I have diagnosed that my problem with not cranking is related to the fuel pump. I check my coil and I am getting a spark. I can crank and run for a few seconds spraying carb cleaner in the intake. Doesn't this series of truck have 3 fuel pumps, one in each tank and one up on the rail?

 

"Cranking" is the starter spinning the engine, and it sounds like yours cranks fine.
"Starting" is the change from not running to running, and it sounds like yours is doing that, too, when you spray fuel in it.
"Running" is what your truck has trouble with, and the carb cleaner says it's related to fuel delivery.

'90-up trucks only use a pump in each tank. Only '84-89 EFIs have a frame pump.

But it doesn't have to be a bad pump - it could be a bad relay, an open or bad inertia switch, a blocked fuel filter, a kinked fuel line, or bad gas in the tanks. How many tanks does your truck have? How long has this symptom existed? Does it affect both tanks? Have you checked fuel pressure with a gauge? Can you hear any fuel pump run if you cycle the key to RUN? Click my black Bronco in my signature & read the captions in the '90-96 Fuel System album.

 

To Preface:

I only drive the truck a few times a month, because I now have a company vehicle. My needed to drive it a couple days ago because her car was being worked on. She put new gas in it and it ran fine for a day and then it would not crank or run.

It has 2 Tanks and it will not crank on either one. It has done this for 3 days. I have not check the pressure because it is a devil to get the filter off (On my truck it is wedged between the front fuel tank and the skid plate). I can hear the pumps whine for a second or two when I turn the key to run.

 

If you hear the pumps whine then the pumps are MOST LIKELY okay. To check the fuel pressure you hook the gauge up to the shrader valve on the fuel rail, which is on the engine, on the driver side, next to the valve cover on the front.

 

You keep saying "crank"; do you mean the starter doesn't spin the engine?

 

Sorry I mean start

 

booba should I get a reading on the shrader valve around 35 psi? Should I check this while to truck is sitting or while it is running off the carb cleaner in to the intake?
