If you need dis-assembly or replacement instructions for any other auto/car part, or you want to ask question related to your car/truck jeep problem then please leave the comment with your details, so I can provide you the required instructions and solutions.
This is rare problem,but noticed by few Chevy users.The car will not start and has no spark,when the clutch is pushed the CLS /PCM fuse blows out.
That fuse that kept blowing is a direct wire to the PCM. Below is a picture of one of the connectors at the PCM. I have marked the pin number that you need to check. Make sure you're getting power at that pin number (it's a pink wire). Also below is a picture of a main ground for the circuit that the fuse was blowing. Also is a picture of the connector that that ground wire goes through. It's a black and white wire. Also I see you said you got a new computer. Did you have it or was it flashed for your vehicle ?
Sounds like pcm or wiring has a short causing fuse to blow. Maybe try another pcm.
You could also remove the alternator and have it bench tested at autozone or advance auto parts or your local auto parts store. This will tell you if the alternator is blown.This details will help.
Thanks.
