About 3 years ago I was turning left into my neighborhood and the car dies, starts back up and i get to my driveway and it dies again, wont start. The PCM fuse blew and since then has blown about 3 in the past 2-3 years. For the past 8 months i've been having a moving random misfire with the p050,p060 cylinders then moving to p030,p040 and now back to 5 and 6. Moved the COPs around made no difference, cylinder 4 actually cracked the plastic on the brand new plug. checked injector resistance and they all read the same. Compression test turned out ok for all cylinders. I get lack of s0211? switch cant remember the exact code and right bank lean codes but ive had that one for years. Ive checked all the vacuum lines going to the intake and none indicate leakage.
Then just recently the car started stalling out, hesitating falling on its face when i would turn left. lifting off the gas seemed to help but its been getting worse. the PATS system ------- flatlines and blew the PCM fuse 3 times trying to get out of my neighborhood and back. I'm thinking a short off the PCM fuse which I find out goes through the CCRM and powers all kinds of stuff. I had it on a jack and it would not start just popping the breaker i had in place of the fuse, trying to track down the culprit. All o2 sensors disconnected still popped it. MAF wires look good not too stressed, pulled the trunk apart looked at the fuel pump wires, messed with COP wires untwisted a few. After i dropped it off the jack it started so i've been driving around with the breaker in it. I pulled the ccrm out today but didn't test the relays.
If you didn't get bored and leave here are my questions. the wiring diagram indicates most of the systems powered through the ccrm are fused before it by 2 small 20amp fuses in the central module. The only other power wires go to the coils and the PCM itself. So if those fuses havn't blown the short must be from the coil power wires, correct? It would kinda make sense as turning left and throttle will torque the engine and nearby wires. Could the ccrm be at fault? Could the random moving misfires be related? Any advice would be great, the car has 180,000 miles i'd like to see 200k.
