I have an 86 SC that's not running. It cranks but won't turn over. With the ignition in the on position the fuel pump won't make any noise neither will any relays or solenoids make any noise. However jumping the db/yl pin on the service connector starts the pump but I must not be getting spark since it's still not starting.
The car won't give me any codes either, not even 55 which is supposed to appear no matter what, making me think it was a problem with the ecu (which is a Mopar stage 2). I tried replacing the ecu with a stock one, as well as changing out the power module to no effect.
I've consulted the electrical part of MiniMopar and have tested everything it states and basically he's saying it's the Ignition Reference Sensor (aka HEP right?). But the thing is if that's the case would I still not be able to get codes at all? Where is the HEP even located?
Could this be just one loose/broken wire that needs to be replaced?
tl;dr: No spark, fuel (pump does work), or codes (not even 55)
