PPS: I had a Cadillac which would work properly if the drivers door was open. It turned out that the ground lead from engine to chassis had been ruptured. I repaired that and added another ground from engine to frame. With the broken connection the system had been using the drive shaft to rear differential for ground and the bushing on the transmission tail piece had been “eaten away” and I had to replace the bushing and seal. Why did it work with the drivers door open? I THINK it was using the lighting circuit for a ground.

I replaced the alternator and battery on the explorer and now when pressing down the gas pedal the car will not accelerate or rev the engine. Any ideas?

The most probable cause is that you disturbed the TPS (Throttle Position Sensor) connection. The TPS controls the computers response to accelerator position and therefore controls the "revving" of the engine. In you vehicle the TPS is part of the (ETC) Torque-based Electronic Throttle Control system.
IF you have the Accelerator position sensor located inside the cab at the top of your accelerator, you have a ""drive by wire system" and you will need a good mechanic with the proper test equipment to diagnose the source of your problem. BUT you could check the wiring going to the throttle body. My bet is that you disturbed a wiring connection. You should be getting an engine warning light coming on on your dash. You can read out the codes the hard way if you have a haynes or similar manual, but a good readout instrument such as the Actron makes the checkup much easier. A few mechanics will charge you $35.00 to give you the answer with their test instrument.
 
On a different aspect of your repair: I am very tight when it comes to replacing components such as batteries and Alternators and do not do so until I have bench tested those components. Nearly any parts supplier has the test equipment to check the condition of these components and will do so if you bring the alt. or battery or both into them. Some can and will test them on your vehicle for free or a very nominal price.
 
Don't waste your money unnecessarily replacing components, and DO use only trustworthy mechanics. In today's market, FAR too many are parts swappers who will break your bank. A dealership with an outstanding reputation is very jealous of that rating and they are actually cheapest in many cases ESPECIALLY when it comes to control systems, which are HIGH profit items. Integrity is becoming a rare commodity unfortunately.
