1995 Ford Explorer Wont Start

The problem is that the fuel pump continues to run while the key is on. It turns off if the key is off.

I swapped it with an identical relay but it does the same thing. Other forums keep mentioning a green fuel pump relay but I dont see it anywhere.

Inertia switch is not tripped. How would I go about checking the pcm?

I switched the fuel pump relay to the pcm power relay as they are the same part number to no benefit. Despite my best efforts, I foresee this one ending up at the shop.

I take the #19 fuse out and turn on the key and the fuel pump does not come on. Replace it, and the fuel pump comes on like normal. Just doesnt shut off.

I have zero clue what you mean. Sorry

You said your truck fuel pump runs all the time with the key on. Is it a truck or a ford explorer. Two different things. Ford explorer fuel pump relay is grounded by the PCM. Maybe you need to check to see if you also have spark at the spark plugs. If not you need a test light or noid to check the injector circuit to see if it operation. With a test light test check one of the injector plugs for a completed circuit.
Take the test light put one end in one side of the plug and the other in the other side. Have someone turn the engine for you and see if the light flashes If no spark and no circuit at injectors and pump running all the time. I would expect your PCM is Bad.

It should be getting fire from the plugs because it's starts when the carb cleaner is sprayed into the intake. Also the vehicle (explorer) started (just like normal)twice today and ran for about 30 seconds and shut back off.

Ok it runs sometimes, but the pump is running all the time.
If the pump is running and it has fuel pressure (hope you checked that when it doesn't start) The pcm is probably needs replaced because the fuel pump relay is still grounded by the pcm. Now if you would check that circuit at the injectors when it will not start to see if the light flashes you will know for sure. A test light is a cheap item at any parts store. I am not reading this from a book. I do it every day and for the last 40 years. Hope this helps.

What is the little grey box on the right hand side of the intake that has a 3 prong plug on it? Several times, I have moved those wires and the fuel pump shuts off. Then it turns back of again as if it vibrates back into a spot of bad connection.

I really think you mean the left side. The drivers side is the left side. Little grey box is the DPFe sensor is the only little grey box on the drivers side of the intake and even if you unplug the thing the auto will still start. Far as I know it has nothing to do with the fuel pump. The idle air controll and tps is also located on the intake at the front.

It may be purely coincidental but, when I move those wires around, the relay clicks off and the engine runs like its brand new. I dont get it.

It seems you have a loose connection there some where. Try cleaning the plug and closing the pins on the plug a little.
