2000 E320 Wagon CPS Keeps Acting Up
Someone please help. My Wagon is having CPS problems..I have changed Crankshaft Sensors three times in one day from discount sensors, too OEM and the same thing keeps happening.. It will start after it has sat for a few hours and run perfectly. When you shut it off it will not start until it sits for a few hours.....No malfunction Codes and the car runs perfectly when it wants too. What am I over looking??? Will resetting the ECU help??

Thanks OLord, I know they fail but not three in a few hours....Changed CPS three times in one day and the same failure accured with all three New CPS's.. Tech is now checking anything else but still cannot get any error codes so he is down to checking the harness....If anyone can think of something please help me out...Car has been in the shop for week and I need it back on the road.....

My post was
to clarify the misinformed total lack of correct information posted by Plutoe.
CPS fail most often without going code. The symptoms point towards the solution.
Your symptoms appear different than the typical hot run failure to start,cool start after 20 minutes cps failure.
m112 harness failure is very rare, and in the case of one it would throw a circuit malfunction of some item.

Anybody change the fuel filter?
Pressure regulator is built into the filter. Old filter can cause the issue and at times throw the codes normally associated with MAF failing.

Replaced fuel filter this morning only took 45 minutes, she started up with a little trouble but then started to run perfect....At least it started, rode around the neighbor hood awhile and parked it in the drive. Will go out in awhile and see if she starts right up....Thanks OLord maybe this will cure the lady...

Back to square one as of this morning.....Now it seems to be a fuel pump problem....When it does not want to start I don't hear the fuel pump go on....When it does start I hear the buzz of the fuel pump turning on when I turn the key....So going to give that a try....

After weeks of problems, the problem has been solved. A frayed wire connecting to the fuel pump was causing all the trouble...Found it while installing new fuel pump...Hope that this puts an end to all the troubles.....Thanks to everyone for all their input and hope that my troubles will help someone who is having the same problems.....
