Hello guys
I went away on vacation for 2 weeks, had the master switch off. I went to start it today cranks but wont fire. I tightened the cables still no run. It will rattle with a little either. Any suggestion please. I see it is a message for the ecm

Smack the ECM with a screwdriver handle while someone tries to start... Also, there should be a separate power wire to it with an inline fuse, check that too.

is the electric fuel pump running when you turn the keyswitch on?
