I put a H22A in my 94 del sol. The engine cranks but won't start. I got spark, fuel pump is good, timing is good (TDC cams gear & cam shaft). I'm not sure if the injectors are firing. I'm getting power on the injector, i'll be checking if the ecu is sending ground and make the injector pulse (buying a noid light to test this). Also, i'll be checking the compression soon too. Any suggestion why it's not starting? All the wires are good, i've checked it 10times already. HELP!!!!
