hello everyone,

I have did a complete tune up on my truck and replaced the fuel filter and battery as well. Spark plugs, wires, rotor button, distributor cap, terminals, air filter, My truck will not start on and off. I dont know what is wrong with it and when i take it to the shop of course it starts right up. He checked the pressure and it was fine. It usually will not start after it has been sitting awhile. I bought some heet to put in it to see if maybe i got some bad gas. I checked the codes on my truck and the numbers were 11, 12, 32, 55. I am not sure if anyone else can help me out with this problem.
11 Timingbelt skipped 1 tooth or more from initial learned value, Intermittent loss of either camshaft or crankshaft position sensor, No crank reference signal detected during engine cranking
12 Direct battery input to PCM was disconnected within the last 50 key-on cycles
32 EGR system failure
55 End of error messages (If you get this only, no errors were found)

Please help me. All the techs are not finding the problem where do i start.

 

I bought my wife a 2000 jeep grand cherokee and it would die at stop sign's and red lights. Had the codes for intermittent loss of cam or crank sensor. After a new cam and crank sensor and a cpl months of tracing and pinning the entire wire harness i found the pcm was loosing the 5volt reference power for the pcm to keep the sensors synchronized. So i could synchronize the sensors and it would run great but if i shut it off for 10 mins and start it back up it ran like crap. I bought a pcm and problem solved. Not sure if that helps any but that was one experience ill never forget.

 

I was having a starting issue myself last year. Maybe what my issue was will be close to yours.

I'd go start the truck in the morning and I'd get a*CLICK* and I'd lose power in my gauges and radio momentarily. Now after a few tries I'd get er going and usually it was only after the truck had been sitting for more then 4-6 hours.
I replaced Plugs, Wires, Cap n rotor.
Well I eventually found out it was my starter cause it got stuck engaged one day with a mighty grind. Managed to get it home and replaced my starter the next day. Had no problems ever since.

Also just to throw this out here. Maybe your ignition switch?

 

#11 might just be it although you have a timing chain not a belt, could get a new sensor. also the pick-up in the distributor may also be going out????
