JeePete you know your stuff.

I did the on off on off on method.
I got code 12 33 and 55 thats all.
But I could not read the codes until
after I got the Jeep started and then
shut it back off. Before that I got
no fuel pump noise or check engine.

So there must be no power going to the ECM until
after the delay. Do you think it may be the ignition
switch? But why does it work fine after the first start.
I would think if it was the switch it would be a more constant problem.

Again thanks for the help.
