Car Notes: 1993 A9L computer, 19lb stock yellow injectors, stock MAF, 5.0 Freshly Rebuilt 306 engine
Some background to the situation:
Around 2 weeks ago I finally tracked my no fuel condition down to faulty capacitors in my A9L computer. Re-soldered new capacitors onto the board and truck now had fuel. It started up and warmed up pretty normally, but i couldn't drive it due to the driveshaft being fixed. Fast forward a few days, put the driveshaft on the truck and truck is back to no start condition. I spent a few days retiming and double checking everything, still couldn't get it to idle.
Yesterday I unplugged the negative terminal for about an hour, pulled all plugs( they were all fairly black ) cleaned them and put them back, then double checked wires. Used an endoscope to locate TDC on the correct stroke, and it still aligned with 0 on my balancer. Dropped the distributor in and aligned the 1st plug with the rotor. Unplugged the spout and cranked it. Would barely sputter. Advanced it to 14 degrees, it would fire but it couldn't keep itself alive. 20 degrees below top dead center, starting to sound like its firing all 8 in time but wont stay alive. In the end i moved the distributor to 35 degrees BTDC, it was firing all 8 sequentially and was able to idle reasonable around 1000 RPM. Got it to operating temperature and re-plugged the spout connector. Though when i go to drive it, it will drive pretty well if you dont go WOT, but if you do it will fall flat on its face. I haven't heard any pinging, only popping out of the exhaust sometimes
I just had this truck drive 500 no issue miles but all the sudden all of this crap is happening. Any feedback is appreciated, I'm trying to cover all my bases here so i can give enough information to solve the problem. When the spout is plugged in, i cant even read a number because its to far advanced on the balancer. My timing chain is brand new and aligned correctly. When i tried to set it back down to 14 degrees BTDC at operating temp, it just stalled itself. My only guess is my injector and MAF aren't calibrated for some reason. I know the steps to a base idle reset but that wont really help with the timing. The picture is of plugs 1 and 5 after a drive.
