I was on my way to work this morning on my 1990 LWB and 1/4 mile from home the engine died. Brought it home, cranked it and nothing, it has fuel as I can hear the fuel pump running but it shows no spark.

I tested the coil per the FSM. Tested the primary coil resistance (from + to Hight voltage terminal the standard value calls for .72-.88 ohms I get .9ohms.

Then tested the secondary coil resistance. Standard value calls for 10.3-13.9 Kohms, I am getting 11.

Also tested the power transistor also per the FSM and it tested fine. Still went to the auto parts and got a new one and still no spark (they were nice to accept it back).

So, what now? the ECU is freshly rebuilt. What else could it be?

I cannot enjoy driving this thing.
