My husband hit a deer and it was on the passenger side the headlight came out and so did the blinker. The passenger fender was cracked. My husband replaced it and and my son drove it and the check engine light came one and the oil pressure light came one and it just shut down. It acts like it's not getting any gas is not completley turning over to start. My husband thinks the oil pump or oil sensor or both could have gone out. Do you think this might be the problem? What are other things he can look for as a troubleshoot problem?
