Starting problems with '89 Toyota pick up.
It will start for a week or so (30 to 40 start cycles with NO trouble starting) then it will hesitate to start for a fraction of a second and start. Then, on the next start attempt it will not start, this is associated with a clicking sound from under the hood when trying to engage the starter. This sound is not the sound associated with a weak battery, but a single click when I move the key to the “start” position or release pressure from the clutch while the key is engaged. I will let it sit for a period of time (30 mins to an hour) then the truck will start/turnover after a prolonged cranking period (6 to 12 seconds) and smoke will come from the tail pipe. I believe the engine floods as the cold start fuel injector still pumps fuel. It seems there is no spark, but intermittent starting in predictable periods and cycles are puzzling. Your thoughts?
