2005 Pontiac Grand Am No Crank No Start No Fuel.


Asked by Sep 16, 2016 at 02:48 AM about the 2005 Pontiac Grand Am GT Coupe

Question type: Maintenance & Repair

Hey internet.

I bought my Grand Am GT 2005 a 2 months ago. It
has been an excellent car up until about a week
ago when intermittently, the battery would be dead
when I went to start it (even if it was only shut off
an hour earlier). I took it to a repair shop and they
diagnosed it as a simple dead battery. So, I bought
a new battery that day and the next, I swopped it

Now up until taking the old battery out and putting
the new one in, everything worked perfectly. The
radio worked, I had no error codes or lights, it
started on one crack.

But after installing the new battery, my car won't
start. I have tried numerous different things so far
and non have seemed to help. When the key does
into the ignition, the dadh lights up for a quick
second and then all lights turn off except for
Service Engine Soon. There is not flashing security.
The radio only displays the time, won't turn on or
tune to any stations. When I turn the key to START
there is no sound. No crack, no fuel system,
nothing but relays clicking. What I have also tried is
jumping the starter, which when I touch the neg,
and pos with a prydriver, it turns over, ignites, runs
for 3 seconds, and then shuts off.

I am at a complete loss. Please, I could realllllyyyyy
use some insight!

Sounds like the ECM is acting up. No one looks at the car's computer first and you will never get error codes when the computer is failing. I had similar issues with my Olds and got tired of chasing ghosts, everyday would be a different problem. My OBD would not communicate with the computer so I swapped out the computer and haven't had any troubles since. I realize it's not cheap but you could spend that going to the garage every week, not to mention your time wasted.
