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?

Customer: replied 1 year ago.
NO,ALMOST RUNS N STARTS LIKE IT IS TOO FAR ADVANCED,BUT THERE IS NO TIMING ADJMT
Expert:  Ron replied 1 year ago.

Your correct, timing is controlled by the computer and is not adjustable, So you saying it cranks hard?

Customer: replied 1 year ago.
Expert:  Ron replied 1 year ago.

With the amount of miles you have on the engine I wonder if the timing chain has jumped.

Customer: replied 1 year ago.
Wouldn't it run badly most of the time ifit did
Expert:  Ron replied 1 year ago.

Is the computer system setting any fault codes?

Customer: replied 1 year ago.
Not that i can tell
Expert:  Ron replied 1 year ago.

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.
