Where to start?

Question

Ok, fighting this thing for months. I bought a new module, programmed it, installed it, get the same no start as I did with old unit. I took the new one and reset. Reprogram and tried again and still nothing. I can't even get it to allow me to program the remotes to test the start function. So pulled it out, put the old one in and it tried to start after I pulled the OBD wire. Plugged it in and it started and ran for a few minutes and I tested everything. Great it works again...next morning, doesn't work. Single light flash and nothing. I started it with the key, did a remote start transfer and it took over. I pulled the key out and it stayed running for about a minute, then stopped. I tried again, nothing. So after 8 hours, I tried to remote start and it did, ran for about 10 seconds and shutdown. What's going on? Do I have a wire gremlin on the vehicle side? I disconnected all the harnesses wires, plugged them all back in and still nothing. Is there an alternative wiring?

Hello,

- What is the vehicle?

- What is installed?

- What is the s/n to the module?

 

Best regards.

2004 Chevy Suburban. EVO One with RFK441, S/N isn't available at the moment as it is in the dash, covered, but I can get it out. It worked fine for 3 years, then just started doing this.

I would start by resetting and re programming the unit to the truck.

Reset the unit several times. Here's some more interesting info...the valet button doesn't do anything. I've replaced the valet button as well as just touched the wires together and still nothing. So doing a complete 23 reset is not possible.

Today I figured I would rewire the 6 pin harness, to eliminate the t connectors. No change.

It goes thru the start sequence, clicks once and then just like the key was turned off. It will act like it does a remote take over as well. When running, if I press to "leave" the vehicle but have it stay running, it clicks like it's ready. As soon as I turn the key it shuts down. It's getting cold and dark and I have maybe a few hours on weekends to try to figure this all out.

I have uploaded a video on YouTube.
