I have a 1991 Eagle Talon ESI Thats been freshly rebuilt about 150miles ago.
i've been trying to sell the car so it hasn't been driven all to much. Well i go to start it up and nothing. it ran fine before i parked it. I have no ignition and i do believe the fuel pump is not turning on. I have ground to all ignition componets but no voltage were i'm suppose to( crank / cam positioning sensor). I checked the coil for resistence and it checked out good. All the Wiring diagrams point to the ECM(shitty haynes manuals). I'd rather not buy a ecm and was wondering what else it could be?

 

Does it just crank or do nothing ? Most wiring diagrams do point to the ecm. The ecm relay also controls the fuel pump.

 

yes it cranks but no spark and he plugs are dry so i'm guessing no fuel. Could you elaborate on the relays?? the book doesn't mention it

 

Anything guys i need this to run

 

still doesnt run

 

DSMs of that time period were notorious for capacitor failures inside the ECU. Get someone who knows about DSMs to take a look inside the ECU for you, and test a few things if they know what they're looking for. If I remember correctly, some say the caps can be replaced and the ECU will work fine, other people say it will destroy the ECU. I don't know for sure, I just remember hearing about this during my ECU hacking travels.

Google to the rescue: http://www.90gsx.com/eclipse/cap/caps.htm

 

Yea, its always good to check your caps on the ECU. If the problem is this bad though you can usually smell it or you will hear a clicking from the area. Its also usually fixable.

 

Do you believe th ecm is the only thing that could be bad???

 

It's possible. If the ECU isn't working, the engine isn't doing anything.
