fuel pump dead, but no code?
my car died on me the other day, it gets no fuel. pump doesnt prime when i put it in ACC.
thats all well and good, either a wiring problem or a bad pump. my problem is, when i hooked up my scan tool to it, or when i put the car in ACC without it plugged in, i get no service engine light at all. im almost positive it worked up until my fuel pump quit working. is it possible my ecm went bad, somehow not making that light come on, and giving no signal to the pump at the same time? can i check this to confirm or deny?
other than this, as far as i can tell there is no problem with the car.

Might want to check all your fuses and fusable links.Start there if all looks good you might check power to and from your ECM.If that looks good then inspect the SES bulb and see if its blown.
