Hello All;

I'm new here.  I have had the 82 Collectors Edition since new.  It had been running fine... until it wasn't.  I have fuel and spark (and of course air) but no fuel to throttle bodies vie the key.  When I bypass the key, fuel is delivered to the TB's.  I have replaced the fuel pump relay (fun job getting to it) but no change.  I was thinking maybe the ECM powers the fuel pump but not sure, and can't seem to get any indications its working.  Any thoughts ???

Have you checked the fuel pressure to see if the pump is working?

Hi Larry! When you turn the to the run position do you hear the pump run for three seconds? If not Check for a fused wire going to the fuel pump relay and make sure the fuse is good and the connection are clean. The wire is in the battery box, connected to the positive battery block and goes to the relay, I do believe! 🤓
