I thought of that as well. I started in the troubleshooting section of the FSM, and the first few were the obvious things i already have in place as far as the 3 elements required for an engine to run. i started with the coils and checked all the values and they are in spec. bought new plugs, they seems to spark better, but havent installed them yet to try and see. checked the coil wiring and confirmed voltage, grounds and continuity.
I replaced the fuel pump first, and noticed that the check valve washer and rubber flap under the fuelpump filter were not in the module. im sure that will probaby cause a performance issue but, that will come later. checked the fuel pump pressure inline per the manual and
spec is 40-45psi and im around 50psi, although pressure drops quickly, and im thinking because of the check valve.
i was starting on the injector side of testing. i cleaned the injectors (bench style with spray cleaner, and a switch to activate the solenoid, nice clean spray pattern) and connectors and the green contacts on the injector itself. assembled them into the rail and laid the assembly on a towel on top of the motor. all 3 sprayed strong and in pattern. I thought of the related sensors and went ahead and reassembled the SC hoses in hopes that it would help.
Today, ill pull the valve cover and take a look, but if i have nearly equal compression on all 3 cylinders, jumped valve timing would cause different results on a compression test right?
I appreciate the assistance Mister Magoo, and keep it coming.....
Ive had alot of views on this and my other post , Ya'll dont be afraid to leave a comment or suggestion, those are some of the best knowledge that cant be found in a book or manual.
