Hi,

I parked my 1990 3.0L V6 4-door 4WD Montero about 6 months ago. I charged up the battery and tried to start it. It cranks hard but won't turn over. I tested for spark and has none. Plug wires aren't new but newer. I swapped out for a new distributor cap & rotor, even though I didn't figure that was the problem they were cheap. I had the Ignition Control Unit tested at a local auto parts store. Tested fine. Swapped in a new ignition coil. Still no spark.

I'm looking for suggestions on what to try next. I have the Haynes manual and it isn't very helpful. Could the photo optic sensor be the problem? It ran just fine when I parked it.

Thanks much!
