          I found when I changed this part on my 1991 F150 my battery quit going dead overnight.
          to test mine, I unkooked the hot wire going to the starter relay and heard things "clicking" off...
          Over on the driver side is where this resides, usually under a plastic cover... when I unhooked it, it made the same sounds as unhooking the starter relay.

              Happy to help you Wolf! It is possible that the relay could be the cause. This part does show to be an exact fit for your car. I suggest having a certified mechanic have a look for a full diagnosis.

              Hi Cowboystuff, to get more specific information on the location of the ECM wiring relay I would recommend purchasing a Chilton or Haynes Repair Manual for your 1984 Ford E150 5.8 engine, not only will it show the location and also explain how to install, but you'll find it handy for many more projects on your vehicle.

              I'm happy to help, Poet! In the 1992 Ford Tempo GL 2.3L the relay is located within the integrated relay control module. It's approximately 6"x4"x2" and a large rectangular connector with multiple wires connected to it. It will be on a bracket mounted on the driver's side strut tower.

              A:

              Hi John, my answer to your question on the BWD Engine Control Module Wiring Relay - part# R648P is that the relay may be the possible cause of the problem on your 1988 Ford Bronco. However, without the presence of the vehicle we could neither diagnose the problem nor provide you with a 100% answer. I would suggest taking your vehicle to a certified mechanic for a proper diagnosis before buying and having parts installed that may not solve or be the problem.

          • Q:

            I have a 1987 mercury colony park station wagon with a 5.o engine. while driving to work the car will shut off while driving. most times it would start right back up, but a few times I had to use starter fluid to get it running again, the problem became more and more frequent. I replaced the fuel pump as recommended by more then one mechanic. once the new pump was installed the car started right up , after about 15 minutes of running it shut off, but started right back up. as I was driving home the car kept shutting off if I had to stop for a traffic light or stop sign. the only way it wouldn't shut off was if I kept my foot on the gas peddle and brake peddle if I had to slow down or stop. anyone have any idea what would be causing this problem. I would really hate to junk this car because it has been so reliable to me for the last 12 years with no problems other then a water pump . I have been told it could either be the egr valve or the fuel pressure regulator or the fuel pump relay

              With reference to your inquiry on the BWD Relay - part# R648P, the problem on your Mercury Colony Park - Station Wagon may be with the EGR valve and or even with the fuel pressure regulator. However, I would suggest taking your vehicle to a certified mechanic for a proper diagnosis before buying and having parts installed that may not (solve/be) the problem. For any further assistance, you may also visit your nearest Advance Auto store or call us directly at 1-877-ADVANCE (238-2623) and one of our representatives there would be more than happy to assist you.

            I have an '89 mustang 5.0. The fuel pump is not comming on when i turn the key to the on possition. I already confirmed that the fuel pump relay is working and have a jumper in place of the fuel inertia switch to be sure that is not the problem. Can a bad eec power relay cause this problem??

              Unfortunately we are unable to diagnose what is wrong with your vehicle without being able to be there with your vehicle. However, I would suggest taking your vehicle to a certified mechanic for a proper diagnosis before buying and having parts installed that may not (solve/be) the problem.

              did you check the fuel pump to see if it still works? also check fuses and the wiring to the fuel pump? its kinda hard to say. but when mine did that it was my fuel pump relay. but my pump was brand new. it could be the eec but i havnt herd of those going bad alot.

              It might be the problem in the igniter which provides spark through the ignition coil. It is located in the distributor.
