Camshaft position sensor 94 YJ 2.5L FI
I have been having trouble starting my Jeep after it sits for longer than a couple of hours. The check engine light has been on intermittently, and once I am able to get it started after several attempts of long cranking it runs fine. I can also turn it off after it has run, and it will start right back up. I used the check engine light method to extract the codes and 3 came out. the code numbers were 12, 33, and 54.
The 12 code was for loss of power to the PCM, the 33 was for the AC clutch fan relay (I don't have AC), and the 54 was for no camshaft signal detected during cranking.
What does that mean??? Is the camshaft position sensor going bad? Because after cranking it over for several 15-20 second attempts it will fire and if I step on the gas it will start.
Initially I thought it may be a fuel pump issue, but that doesn't make sense either because it will run fine after I get it started.
I can use all the help I can get. Thanks.
