Thanks to SIRMQC for the post on the crankshaft position sensor, his sage advise just saved me $1400. Own a 2001 Catera with 60+K miles. I've been through all the horror stories of buying new tires every 6 months because of uneven tire wear, $4500 to fix the AC and others. It got to the point that I was telling the Cadillac folks what the problems were. Anyway the other day I'm driving down the interstate at 70+ when the car dies. Had it towed to the local shop and they thought it was a fuel pump relay. Car ran for about 45 minutes then quite. They gave up so had it towed to Cadillac dealership. Prognosis was bad fuel pump, $1400 dollars to replace. I read SIRMQCs post and gambeled it was the CPS and replaced it myself. Drove the car today and it appears fine. It is an easy fix as long as you don't try to route it behind the oil cooler lines which is what I believe causes this problem to begin with. I followed the advise of others and tied it off away from the exhaust manifold and just cut the connector off one end of the old one and pulled it out.
