I have a no start condition and the computer reads "COMM ERROR" The tech assistance on their site seems non existent I sent an e mail and I'm waiting to hear from them.

Generally, if I remember, I had to run dedicated wires for the direct connection for power and ground. Everything in the vehicle is useless. Also had a lot of trouble finding a good keyed 12v wire.....An MSD system can muddy up the signal as well....keep it away from that.

Check with a voltmeter on Ohm setting and see where you have the highest resistance. If all that is good, check positive wires with a test light and wiggle them while testing. If all my bad advice fails....Call Rich at FastManEFI on here.... Last edited by Dragula; 09/21/17 11:01 PM.

As stated before, check powers and grounds, but also check anything relative to buss network wiring. Anything that will stop any talking to the rest of the system (ie: throttle bodies) should be suspect. After that, it is usually an internal controller failure. Note: This is all my opinion from my experience as a Level 3 Chrysler Tech and shop foreman. [image][/image]
