A while back my 86 fi x died near the house, it was acting like it was starving for fuel so i got it home changed filter which was over due, i added a pre pump filter and put in 4gal of non-ethanol gas and added two bottles of chev techron fi cleaner. it seemed to be running better but it occasionally would bog down and miss when i'd punch it.I drove it for about two months and it died again.So yesterday i checked the pressure going to the injectors at the port for the cold start injector. it was right on 36 and 28-30 when running, it would run for a while(3min)or so idling and reving a bit then die. seemed like it was starving for fuel again. when it would start it would miss and run rough for a while. Injectors seem to be clicking but i'm afraid that junk from the tank made it thru the old dirty filter and is clogging the injectors. since the fuel rail is above them..Anything that passed thru the nasty filter would drop to the injectors. I was thinking about using a bore scope and seeing if i could see a squirt into the cylinder thru the spark plug hole or do the injectors port into the intake manifold not the cylinder itself the rail is at 36lbs so if i energize the injector i was hoping to see a squirt to see if they were plugged or not. What voltage are the injectors? i used a meter but the voltage is so quick it couldn't get a voltage, just that it was going to the injector. i did check the timing and it was right on also i checked the belt to see if prehaps it has slipped but it was fine also....I'd appreciate any ideas if anyone has experienced anything like this....Was thinking about pulling injectors and having them rebuilt...who and where can i get the injectors worked on if necessary? thanks Gene
