Re: Merc 5.7L Keeps Dying

I appreciate it John and thanks. And yes they are pricey, but I just want this thing running! My old deadline was June 2nd, now I want it done by May 19th. All left to do is upholstery, rub rail, and stereo.

Since you mention timing issues, just the other day I had hooked the timing light up to quadruple check the timing and noticed the mark I had made at 10 btc was jumping around. Almost like a tick-tock motion but faster. Just sayin in case that would indicate a bad ICM. It had a new sensor on it when it was doing that too.

That sounds like normat T5 ignition when it is not in base mode.

Re: Merc 5.7L Keeps Dying

Got the new module in today and the motor is now ALIVE! Ran beautifully all day. I also got the shift cable adjusted and its shifting good. Although its making a sort of clank when it shifts. Got some in and out play on the prop shaft but I figure its normal to have some.

A big thank you to everyone that helped me!

Congrats on doing that work yourself! Nothing much better than fixing a problem on your own....
