most likely your distributor took a **** on you.

your car would run if the distributor is bad. trust me. i had a code nine and did the troubleshooting that used to work in the faq page and figured out my distributor was bad.

b10 and b12 are the cps right ? c1 and c2 are the cam anlge.


check to make sure those wires arent mixed up. and that the b10 and b12's are going to where they should.

Did you splice into the factory wire that was at b12? Or did you depin it and repin the new wire?

If you spliced into it, redo the wiring. That should fix the problem.

who made this "custom wiring harness" that could be your problem. its 10x's easier to do the wiring yourself.

Unless it's from rywire

But yes, knowing that it was done right would save a lot of hassle.

There's a good chance that any added wires for the 'new' sensor in the dizzy aren't good enough. I had to replace my wires twice, 1st time it just wouldn't work, 2nd it worked for a while (heavy-duty wires), 3rd I just got tired and ran 14ga stereo wire for them.

Honestly, keep double checking your wiring. You will find the problem.

Replacing the wire might be a good idea. What guage are the wires?

Good luck

hell yes!

its about 6 wires in the ECU side that need to be moved/ added
2 for the CPS
2 for te CAS
2 for the added injectors ( if you wanna be gangsta about it do all 4 straight from the ECU to the injectors.

engine bay is just the dizzy wires, Cam angle sensor wire and the injector box.
