Drove the car for about 30 minutes today...parked it in the driveway while I did some cleaning.....went to move it back into the garage after 20 minutes or so and all it would do is crank.

Put my Scangauge II on it and there's the code. CPS is at fault. Waited another 30 minutes and it started right up. Perfect timing...it's going in for it's annual maintenance in about two weeks. Good thing I bought the warranty (Mercury) last year (zero deductible).

Took the beast in today to my Indy mechanic....Service B with brake fluid exchange and the CPS fault. All done on time and reasonable price. Mercury picked up the bill for the CPS parts and labor....zero deductible.:rockon:

When any product meets or exceeds what it claims then they get my :rb.....if they don't then they get my :tazz: and if they don't improve, then they get my :butt:

Simple.

Is it a good idea to replace the CPS anyway even if the problem has not occurred yet or should one wait until it happens first?

They fail due to heat as they age...if it happens, just wait about 20-30 minutes and it will turn right over. However, I would see it as a warning to get it replaced rather than just playing the wait game and hope it doesn't go tango uniform (TU).

fwiw, the very first symptom i had with mine was that it would turn over and not start. the waiting game yielded a start with ~2 miles driving distance before mine decided that it was finished.

in my exp., mb wont replace under warranty unless the part is faulty. not sure how much the part was since i had the work done under warranty

If it trips a CEL it's covered by warranty....one doesn't need to be stranded on the road for an intermittent CPS. I just snapped a photo of my Scan Gauge II screen and had it ready to show if for some reason the code is cleared by the computer.

the issue was the speed of events. the first indication of an issue was crank/no start. when it did start, the cel came on and i tried to get it home (only 2.5 miles away). the car gave up after 2 miles making it necessary for a tow and the ruining of friday night/ sat morn (to get a rental car).

it was towed to mb and diagnosed as the cps. it was replaced and i got the car back yesterday. i was thankful that there are posts on this topic. it helped me go from wtf is happening to oooh, i probably need a sensor replaced under warranty.
