Ignition Control Module 1990 S10 4.3
Hey all, I have a 1990 S10 Baja with 4.3 The truck sat for about a year and not runs like pure crap'o'la.
It's real hard to start, have to hold gas all the way to the floor and crank it over for quite a while, finally starts, stammers, spits black smoke.. finally revs up and sounds normal, idles super low and chunky then dies. You can drive it for about 5-10 mintues but once it gets hot it will puke and die and WILL NOT start again for atleast two hours (almost like it got really rich and flooded) It's Tbi and here's a list of all the things I have done to fix the problem.
New fuel pump
New fuel filter
New ignition relays
Checked all fuses
Changed oil (lots of gas in the oil!?!)
New PCV valve
Removed, inspected, cleaned EGR valve
Replaced cracked vacum lines
Replaced TBI injectors (no change here at all)
I got a parts truck it's a blazer with a smaller V6 (not the 4.3) I was gonna try to use the ignition control module from that or even the entire distributor if that's even possible.
Any thoughts??? Thanks much!
