Stalls only in reverse
I have a problem that I hope someone can help me with. I have a 1992 Ford F-150 5.0 with Auto. trans. that stalls and cuts off when it is shifted into reverse. It does not do it everytime but it does it quite frequently. It sounds like it is detonating just before it cuts off. It doesn't do it in forward gear, only in reverse. I have replaced plugs, wires, dist. cap, rotor button. Transmission has been rebuilt about 2 years. This problem started about a year ago.

I know this sounds strange but check your tranny fluid. A long time ago I had papa Ford replace my tranny and after they did it stalled when I put it in reverse. As it turned out, they only filled it with about 1/2 of the suggested fluid.
Hope this helps.

My 150 stalled when I put the truck in reverse recently. This may sound off-the-wall but in my case the transmission lines that connect to the radiator for fluid cooling were leaking onto the serpentine belt, causing the belt to slip and the alternator to stop generating enough voltage to keep the truck running! Just a thought.

Try unplugging the rear axle speed sensor and see if it stops. The ABS light will come on, and the speedometer won't work with it unplugged, but this will be a temporary test. Drive it for a couple of days to try it. If it corrects the problem, you probably have a faulty PSOM, or Programmable Speedometer/Odometer Module. Sometimes when these go bad, they send an overspeed signal to the PCM, which immediately cuts off half of the fuel injectors, and creates a stall condition. It is usually worse when the truck is first started in the morning. It happens so fast it doesn't register on the speedometer. If you have a jumpy speedometer this is a telltale symptom as well. Rebuilt PSOM's with an improved program are available through dashusa.com
