Hello, I'm Cam.

Ok William, what is the history on this? Has it been getting hard to start over time? Lacking power? When you turn the key on, do you hear a small electric motor in the fuel tank turn on for 2 seconds? If no, can you get someone to kick or hit the bottom of the fuel tank HARD while trying to crank it.

Expert:  GM Tech (Cam) replied 2 years ago.

OK, lets take a couple minutes and check the fuses again. One may have been put in the wrong place, may have popped, something like that. Was there any corrosion, mouse or rodent tracks on top of the fuse block?

Customer: replied 2 years ago.
checked every thing twice already
Expert:  GM Tech (Cam) replied 2 years ago.

OK, so the small motor sound in the tank, is that there?

IF so, can you check for spark at any of the spark plugs?
