i meant to say that it sounds like it is turning on
Ford Mechanic: AMEDEE, FORD TECHNICIAN replied 8 months ago

Got it! Thank you for that information.

Does the engine run on starting fluid?

Ask Your Own Ford Question
Customer reply replied 8 months ago
have not tried to use starting fluid
Ford Mechanic: AMEDEE, FORD TECHNICIAN replied 8 months ago

Got it!

If the engine is cranking over but not starting, you need to see what it is missing. Spark, fuel and or compression.

Chances are it is a fuel or spark issue preventing it from starting but you will need to check and confirm this.

If the engine runs on starting fluid, then we need to check the fuel pump operation and installation. Maybe we have the wrong pump or maybe the fuel pump was installed incorrectly.

Maybe the fuel pump circuit has an issue or maybe it is not even related to the fuel system at all. It could be a no spark condition caused by a faulty crank sensor or computer issue. Just be sure to check all fuses as well.

Keep in mind this is a "starting point". My goal is to give you the best experience possible! I hope I have earned a 5-star rating!

Because of your expertise, you armed me with enough ammunition to win the battle with the dealer. They are installing a fuel filter and fuel pump at no charge to me.
