My situation is that my old motor's head gasket was blown and wasn't getting spark, so I dropped another motor from a 99/00 into my 95 and changed the dizzy ( tried 2 separate ones ) and changed my ecu still no spark any solutions?? Btw I'm running obd1 and my car is pure stock, also the engine cranks no problem and there is fuel

 

Its rare but likely that you have a wiring issue from the computer to the dizzy somewhere.

You will need to perform continuity checks on your wires. They may physically appear fine but may have been pinched somewhere and the copper is broken internally. This is not hard to do.... just get the correct wiring diagram for your car and a multimeter that does continuity checks.

Also check all the plugs where the harnesses are for corrosion and loose wires.
