so my boosted car has been sittin in the garage for about 2 months. Im running DSM 450's (black tops no blue) , a chipped P06 with vtec, and an obd2->obd1 harness. I went to start the car up with the p06, nothing. no fuel or spark. So i was curious today, and tried to start it with my stock p2p ecu, and it fired for about 3 sec with no CEL. So i think this narrows it down to the ecu or harness? anyone else ever have this problem?

This is gonna sound really stupid but there is a round on the harness that is held down by a 10mm screw near the Thermastate. Check that ground and see if it's loose. If it is tighten it down and watch the car start right up.
