i tried swapping the asd relays with a couple of other ones and nothing. I checked the asd circuit and im getting power to 3 of the 4 connectors for the relay so that should be good. I checked my connections at he PCM and its all good so it has to be the pcm.

 

Check schematics. Something else may be the issue. Don't just chunk the PCM.....not yet...

 

the coil pack appears to get power directly from the ecu. it was firing one sec then nothing.

 

Coil could be weak tho. Is the coil getting power?

 

After closer review I am slightly confused but I think I am getting closer to a difinite answer.

 

What's the answer you are thinking of?

 

Coil receives power directly from asd relay and ground from pcm. I will check the asd circuit tomorrow, which receives power directly from battery afte going through a 30amp fuse. Asd also receives power from ignition switch durin run and start. Looks like asd relay only controls fuel pump relay and coil. I am getting power to the fuel pump so the asf circuit must be working.

So to sum it up im not receiving a signal ground from the pcm to fire the coil. I will verify tomorrow.

 

 

got it all fixed. shorted wires were to blame. and a faulty dizzy cap. runs like a dream now. too bad i lost the key.

 

inquiring minds want to know, which wires were shorting?
