Ok, i replaced my old oem check valves with dale clarks viton check valves. so i started my car and it idled fine but i had a check engine light. so i went to pull the car out of my house and when i gave it gas it died. it did that a few more times now it wont start what so ever. it will turn over and die right away. i dont know if the fuel pump can easily be heard by putting your ear up to the panel but i didnt hear it running. The 20amp fuse for the fuel pump is fine. Any suggestions?
