Default What next? New ECM suggestions?

I have a 2002 RKC that has Rinehart dual exhaust, SE air cleaner and a power commander. She has been inoperable for about 3 weeks. She was intermittently cutting out/off. I took her to a local shop after looking for the problem for a week. The Indy found a broken ground wire that had to be tied into the ignition system or power commander as the power commander and fuel pump was dead until we reconnected the ground wire. Now the power commander comes on and the fuel pump primes but she still has no spark. We also replaced the Crank Position Sensor but no change. I am borrowing a friends ECM from a 2004 RKC tomorrow and hope to find out if that is it. Any other suggestions? If the ECM is bad should I replace it with a stock ECM?
Ride safe,
Mike

Also. I have a friend with a 2004 RKC with fuel injection like mine... Can I use his ECM to see if mine is bad? Or is an ECM married to the bike it is on?
Thanks!
Ride safe,
Mike

+1

you can put any ecm in and it will start then stall after about 2 sec.

but if it does start u know that your ecm in no good.

my bet is on the PC though.

Default Check security module

If you have a security system, check that. My 2002 RK had the same issue and it was the security module.

It seems to be working. I can still arm it and disarm it...? Unless you know more. Thanks for the reply.

Finale! I went back to my Indy today with a friends ECM in hand. With my friends ECM installed my bike would crank but only run for about 2 seconds. Removed his ECM and replaced it with mine. Now we are riding again! The problem was the broken ground wire and a bad crank position sensor. Fairly inexpensive to fix...
Ride safe,
Mike
