ok from what i understand c1 and c2 are going to the blue/green and blue/yellow wires coming out of the dizzy. what i dont understand is this: b10 is the crank angle sensor and b12 is also the crank angle sensor, but arent those already connected @ c1 and c2? to i wire them in series with c1 and c2? im very confused. right now im throwing a code 4.

 

Yeah i bileve the dpfi and mpfi ecu's have the crank angle in differnt locations on the ecu

c1 and c2 is the crank angle sensor location on the dpfi ecu, however on the mpfi ecu the crank angle sensor is located at pins b10 and b12. Hope this helps you out.

 

i can vouch for that b10 and b12

 

i fixed the problem, the guy who wired up my motor didnt swap wires orange and white c1 and c2 with b10 and b12 - thanks guys!!!
