no spark problem

[classic69]

im having a no spark problem on my 1990 Eagle Talon AWD 5speed. i tested the ignition coil and ignition module both are good, seems to be getting no signal from ECU, i have a 1992 Eagle Talon AWD AUTO ECU that i use in my other DSM, would that ECU start up the '90 car? i read the compatibility list but it only mentions a different tach setup or something, also how do you test the ignition signal on an ecu, i think its pins 55 and 54? all help is appreciated thanks

Best to start with a 90' ecu. check your timing belt and make sure the cams are spinning when you crank it. Your cam angle sensor could be wasted too.
