I changed out fuel pump and filter a month ago it was starting and running good. Now it does not want to start. Fuel pressure about 48 psi. Will start if I spray carb cleaner in intake.

Make sure the fuel pump is coming on. Remove the gas cap and put your ear by the filler hole. Have a helper turn the ignition to the run position but don't try and start it. You should hear the fuel pump come on for about 3 seconds. If you don't hear it, check the fuse and fuel pump relay. If they're good check the wiring at the fuel pump. If that's good, change the fuel pump again. You may have gotten a defective one. I work for NAPA and unfortunately it happens sometimes. HTH. -Jim


May help to clean the intake,and injector,s.
