Help ASAP!

Post by gt2.5turbo »

So for some reason on my 2.2 turbo i dont get spark on 1 and 2 but do on 3 and 4. Car wont start just keeps turning over and backfiring occasionally. Got fuel... timing is correct... Switched out multiple coil packs and ignitors. Its not the plugs or the plug wires cause ive tested them. Im going back outside to check the wiring. anyone ever have this problem or is there anything else i forgot to check? At first i thought maybe cam or crank sensor but then why would i not receive spark on 1 and 2 but 3 and 4 all day long?

PLEASE HELP!!!

have you cleaned up the place where the coil pack mounts? iirc this is how the coilpack gets ground.

my initial thought was that you had a bad coilpack but if you've tried others that's unlikely...
yo mang, can I get a rootshell?
