I just got a 93 ranger with the 4 cylinder. It had been setting a couple years with some gas left in the tank I got the tank pretty well empty and put about 3 gallons of high octane in it. After cranking and cranking we could only get it to fire on either sprayed into the intake. I know that the gas getting old is not good and I understand it can gum up the fuel pumps? I already pulled the bed off so if I need to pull the pump what is the procedure? And also for getting this thing started what else should I be concerned about I am sure it is not geting fuel to the cylinders. I am sure pulling the fuel pump is simple I am just not used to working on things like this about all I have worked on are 50 year old trucks and tractors LOL

Well for starters, no high octane. That is not better for the engine, in fact it is harder to ignite. Those numbers are a resistance to ignition.

Turn the key on and look for the test port on the fuel rail under the hood. It will look like a tire valve. Pull the cap and push it, see if any fuel comes out. If so, pump is good and working.

Pump comes out the top of the tank. Remove the lines and electrical connector, then use a screw driver and hammer to CAREFULLY pound the lock ring counter clockwise. Then the pump should lift right out.
 
Okay thanks for the info I was wondering if that was a locking ring. I will check out the port with key on and go from there.
 
You should change the fuel filter and flush the lines before replacing the pump.

Thanks for the reminder I replaced the filter and pump today and have it running they said it was burning oil so and it does indeed smoke we discovered.
