94 s-10 2.2L only runs on 3 & 4
My truck was a freebie mechanics special. I've replaced practically everything except the injectors so it seems like a safe bet. But they'd cost -/+ $100 so I want to ask for alternatives first. Another thread talked about checking the ecu on a '99 but I don't know if the diagnosis would apply to a '94. Has good spark, recently re-bored w/ new pistons, valve lifters work, runs just as good w/ 1 & 2 plug wires disconnected. lacks power.
! Do the injector wires go to relays or directly to the ecu? Maybe the wires? has anybody done this? Update: #2 had a plugged injector, #1 had an internally grounded (brand new) autolite sparkplug. Just so you know & now y'all can sleep at night & not worry about it. Last edited by Mous; 06-11-2018 at 03:26 AM. Reason: update |

This doesn't make sense since 1/4 and 2/3 are paired together....

Unless a cam is wiped.
