I am a new owner of a 2005 limited roadster convertible.
I test drove the car before I got it and had no problems. The owner said the battery may be bad and he has had problems starting it sometimes. I don't think he or I knew what the real issues were.
I bought the car and drove it about 40 miles with no issues and went directly to get a new battery, so I wouldn't have any problems.
I put in the new battery, then the car won't start. Turns over but no start.
I had previously been on here and read about the CPS problem. So I decided to go eat dinner and let the car cool down. After about 1.5 hours I tried to start it again, no go.
Walked home. Went back to the car a few hours later and it started right up.
Parked it in my spot and planned on getting a CPS in the morning.
I did read about the Bosch CPS but wanted to get it started now. Bought a CPS from Advanced Auto Parts because they had one in stock.
Installed it with no problems, thanks to the forums.
Started up no problem, 5 more times. Decided to take it out, got about a block and engine dies. Got lucky, it started again and I turned right back around and made it back.
So I go back to the forums, read about the RCM and reflow the solder joints on the RCM.
Same thing, starts a bunch of times, then decides to die if I even move it.
I start it, push on the wire to the connector on the CPS and it dies. I do this multiple times with the same results and now I think I have found the real issue, the connector or wire. I know this is gonna be a headache. I do more research on the forums.
I read more on the Bosch CPS and someone mentions the pins probably being thicker. I give the CPS one more try. This time I bend the pins slightly just to see if it's the CPS or the connector. Connector feels real tight now.
Car fires up fine now and it's been two days. But I'm still praying that the issue is fixed.
I think my original problem was the CPS and the issue would have been taken care of had I purchased the Bosch CPS.
Can somebody with a Bosch and other brand CPS measure the pins with a micrometer and see if there is a difference?
Thank you everyone for their information that they posted here. It made my repair a lot cheaper, $38 and my free labor.
