Have Ford Questions? Ask a Mechanic for Answers ASAP
Hello and thank you for your question,If you are sure you have good fuel pressure , can you check and see if you have injector pulse. You can do this with a standard 12 volt test light by placing the test end on the red power wire at any one of the injector connectors and then place the ground end of the test light on the other wire with a paper clip in the connector and crank the engine over. If you have pulse the light should flash. If you do not then the light will glow steady. Let me know and we can work from there.
Okay let me know and we can work from there.
All you need to do is book mark this page. Im here for a while yet today and all day tomorrow.
In order for the engine to start and run you need proper fuel pressure, 32 to 45 PSI, good spark to the spark plugs and injector pulse. If you are sure you have all three then the engine should start. Are you sure you have injector pulse?
Well if the injectors are actually pulsing and you have proper fuel pressure it should stay running. If you pull up the injector rail up and crank the engine over do you see fuel spraying out of the injectors? If you check this be careful to stay away from an ignition source.
In order to see if there spraying you are going to need to remove the 2 mounting bolts and raise the rail.
Okay , just be care to not get close to an ignition source if. Unplug the coil to avoid a fire if they are spraying as the should be.
