right ok i see. i have noticed today that it hasnt hard started since tapping on it. but yeah it still has the jolt. any ideas how to fix this problem?Tape on the relays is likely from the factory. Tapping it may jar the contacts loose if they are stuck open. The relay comes into play during cranking only, so it has nothing to do with your "jolt".
I dont have a specific tool to check the fuel pressure. but from the FPR, I did replace it with a new one thinking that would fix it. It currently holds a vacuum. but I have seen faulty FPRs hold a vacuum. maybe I just purchased a lemon. today I am going replace the FPR from my fathers 96 Deville and see if that solves the problem.Hows the fuel pressure?
