in a weird problem here, yeasterday my car started doing this.
the car starts fine but stall right after. what happens is car goes high in rpm when started and when it idles down, i can hear 3 to 4 buzz fron fuel pump and it dies. anyone had this sort of problem before? was thinking it might be idle control but car will shut down even if i press on the throttle.
could it be fuelpump ecu? thanks all for help

could be or a bad fuel pump if u go to a shop they can put a fuel pressure gauge on the line and confirm 4 ya

it could do you have to jump start it? and also if the alt is not charging when it idles the bat light should come on. u said u put in a new pump? what kind of pump is it ? if it is a walboro u may have to unplug the fuel ecu and jump it i had to do this to mine it just kept killing the fp ecu and most guys i know who have installed that pump do the same.

thanks for your help...

how do i bypass the fuel pump ecu??? I was goig with the manual the other day and to jump ecu i am supposed to use diagnostic plug right???
my bad is that the stupid plug doesnt have pin for fuel pump in it....Weird
is there any other way of bypassing ecu?

also, anyone know if dealer can check our engine control unit? i took it out and want to know if is running good...
