I've wired my car exactly to this spec. but for some reason i cannot get my injectors to fire. I've tried everything i know of, looked for grounds loose grounds go over the harness multiple times, redone solders. i can even ground the injector and it will fire.the injectors are getting constant 12v too. i just cannot figure this one out. its like the ecu is just not telling the to fire or better yet not grounding them to make them fire.

Are you getting spark? Have you got ground wiht 0Ohms resistance to battery negative at pins 39, 48, 107, 108 and 116? If yes to all, dud ecu.

[ultimateirving]

have you opened the ecu up? its not uncommon for someone to have shorted them out down the line

forgot to mention that im getting spark from all spark plugs. everything is working on the harness except the injectors. its a jim wolf technology ecu. the car will run on starter fluid sprayed into the manifold. i haven't opened the ecu up but it was good when i pulled it from the car a few months ago and i don't believe its burnt up.

Put a stock ecu on if it still don't fire the ur issue is going to be in the harness for sure
Check the cas pin out y they don't fire would b cuz injectors are not getting signal from cas cas rotate injectors fire coil packs fire

The cas is firing the coil packs . The car will run if I spray starter fluid in the intake manifold. I'll try a diff ecu. The cas seems to be getting the correct power and seems to be working besides the injectors. There power to all injectors there just not being grounded by either the cas or the ecu. It's very wierd that everything is working but the injectors

Did you check the injector earths on the engine loom? 107 and 108.

Swap your cas and see

Its not weird. Obviously there is something wrong that u need to figure it out. It happened to me before and it turns out it was the cas
