I had similar issues with my 1987 Mustang GT. I wasn't getting anywhere during my troubleshooting like I said the same issue you were having .....with the fuel pump priming but no start. I researched further and spoke with a older coworker Ford Fleet tech, he told me that a common problem was the TFI module attached to the Dizzy. I replaces with with a Wells generic module.... still no start....2 more months of painstaking troubleshooting. I started backtracking and thought I would spend $50.00 and replace the TFI module with a Ford Motorsport oem tfi module turned the key.... and she started without hesitation. Long story short don't throw your hard earned cash at parts that will not fix the issue at hand. Read up and Research when you fix the issue you will know that stang better than the engineers who developed it. Hope this helps someone fixing or researching there late model Ford Mustang. Ryan MN

Replace the fuel pump relay underneath the drivers seat. Sometimes you can can tap on the old one and get it to work.

1988 ford mustang inertia switch locaton


More than not its the ign module in the distributer.. this is the way they fail.. 2. the fuel pump on these cars are a problem too.The fuel pump is in the fuel tank. go to the rear of the car in a quiet area have someone just turn the key to on, not trying to start the engine. if the fuel pump runs it will run for about 1.5 seconds and you should be able to hear it .. it will be a buzzing noise. the relay just turns the pump on for a short time to charge the system then when the engine starts the relay via the computer turns the fuel pump on to supply the injectors. The reset is a cable is in the trunk of the car on the rear right side. it has a plastic tag on it for identification. The problem could be a clogged fuel filter.. mounted just in front of the tank under the car. If the IGN module is out there will be no spark.. check that before you start removing the tank.. I just bought a pump, a filter and an ign module for that car from www.Rockauto.com.. best prices anywhere. Pump was 1/4 of what autozone wanted for it !!

have you changed the fuel filter yet? They do clog up. That or you may have trash in your tank, and the screen is clogged. Hopefully its the fuel filter. The pump screen is located in the tank, and that means dropping the tank. hope this helps

Engine will not start.fuel pump does not run. intermittent problem. has been getting progressively worse. have changed fuel filter. checked electrical connectors.need accurate wiring diagram. chiltons...


start by checking the fuel pump fuse and relay. will the fuel pump run for a few seconds when you turn the key to the run position? If so you may need to replace the crank position sensor. When this goes bad the engine will turn over and start, but only run for a second or two then die like its out of gas.

If you do not hear the fuel pump coming on and the fuse and relay check out good then you will have to see if there is power going to the fuel pump. if power is present at the fuel pump plug then the fuel pump is bad

1988 mustang 5.0 efi flooding engine will not start fuel pump constantly running, fuel reg. replaced will actually fill and with fuel and only fire if pedal is to the floor?


Step one
Click the key forward BUT don't start the car listen for fuel pump to pressurize and shut off. But if the pump keeps running change the fuel pump relay switch under drivers seat. If its pressurizing and shuts off then its not your fuel pump. Fuel pressure at rail when idling is 30 psi.
Let me know what happens cause I know alot about Stangs had 2 5.0
