No Spark
 

Ok so i believe i blew up my opti spark , but i want to get a a couple opinions to double check. I did a couple test and it came back weird. I have spark going into the Coil But no Spark coming out. I replaced the coil with another working one , and still the same results. Could it be that the optical sensor went bad and it doesnt know where it needs spark so its sending none ? Thanks

Could always check/replace the ICM. Its a lot cheaper and easier than the OPTI.

Checked it with the Coil.

First make sure the wires to the Opti and the Coil-to-Opti wire and in good condition and have no corrosion.

make sure you have fuel pressure. Also check the fuses. The ign fuse is located in the plastic box of fuses under the hood.

Next use the links below.

Opti Harness? Heard alot of people have issues with this as well.
