LOCATION OF THE FUEL PUMP ON A 1983 MUSTANG V6

sounds like the immobilizer is locking out the fuel pump,
have you replaced the key without reprogramming it?if so take the old key and the new tape them together at the tops cut portions facing in opposite directions and try starting the car that way the security light should go out

The fuel pump relay is inside the CCRM and CCRM is located right next to the coolant overflow bottle, its a small black box. Rockauto has an image.

V6 and V8 take the same fuel pump.

First thing to note is that the relay is housed in a Constant Control Relay Module (CCRM). This module contains the relay for the Fuel Pump, Cooling Fan, and Air Conditioning Clutch.

In our 1998 Mustang V6, the location of the CCRM is behind the passenger side wheel well plastic cover. Looking at the wheel dead on - it's found at around the 1 o'clock position. To confirm it's location without removing any plastic wheel well cover - pop the hood, and look for a wire harness routing from the engine compartment INTO the passenger side front fender (near the air cleaner). Flash a light in there, and you'll see a connector attached to the module.

I'll save you some headaches in finding the right size tool to remove the connector as well - I used a 5mm nut wrench to remove the connector from the module. Do this first so that you can access one of the two bolts that holds the module bracket to the fender. found this at the allfordmustangs web site. hope this helps

If the Pump relay under the hood is still good, the fuse under the hood and inside the vehicle are not blown then the pump is faulty, replace the pump. If you need clarification on where any of these fuses or relays, the location changes almost every year, are I recommend that you get the Haynes repair manual on your vehicle.

looking for the fuel pump relay switch

It has a carb right. It is screwed into the carb. The fuel line is screwed to the filter.

The electric fuel pump is inside the fuel tank
check it and rate it

that trnas will not bolt up and since you don't have a computor control the trans wount interface with the harness it requires which you do not have on your vehicle. please rate this solution
