Last time Cole had the fleet truck over, I looked, and it didn't look like the driver's side injector was spraying. WCJr originally had a TBI, and I'd bought a spare TBI from Pull-A-Part and did all the "mods" on it, including new big block injectors, but after all my dorking around with the TBIs, I didn't have a good fuel pressure regulator. I ordered a new fuel pressure regulator and injector top from RockAuto ($44, ugh) so I could swap my spare TBI right onto his truck.
Tuesday I got an email from RockAuto saying it had been delivered. I checked DHL, which directed me to the Post Office. They said it had been delivered, but no box. I submitted a mis-delivery over the phone because the Post Office's website sucks and doesn't work. They admitted fault and delivered the package today.
I got the TBI ready and Cole drove over to get some of his stuff. While he was packing stuff and carrying it out I swapped out the TBI - only to realize the '94 uses the round-plug TPS and my spare '89 TBI uses the flat-plug TPS. No problem, I'll just swap the TPS! Doh! They don't swap.
I ended up reusing his TBI, but swapping the injector pod. Then we discovered one of the flat plastic o-rings on the fuel inlets was missing. We jetted over to O'Reillys where everybody behind the counter swore up and down we didn't know what we were talking about and that we should just use o-rings. We finally got a TBI rebuild kit and pointed out the flat plastic o-rings, to which the manager said, "Huh, it looks like you're right." I paid $33 for a stinking o-ring. And a base gasket, because we realized his was missing a 1" section.
We got the TBI together and back on the motor. It ran better, but still with a lack of power and occasional backfire. I looked at the injector pods, and sure enough, the driver's injector still didn't look like it was spraying. I hooked my finger into the injector pod just to be sure, and no fuel.
WTF? That's a new injector pod and new injector connectors. I had Cole turn the key on while I probed the injector leads with my test light. No power to the driver's injector while the passenger's was just fine.
I cut back the injector connector wire, and the copper all looked clean and fresh. At the end there was no connectivity, but further back into the wire it was good. I nipped off the end of the wire and put a new connector on it. He fired the truck up and it sounded like a real V8 and not a sick puppy.
He took it for a test drive and scared himself - plenty of power and weak brakes. It's still not 100% right, but it's more drivable than it was.
