Please tell me the extent of the damage, did the car run after the incident? Have you tried checking the fuel pressure? If the fuel pump is bad, try spraying some brake clean or other type of flammable spray into the intake to see if it will let it run for a moment. Keep in touch à â Â

Well the car was in a front end crash. I had to replace both fenders and the hood as well. I did spray some choke cleaner in the intake and the engine run for a few moment. I also checked the fuel pump fuse n it's ok
i check the power connector at the top of the fuel tank that supply's current to the fuel pump but did not get any power out of that. I was thinking there's a safty buttom or a relay somewhere that need to be reset, maybe because of the accident. What do u think?

The possibility is that the fuel pump or main relays are in need of replacement.
