New to Toyota and now I have a huge problem. Main fuse blew somehow and replaced 80 amp fuse. Now truck still wont start. No spark from coil. Checked coil; seems good. New pick up in distributor still no fire. Junk yard Igniter assembly and still no fire. Please help, I herd this was the best engine toyota ever built, now I cant use the darn thing.

Thanks for any reply.

Let's start off with the basics.

"No spark from coil. Checked coil; seems good."

How did you check the coil? And then, how did you determine there is no spark from the coil?

And more important, why did an 80A fuseable link blow ???

Still having trouble.

sorry, I go to school full time and I have not had a chance to mess with the problem.

Ok, I replaced the coil same problem, I replaced the pick up in the distributor, I have tried a junk ignition assembly, and still no spark.

You asked an important question: I don't know why the fuse blew. I do know that the key was left in the ignition with the lights on for a while. If there is anything else; my son is not telling me.

Am I starting in the wrong place? I also downloaded a manual on a 87 p/u and went through the trouble shooting section to test the coil. VOM reads everything the manual says it should. Of course I could have done the test wrong.

Is there a better place to start my trouble shooting?

Held the wire to metal while trying to start...

speaking of basics....is the distributor rotor spinning?? I broke a chain one time. You should have 12volts on one side of the coil, the igniter(electronic ignition) breaks the negative side of the coil to produce a spark. Hope that helps.
