1992 bonneville ssei starts, stalls then wont start
Don't change your PCM until you try the ICM like I suggested in my last post.
Ignition Control Module <--------The thing under the ignition coils. Check the connection.
Powertrain Control Module <------the main brain.
If you need either, I suggest a wrecking yard. The ICM can come from any 93-05 3800. (stay away from 92 as it was a mixed year, and the Magnavox ignition is ****, and go as new as you can get).

What it boils down to is that ONE code clearly identifies the ICM. We're very certain it'* a bad unit. Two other codes COULD be the ICM, but might not be. The ICM is the logical starting point.
Your TPS should be next, as the O2 won't prevent a start. But again, you may have a wiring problem or a ground issue, or a PCM fault. That'* a TON of codes to be throwing.
You might want to re-seat all your PCM connections to be on the safe side, and for some peace of mind. It'* above the right front passenger footwell. Remove the 3 screws that hold the hushpanel, and look up. It'* the silver box with the 4 connectors on it. You'll have to remove a 10mm hex to get it out, and it'* a tight fit and a struggle.
I don't have the time to look it up right now, but your spark reference, cam, crank, tps, and O2 may all use the same connector on the PCM.

well i checked the fuel pressure and that was fine... and it seems to start now when its cold... but after a few min. it stalls and wont start. i checked the MAF and it seems to have been tampered with at one point as there is teeth marks from some vise grips and the base of the sensor is cracked. Oh and i also cleaned the coils and ICM ( i think )
