95 S10 Blazer starting and running problems
I have a 95 S 10 blazer with a 4.3 motor. The problem I have is both a start and run issue. One time you try it it may start fine and idle fine for a few seconds, the next time it may not. The thing is even if it does start, the minute you put it in gear or turn heater or ac on it dies.I have put plugs, wires,rotor,cap, new fuelpump, fuel injector, fuel filter, egr, and map sensors on it. nothing helped. I was messing with it one day, I disconnected the map sensor and it started and ran at a idle, but still would die if a load was put on it. I tried another sensor, no change. I am lost, any ideas?
