I have an 88' toyota truck, and have experienced this no spark problem as well. It turned out to be the igniter. I found one at a local salvage yard insalled it then fired it right up. this could be something to check as well.

I had a similar problem. Mine turned out to be the large wiring connector under the drivers side kick panel above the fuse panel. The connector had worked partially out and a large white wire had arced and corroded to where it finally would not connect at all. When it made contact, truck ran fine. When it decided not to make contact, truck would die or not start or both.
I cut that wire out of the connector and re-connected it without going through the large connector and the rest of the wires in the connector were fine.
Solved the problem. Worth a shot. same symptoms.
Hope it helps.

I am not an expert but I have had this problem.
About the time your engine quit when you were driving did you hit a bump or go over a rough surface in the road? O my 91 4-runner near the Distributor cap (about to 8" away and close to where you pull the dipstick for oil or transmission fluid out is a small bracket holding a wire. On my car the bracket is broken. But after I hit a rough area and later stop the car it will not start until I jiggle this wire. Apparently there is a short there. But I have not found a replacement for the wire. I went through all the things that you did before I found this. I replace the igniter twice and once when I was stuck wired in a coil for a different year. Apparently I would eventually shake the wire enough to make connection again. Now I just shake the wire. I have glued it back in place a couple on times and this works for a while but eventually comes loose again. Probably due to the engine heat on the glue making it brittle.

I am a toyota tech. if the engine light is not coming on when you turn the key on, then a sensor is shorted to ground. The most common one to cause this is the Mass Air Flow that sits above your air filter. If you turn on the key and the engine light does not come one, first try unplugging the MAF and see if the light comes on.

I have a 1995 4runner with the same problem. No spark and I have replaced coil, igniter, dist cap, rotor, ecm, etc. I do have ck eng blinking steady when jumpered at test point.

Did you ever find the prblem on your truck? I have same problem and tried the same thing to fix. It is wierd that I was messing with the wires under the stearing column and the check engine light came on and it start for a few minute but went ou again.
