Those that have swapped in stock TPI or an aftermarket setup that runs each bank of injectors on their own fuse. (two power wires/fuses for injectors, total) Problem is that typically when the engine is started one time (sometimes not even one start) it won't restart. Not getting injector pulses when it won't start, but it is getting spark. I "figured out" my problem: too much voltage loss when the engine is cranking. All TPI stuff is run off the fuse panel accessory terminals, and each into it's individual fuse...as close to stock as possible. Already cleaned up/inspected all the ignition related wiring connections from the distributor to the ECM, no change. Had the battery tested, because the engine just won't crank much before the battery gives up, but of course they said it was good. Checked voltage at the injector fuse when it was cranking, it was dipping down into the 8's intially (volts) then into the low 9's. Went ahead and ran a wire directly from the battery into the cab, fused two leads and connected those to the injector wires. Voila, starts when hot. Checked voltage to the injectors when it was cranking like this, and it was in the 9.5V range briefly, then went into the 10's. None of the other terminals on the fuse panel read any better when it's cranking. Went ahead and pulled the fusible link ends from the junction block on the firewall, cleaned them all up, but that didn't help either of course. (but they needed it) When running or off, the difference in voltage from the battery to the injector feeds is almost nothing. I'm curious how everyone else ran their injector power feeds, that may be different than my setup. I'm going to go look at the wiring diagram, and look into the ignition switch. Expecting that I am seeing this problem partially because the ignition switch isn't getting a real good contact, but I've gotta pull the steering column anyways. I know what I need to fix, now I've got to figure out how.
