I did a search for the problem, but could not find what I was looking for.
The problem I have is the engine intermittently shuts off while driving and when I try to start it back up, sometimes it will start, sometimes it won't. If I spray some starting fluid into the throttle body, it start back up right away and stays running. It also only develops about 8-10 psi of boost. I checked the boost soliniod and it's working. I have also repaced the fuel filter and cap and rotor.
The computer was showing a code 34, so I replaced the map sensor as well. I went for a drive after reseting the ECM and the engine died again when it came back to idle, so I check to see if it will give me a code and I got no check engine light flashing at all, not even the default code 12.
After spraying some starting fluid and driving it back home, I checked for a code again and this time it flashed a code 12. I seems to me that when the ECM is able to read codes the truck drives fine, but when I can't read codes, the engine will shut off and not start.
Anybody heard of this problem before?
Any ideas?
Thank in advance for any help.
