1995

Car turns over but won't start. I've replaced the crank position sensor, coil packs, new battery and the cylinder have good compression. I did notice lately I can turn the key and when it's in the on position I can pull it out. Any ideas why it won't start? Does a 1995 have a theft system...

I have a 1995 chevy tahoe, I am pretty savvy with cars and my truck is driving me nuts. It is running really rough and burning through fuel like crazy. I have replaced some components and i cant figure it out, heres what i have done. It was stalling out so I replaced the computer temp sensor...
