85.5 944 Injection question
I am battling a no start with my 85.5 944. No fuel, failed noid light test(valid???) good spark, fuel pressure, tried some 14.6 ohm injectors(thought they were 2.4)....wondering if I damaged the dme doing that?? Am going to put a scope on the sensors next check if they are “really” good since they passed static resistance and dynamic voltage tests. If sensors pass with the scope the dme will be next for service or replacement. Best place to send for service on the dme??? Anyone know if the Rogue Ecu is sequential type ????

high impedance injectors should be fine on stock DME, just not the other way around.
see this for sensor test
Rogue isn't really in business anymore, some folks have used ECU Doctors to recondition their original DME or you can find a used spare.

I have just found a dead short on one injector lead. In my haste I forgot to tape solder joints, and shrunk wrapped two wires together. I checked harnes with DME unplugged, checked okay. I checked for injector pulse, and believe that having attempted to start with a short, I have damaged the injector driver. Is this a likely effect of a dead short on one injector lead???
