ok so I have recently bought my first fiero.. 85 GT 45K on it 4 spd car. it sat for a while so I did distributor cap rotor plugs wires fuel filter drained all old gas out and refilled with super problem is 1,3,5 have spark but no fuel 2,4,6 run good have +12v key on engine off at wire at connector.. I change the ECU( reman 85 specific) per suggestion of a friend but still will not fire those cylinders.. the solder joints are good, injectors fire when pulled and 9v is applied with cleaner.. I have never spent so much time messing with a car with no results just becoming one with the engine.. what can or should I test or look for? All my grounds are good clean and tight.. fuel pressure is good compression is good.. the ground on the injector harness have continuity to ground.. I am at a total loss here..
HELP!!!!!!

Check your fuses? I think there is a fuse for each injector bank (side).

Check injector fuses

Welcome to the Forum! Are you aware of the INJ1 and INJ2 fuses? Each bank has a separate fuse, so there may be something wrong there. You can squeeze the tabs on the sides of the fuse box and swing it down for better vision.

Edit----------I came in Third in this race! gotta type faster!

I have checked both with a ohm meter both have continuity

Read through that link that Jaski provided....and look at Phonedawgz' post about backprobing.

OK JUST checked those wires I seem to have 12+ volts to both key on/off and key on/on but the car is running and only on 3 cylinders still...

I will get a tester like shown in a few posts and see if I am getting pulse but I don't belive so due to it running only on 246.. can be prom be bad?

seem to have fixed it I traced all wiring from ecm to injectors, checked pulse and I have it now.. now onto replacing the noisy waterpump( made knocking sounds) had me worried but took off the belt and its quiet as a mouse and engine runs smoothe and quiet now..

? You fixed it by looking at the wires? It may not be a permanent fix.

Agreed. A "jiggle the wires" fix may come undone after the next bump.
