spark

Go to the "Do it Yourself" site on our home page. Scroll down till you find the directions needed. NOTE: Is there power to the coil?

i put a new coil on and it worked for about 1/2 mile then
back to the same thing so spark to # 1 plug

Did you lose power to the coil?

i guess back to no spark to #1 wire just dont no why it work for about 1/2 mile then stoped

after checking it agian i guess iam not getting no power to the coil
#1 and #4 has no spark but after i put the new coil in they did for
about 1/2 mile but not now Hey and thank you for helping me

Okay, I need you to check the wiring to the coils. There could be a break in one of them and you make contact once in a while. Move them around when starting the vehicle.

Let me know.

wiring to the coils is ok

If you have power to the coil, the next check is the ignition module. It is in the distributor.

dont have a distributor.

Sorry... I was thinking they still had them in 87. The only other thing is either the crank sensor, a broken wire, or the PCM.

put a new coil on and a Ignition Module on and worked good for about 150 miles
now back to the same thing no spark to #1 and #4 plug not getting any thing to that coil why would the Ignition Module go bad agian
