I have a 2008 8 cobalt with the 2.2 ecotech. As of right now it won't crank over. I get power to all crank relays except one, no power to fuel pump relay or fuse and no power to the pcm fuse. It you can help me out would be much appreciated.

I've checked every fuse, gound and power source. I pulled the fuse box and inspected it for a fried connection. I have power to all the fuses except the ones mentioned above.

Hi
I hope I can help,
did you check the relays under the hood for the fuel ,crank and pcm,
I had problems like yours ,and it was ether the fuses or relay ,or you can even
look at the bcm fuses under the hood left corner there s a 3o amp and a 4o amp,
that could be the problem too .

hope it helps .
