My zz502 has me stumped. I had Eric rebuild the Holley and it performed excellent but it did not cure my problem. I then had F.A.S.T EFI installed (not cheap) and the issue is still present. The problem: it starts and runs fine from cold but after running up to temp and parking for a little while (20 - 30 minutes) it doesn’t want to start again and doesn’t want to idle. I have put in new plugs, ignition coil, plug wires and had the timing checked by the guy that installed the efi. What can cause this issue?
