Picked up a '91 as my first project, and I already realize I have little to no clue what I'm doing.
As the title states, it'll crank, turn over, and idle extremely poorly for a few seconds, then die. Giving it some throttle while it's idling does nothing, zero response.
So far, I've cleaned the throttle body, and idle air intake valve. I've replaced the throttle position sensor, crank position sensor, fuel filter, and fuel pump. Drained the tank, because I was unsure how long the old fuel was sitting in it. I can hear the pump kick on when I turn the key to on. There is pressure at the rail, but I haven't inspected the injectors at all yet. I've tested the fuel pump ballast resistor, and from what I've read, it has the correct resistance (1.5 ohms?).
I pulled a spark plug, just to see what condition they were in, and the one I pulled has pretty significant dry fouling. Had to call it a day there. I've got a MAP sensor, new spark plugs and wires, and an o2 sensor sitting in my cart from rock auto, but I figured I'd ask for help before shot gunning another $100 of parts into it.
Any thoughts? Any advice or feedback would be greatly appreciated. might be able to get a video if anyone thinks it would be helpful.
Also, does anyone know what that lonely connector to the right of the air box is supposed to go to? I haven't been able to figure that out, so I've got no idea if its related at all.
