Well, we heard it run today… kinda. Apparently, the ECU won’t turn on the injectors, despite everything else being set up and connected properly (fuel sump and fuel rails both are loaded up with fuel, so the pumps are working fine). The only thing I can think of is the ECU’s IGN wire needs a different power source – we plugged it into the big red wire on the leftover Duraspark 2-prong plug (tested good for key power), but maybe it’s not on for both ‘On’ and ‘Cranking,’ or is somehow tied to the Coil+ (which the instructions say not to use the same power as the coil – probably because of potential voltage drop).
We heard it run (kinda) because Dave suggested dumping some fuel down the throat to make sure it would even run if the fuel system would let it… and it did… or at least it tried. So, fingers crossed we can get the ECU happy enough to grace us with working injectors by finding a different key-power source that won’t have any weirdness associated with them.
The only pic I would’ve posted for today would be me giving the Jeep ‘The Finger’ on many occasions, which we didn’t get any (probably for the better).
