Ford Repair Questions? Ask a Mechanic for Answers ASAP
Hello and thank you for your question,Can you connect a fuel pressure gauge to the fuel rail service port and check the fuel pressure?
Your correct, timing is controlled by the computer and is not adjustable, So you saying it cranks hard?
With the amount of miles you have on the engine I wonder if the timing chain has jumped.
Is the computer system setting any fault codes?
I think I would start with the basics, remove the spark plugs and run a compression test, install a fuel pressure gauge and monitor the fuel pressure while the problem is occurring, normal fuel pressure should be right at 32 to 45 PSI. I would also scan the computer system to see if there are any stored fault codes.
