S- 10 injector spray prob.....PLZ HELP

I have a 92 s-10 4x4 4.3 w/5-spd. The problem is it runs fairly good cold but when it warms up the fuel spray quits intermittently. After it warms up the injector stops spraying fuel. I have replaced fuel pump, sending unit, map sensor, tps, distributor, cap, wires, plugs, fuel filter, plugs, fuel pressure regulator diaphram, still dont know what the problem is.

well gussing its the ecm or injector itselfe

with the new map hooked up the fuel momentarly quits, but i now have it unhooked and it runs but not like it should

You know as stupid as this sounds have you put any fuel injector cleaner in?. You may also try changing the fuel injector as well. Not tryin to insult your intelligence but sometimes the simple things get overlooked.:2cents:

yes, have been thru about 3 bottles of inj cleaner. i even changed the distributor, cap, wires, everything i could think of, but nothing has worked, so far..

that much cleaner is hurting you, injector cleaners (and every other gas additive) contain patrolium distallets that will clog up injectors if used to much, we reccomend once every 6 months at the most for injector cleaner, and once every other for dry gas if you need it
