NO I didn't do nothing to the engine. When I got it, it was complete. All I did was switch the intake and exhaust manifold, and the motor mount that's it. Also When I go to start the car my main relay is making a clicking nosie. From experience I have found out that was because of a ground not properley grounded. But it is grounded, right on the thermostat housing. Could my relay be bad? Someone told me that my problem is that my fuel pump turns on when I first turn the key but it is not turning backing on when I start it. What do you's think
