Hi Tom. Have you double checked the firing order?

Do you have a timing light so we can see if timing is correct?

Customer: replied 2 years ago.
have check everything timing is good make no sense to me. Is there a chance that module or pick and or coil is going bad or is bad
Expert:  Jason replied 2 years ago.

That is why i want to check timing. Do you have a timing light that you can hook up to the #1 plug wire and read the timing while a helper cranks the engine over?

Customer: replied 2 years ago.
Give that a shot one more time
Expert:  Jason replied 2 years ago.

Even with the engine cranking over, as long as you have a good strong battery the timing will read correctly. And it should read roughly 6 to 8 degrees BTDC at cranking speeds. Let me know what happens.

Just checking it, any progress on the timing check?
