Re: Syclone ECU Communication Problem
Thanks for the responses. Our guy tried two scanners: a GM Tech 2 with an adapter for older cars, and a Verus snap-on. There was no communication at all; it powers up but it will not communicate. Don't know if I need a new ECU (only have 17,000 miles on the truck), but need to communicate to solve our problem of hard or non-existent starting despite strong battery (fuel pump issue?).

Re: Syclone ECU Communication Problem
The most common problem is one of the pins gets pushed out the back of the ALDL connector. You could also run a jumper from the ecm to the ALDL. Pin E12 looks like the one to jump from the ecm to terminal B on the ALDL. Terminal A on the ecm should be tested for a good ground.

Re: Syclone ECU Communication Problem
Jim's suggestion didn't work. Still no communication. We're using a GM Tech 2 with an adapter for older cars, and a Verus snap-on. There was no communication at all; it powers up but it will not communicate. Don't know if I need a new ECU (only have 17,000 miles on the truck), but need to communicate to solve our problem of truck not starting despite strong battery (fuel pump issue?). Any ideas at all?
