I had several fault codes, egr, ecm 6 pin. Crankcase position sensor(replaced). Doesn't always do it, just if you have a important appointment. Embarassing at the gas station. Replaced coils, starter, fuel pump and filter.

Neixt time it refuses to starts do below immediately don't wait for nothing to catch it -if its a fuel or spark problem do below

Lets do below for a start to determine if its fuel or spark related issue and get back with some results

Get a helper disconnect a sparkplug wire or 2 and ground it to the engine atleast 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
