Typhoon will not read codes - Please Help!!

[flywithmike]

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.

Re: Typhoon will not read codes - Please Help!!

Sounds to me like an intermittnet wiring / connector problem but could be many other things well. If won't read codes at the time of the no start, that is because the E.C.M. is "disconnected / not reading". Do the wiggle test, check all your connections etc. and just track it down. If it's an overheat / bad E.C.M., replacemet / substitution the only way to diagnose the problem.
