go to this link for copy of 1993 FSM: http://personal.utulsa.edu/~nathan-b...fsm/index.html

Are you talking actual ECU pinout or the connection under the hood?

If it's the ECU pinout, you'll find it at this sub-heading: http://personal.utulsa.edu/~nathan-b.../6combinat.pdf

Looking for a pinout

Long story short, i have a 94 t100 m/t with the 3.0 3vze. It has a no start condition. After I reset the ecu by taking off the battery cable it will fire one time. It seems like it wants to start but continued cranking reveals it has no spark. UNTIL i take the cables off and reset ecm all over again. Then, same thing, hits once and doesn't spark after. I've completed every check/test i have found so far with the coil being the only thing i replaced due to out of spec readings. Got a new igniter and tried that, didn't help. Same problem. Vaf checks good. Even opened it up carefully and inspected it. All good. I was told it ran perfectly and then the fuel pump went out and was replaced. It ran fine after that. Then wouldn't start one day. Based on what I've read this is the place to help me figure out what im missing.

Were you ever able to figure this out? I'm having almost an identical issue myself
