I removed a 22re fuel injected engine from a 1989 pickup and put it in a 1990 pickup. Thought I labeled all wires. Everything went in great but the one wire I didn't label. Three brown wires on one eyelet connector under the intake manifold. Does it go to one of the two studs on the upper half of the manifold, where the two halves connect for a ground? Looks like that's the only place it could go. It's been months since I removed the engine and I just can't remember. Thanks, Scott
Intended to get back on here before now! Did get the truck going July 4th weedend. Started first crank, which it should have. I knew it was good but was hoping all wiring and install worked. The guy I got the truck from had a new header he was going to install if he had built the motor. So I put it on since I had it. It's a Pace Setter which from what I've read probably isn't the best, but maybe not the worse. Hey, it came with the truck and was new! Bolted it back to the cat. converter and ran great for about 225 miles. I had a new exhaust installed from front of the converter back, removed converter but kept the O2 sensor in place. That was around 165 miles. By the 225 mark, it would hardly run. Felt like it wasn't getting fuel and tail pipe was sucking back like a burned valve, and idled rough. Well, I had told my son as we were wiring the engine that since the truck had been sitting in a garage for 2 plus years, I was going to drop the gas tank and make sure it didn't have crap in it. Too anxious and skipped that step. May have been the beginning of the problem, maybe not. Dropped tank, removed fuel pump and it was rusted along with the inside of the tank. Had already removed the tank from the wrecked '89 so checked it and was clean as could be. Put it on, replaced fuel line from same truck, replaced fuel filter. Filter was full of rust. Still idles rough, hard to pull out in first gear but runs some better once it gets rolling with some rpm's. Did removing cat. converter screw up the O2 sensor? Could rust have made it past the fuel filter and plug an injector? Have been reading A LOT on this forum. Great information. Someone mentioned about the same thing I've done and about same problem I'm having and a suggestion was made to install an O2 Simulator in place of the Sensor. Also, check engine light came on and haven't had much luck reading codes. Screwed up and removed neg. post and cleared code last night. Need to drive some more till it comes on again and try for the codes. Sorry to have written a freakin book here but I figure from what I've read, someone out there has run into the same deal. Any suggestions are much appreciated.
if it were me id take the injectors to a shop and have them cleaned as well as the fuel rail. with the fuel rail off and filter off id blow compressed air though the system, starting at where the hose comes out of the tank. do the same with the fuel rail with the injectors out. i have had good luck with a gallon of gas in the tank and 1 can of berrymans b12 mixed in the gas to clean everything up though the o2 sensor should be fine
