sensor cause this also or a bad bypass module,Called Painless yesterday they say it still could be their module.Have oil pressure with the 3 prong switch.The computer runs my other tpi equipped car.So I'm stumped Please any help don't like spinning over new motor that long.Thank flatmotor40
