Car wont start got it to start ran for 10 seconds and shut off. I used the jumper wire to get code it gave me one blink then two blinks which is 12 the code for it says systems normal no issues darn car wont start.

One more thing when I do turn the key on to start it the cooling fan turns on right away. So I took the fuse out for the fan the car started and ran briefly then shut off. I couldn't get it to rev up to keep it running. Car hasn't started since. Any suggestions? I have worked on a lot of cars but darn this one has me pissed.

Hi,

This sounds like a fuel issue so we need to start with that.

Here is a guide that talks about hard starting and possible causes. Some of this won't apply to your car but just take what does.

Here is a guide that talks about getting fuel pressure which was discussed in the first guide. Let's start with this and see what we have for pressure and go from there.
