The first thing to do is to find out whether the problem is fuel or spark related. Carry a spare spark plug with you so you can quickly pull a SP wire off the engine and slip it on the spare and lay the spare somewhere on the engine, NOT against any FI wiring harness parts. Grab a passerby to watch the plug for spark while you crank the engine with the starter. Get a voltmeter and connect it to the output side of the fuel pump relay. Place the voltmeter where you can glance at it when the engine is having trouble. You should read full system voltage (12.5- 14V any time the engine is running. Do you hear any relay clicks from under the dash when this happens? Have you tried cleaning the FI trigger points with a clean piece of paper? (Do NOT file them.) Check all the FI wires you can find and make sure their contacts are tight and that there are no wires falling apart. This has got to be exasperating for you, but you seem to be handling it well.
