Hey guys, unfortunately I'm getting no fire to the coil. I'm hoping someone could help me out with my 1993 Dodge D150. This was my hometown's water truck & I would really like to get it running & fixed up! I've replaced the starter, alternator, battery, coil, crankshaft position sensor & the fuel pump relay fuse on the sidewall fender. The truck is turning over good, but getting no spark & no power to the coil. Does anyone have any suggestions ? Thank you for any and all help!

 

Need to see if the asd relay is coming on, If not it could be a pcm problem/bad relay. Does the check engine light come on with the ignition on? Any codes?

 

First of all, thank you Moparite for responding! Yes, the ASD relay is coming on. Unfortunately, the check engine light does not come on, so I can't pull any codes.

 

Try the key trick. Not sure if it'll work for you, but, worth a shot.... Cycle the key on, off, on, off, on. Then leave it one. The cel should blink codes at you. However, as your lite doesn't come on at all....... my guess is, that won't work either.

But, the ASD relay is tripping.... it should remain engaged for about 3 seconds, and the disengage, unless the PCM sees the engine turning. Of course, if the ASD engages, you should see power at the coil while it's on, and hear the fuel pump run as well. Do you??

 

Yes, I've tried the key trick, but not getting a check engine light to come on to be able to read any codes. Yes, I can hear the fuel pump kick on, but still getting no power to the coil. Thank you so much for any and all help with this!

 

You only have power for a few seconds..... takes two people to test properly. (or, a test light you can put where you can see it.) Verify you are not EVER getting power to the coil.

 

Yes, unfortunately, I'm not getting any power to the coil. I purchased a new ASD relay today & will replace tomorrow. Will update any new information I have.

 

I replaced the ASD relay this morning, but still getting no power to coil. Truck is turning over great, but still no spark.

 

I'd bet on the distributor pick up.

 

93 Should be a magnum engine, with the kegger intake, innit? Is the ASD relay actually being turned on? Is there power on pin 30?
