2001 jeep gc Laredo stalls while driving the rpm's go from 2 down to zero jeep still has electricity but dies after sitting about 10 minutes will start again already have replaced the fuel pump.?

Answer 1

CPS STANDS FOR CRANKSHAFT POSITION SENSOR

I had the exact same problem with my 2000 Jeep GC laredo, for several months. I could never predict when it would happen. Then more frequent problems with "won't start, though engine turns over", then wait a few minutes and it starts. I just resolved it two weeks ago by changing the CPS (Crankcase Position Sensor). I got the tip last month by looking at other sites on the internet. There were several tips to "try replacing the CPS first". I asked my auto mechanic son-in-law about this, and he said he hadn't thought about the CPS, but it made sense as a possibility. This is a fairly cheap fix (about $30 for the sensor) -- it is a small plug-in wire with a sensor at the engine. My son-in-law bought the part at an auto parts store, and replaced it for me with a ratchet wrench with a long extension -- it is held in place with one screw. I have discovered that a failing Crankcase Sensor will cause exactly what you are experiencing. It could be several other things, but I'd suggest trying the CPS first. Hope this helps. Ron in PA
