Evening All.

Was stuck in traffic today on the interstate.

2008, lt, 99K. Engine died.

Has all electrical power, cranks, does not start.

Checked all the fuses, and they are in place. Disconnected the battery for about an hour, reconnect and still cranks but no start.

Saw there are plenty of threads, but cannot seem to find any solutions.

Thoughts from the gallery?

Thanks!

my best guess if a fuel pump. if it still cranks, battery/alternator/starter are working. if the engine didnt make some noise(breaking parts), its should still be able to have compression. really only leaves fuel and ignition. im not 100% sure how the ignition works, but its all electronic. meaning no distributor or rotor. so thats how i arrived at my theory. good luck with your hhr

 

Carl-

When you turn the key ON, do you hear the electric fuel pump running in right rear (gas tank area) ?

 

I remember the good ole days. Shooting a little starter fluid down the carb to see if a dead engine would fire off. If it did,then you knew you had a fuel problem. I miss the simple days.

 

i suppose that could still work? open the airbox and spray a little in the tube? probably set off the MAF sensor

 

You will lose your eyebrows that way.

 

And to a ton of potential damage too.

 

Went out and turned the key.

No fuel pump sounds.

So, calling mechanic on Monday!

Will post the final solution when I get it, thanks all!

Check the fuel pump fuse and relay. Not sure on these #s.Fuse 13.Relay 19. Try replacing the fuse even if it doesn't look bad. The relay can be swapped with a known good one just to check for voltage to the pump.

 

Hope that its a fuse or relay, replacing that pump is neither easy nor inexpensive.
