Ok so yesterday I drive to work just fine no issues, I go to leave work and start my car it runs for litterally 1 second and dies. so i turn the key off and try it again same issue. I repeat this process a couple times and the same result. So I tow it in the shop and hook the jumper wire up to the OBD1 port and I am pulling a couple codes. So I check and I am pulling code 10 - Intake air temp, 11 - N/A and 20 which is ELC. So I reset the ECM and now all it is throwing is a code 10. I checked the resistance on the IAT and the voltage and ground on the wiring... everything checked good. So leaving the IAT unhooked I disconnect the jumper cable and turn the key off and reset the ecu. I got back in and the car started fine I plugged the IAT back in and drove home, I got back in it this morning and the same issue. The manual stated if everthing checked out fine with the IAT use a known good ECU and if it works with a new ECU replace the old ECU. My ECU is a P06 chipped to a P28 with an H22 base map, I have no O2 or EGR. Has anyone come across this issue?

Ok so I am going to update this as it goes, the past couple days my car was doing it's regular start run for two seconds and die routine until yesterday. My ECU is a P06 with a P28 chip and an H22A base map so i Don't read many of my sensors. Yesterday I was reading through the Prelude shop manual and thought my issue could be my PGMFI main relay causing it to run for 2 seconds and then die because the relay is two part. I went through the entire trouble shooting process and the relay checked out, I put everything back together and the damn thing fired right up last night and I could shut it off and it would keep firing. I went outside this morning thinking it wouldn't fire and sure as the sky is blue it did so I drove it back up to work. Now I am going to give it to one of the techs in the shop and see what he can figure out.
