Replaced cam and crank sensors, fuel pressuer regulator, fuel filter, and we've checked the pressure on the fue pump, all fuel lines but still the engine will rotate but not start. Help need more idiea of why the car won't start? It use to run perfect.

Cranks and w/n start

Get a helper disconnect a sparkplug wire or 2 and ground it to the engine at least 3/16 away from ground -have helper crank engine over-do you have a snapping blue spark? If so-you have a fuel related problem, check the fuel pressure to rule out the fuel filter/fuel pump/pressure regulator and listen to the injector/s are they pulsing or hook up a noid light. No snapping blue spark continue to troubleshoot the ignition system-power input to the coil/coil packs, coil's resistances, distributor pick-up coil, ignition control module, cam and crank sensors and computer Note: If it doesn't apply disregard it
