Re: Help Me! 1999 Ford Escort LX problems
If there's a main relay problem your car shouldn't even crank. The fuel inertia switch should be down when it's not triggered, so what you're seen is normal. A fuel inertia switch that has been triggered only disables fuel pump, NOT injector pulse or spark, that's why I mentioned hooking up a Noid Light.
If the Crank Position sensor is faulty there will be no injector pulse AND no spark because the PCM doesn't know where cylinder 1 Top Dead Centre is. You will however hear the fuel pump run when turning the ignition on but it will be disabled during cranking. Hope this makes it a bit easier. cheers
