Would a bad crankshaft position sensor cause my fuel pump not to run when the key is turned forward? I jumped the number 30 an 87 pins in the PDC and I can hear it run. I was just wondering because I have a no spark issue and was going to replace the CPS/CKP today after work. Btw, I have big hands and an older jeep that's gutted so I just cut out the area around it and plan to fab a small square or circle with thumb screws for future maintenance. Ha!
