Ej22 starts immediately dies

Recommended Posts

Hey guys! You all have been super helpful throught out my swap.1990 Ej22 into a 82 brat Tonight I was finally able to attempt a start and low and behold it will start. The problem is it won't run for any amount of time after I let off the ignition. All the vacuum hoses are hooked up well. I'm thinking possibly my wiring still. Any other ideas??

Make sure you have ignition power to the ECU, rather than just power when in the start position. 

Quick test: put ignition into ON position, check that the ECU has power/is on (CEL should be lit up too). 

My initial thought as I read your issue. 

Other one that caught me out is the IACV hose under the intake - make sure it’s connected. If not it will run for several seconds then stall.
