Runs for a second or two....

[SV&HOdan]

My showagon was stuck in the supermarket parking lot for a week while I tried different things. Car starts but cuts out after a second or two. No theft light
on and the fuel pump shut off is not shut off. any thoughts?

So you tested for fuel and you have fuel pressure at the rail? Is your battery fully charged? In the short amount of time that it does run, how is the alternator output? Does voltage increase or decrease in the short amount of time the car runs? Any codes?

Did you check the main computer wire to the battery? Without good connection it will show those symptoms

I know you said no theft light, but it still sounds similar to a PATS problem I had a few years back.
PATS module is more or less directly above your gas pedal, try unplugging and replugging it a few times, maybe a dirty connection?
