I have a 1994 Toyota SR5 Pickup, 4x4, XCab, 3L 6cyl w/ 198,000km
Amonth ago, I added gas line anti freeze and feul injector cleaner to 2 tanks of feul. once in a while the engine seemed to run a bit ruff at idle and idle at around 500rpm instead of 800rpm. Here is the problem; every once in a while when I shut the engine down, and go to restart, it would not start at all, not even a kick! * If I left the truck for about 2 hours, it would start up like nothing happened* If I tried to start it any earlier, it would not start!
Just yesterday, I had the same problem, but there is no gas additive.

Any Ideas??
Thanks, Carl

 

sounds like a starter issue...Mine had similar symptoms when it went out...
