Got everything installed, and powered, ('92 EJ22 in an 85 GL-10) the engine will start and run for about 15 - 20 seconds and then dies. Throttle causes it to die quicker. I have the fuel pump relay powered directly off the ignition switch so the pump comes on and stays on in crank and run. I have checked all vacuum connections. Swapped out known good MAF, TPS, IAC, crank position sensor, tried 2 different ECU's and made sure that the ECU gets a start signal from the ign. switch, checked all grounds, and added some redundant grounds to be sure. I was able to keep it running for longer by spraying starting fluid into the air intake tube, but nothing else seems to be presenting itself as a problem. Any help would be greatly appreciated.
