1995 Chevy Truck V8 Four Wheel Drive Automatic a lot miles
I have a 1993 Mark III Chevy 1500 and I love it. The original truck has a lot of miles but the motor has less than 50k.
Just recently it stalled out one day and has had issues ever since. Initially I assumed Cap and Rotor due to no spark.
Fixed the truck left it at my wifes work for her to drive home 1: 30pm. At 3: 30pm the truck wouldn't start at all.
The very next day I noticed the TBI wasn't getting any fuel so I replaced the fuel filter and again the truck ran and drove for over an hour before I parked it and left it at my wifes work again. Both times I drove the truck for 30-45 min stopping, parking shutting the engine off and restarting the engine with out any problems at all. This time it was 3pm when I left the truck in good working order 3: 30 it wouldn't start. AGAIN!
The third day of the truck sitting at my wifes work I go in to check it out. Again. It works fine at 9: 30 am starts runs drives.
I met her for lunch 12: 30 truck will not start. Gave it a shot of ether in the carb it started up. SWEET! Dropped the fuel tank replaced the fuel pump. It's all good to go or so I thought. I was finished before her next break we talked and before I left to go back home AGAIN the truck will not start.
Basically the issue is sometimes no spark, sometimes no fuel, sometimes everything works fine and then back to no fuel/spark at all. I am lost dumbfounded and baffled.
Running Diagnostics I get the following error codes
12 = PCM did not receive distributor reference pulses for 4 seconds. Or Diagnostic mode I am unsure. The vehicle is 305 with g vin but the first makes sense
67 = Cruise control Set/Coast or Resume/Accel switch was closed for 10 minutes.
I am stuck when it comes to trying to troubleshoot these codes other than looking for loose wires.
(81-82) my starter burned up during this process. OMG
Sorry about all of the info, trying to be as thorough as possible. And was hoping maybe somehow I was looking at this the entire wrong way.
Any sort of advice including how to troubleshoot the above codes would be great TY
Inside DIST is ignition module if it sends no reference signal to ECM no fire or injector pulse. NAPA can check module but is intermittent so may check good. Have fought this problem MOD not to expensive worth a try and save you all those trips to parking lot.
Let me know
