Back story. Had issues with TBI, rebuilt. Had some starting problems after truck sat for 1 day or more, but would start after a few tries. At one point when it was particularly stubborn, starter lead vibrated off. Once reconnected, truck started, ran fine, but had some electrical humming & radio interference. The starting issue continued with some low rpm stumbling, when driving check engine light would come on at cruising speeds and go off 7-8 seconds after letting off gas. Had 1 day lest week when I drove a bit more then normal (150+) but ran fine other then engine light. Next day started, but ran horribly rough with violent back fires. At one point stalled and would not restart. It looked and acted like it was flooding itself out and poor spark. Less then a year I replaced cap, rotor and coil. Now I have done all new plugs and wires. Now it appears I have no spark. I had been in the dash messing with the blower motor relay 2 days prior to the stalling and not starting.
Does the ECM control spark? Cant it go bad slowly? And if I had to do alot of cranking of the engine to get it to start, would that have any thing to do with it going bad?
I am no mechanic, but I did stay at a Holiday Inn suites recently.
