Fuel Problem
Hello,
Seems I have a fuel problem. The victim is a 1989 Ford Ranger Std., Cab 2wd w/o AC, and a 5 spd. It is my sons truck and it was given to him by his Uncle for his grades (a's in HS). The truck has been sitting for about a year and we brought it up to Oregon from Acton CA. So far we have changed the fuel filter and we know that the fuel pump is working as we get a good stream through the fliter and to the the fuel rail. My next thought was the TPS but I was not sure. My son bought a Haynes manual but it is very vague on this subject. Any thoughts?
Thanks

welcome to FTE!
what symptoms does the truck have? did you replace the old gas with fresh gas? do you hear the fuel pump kick on for a few seconds when you turn the key to the on position?
for starters, I would put a fuel pressure tester on the fuel rail to check the pressure. there is a sticky at the top of this forum entitled Technical Information. in that sticky there is a link for testing the fuel pressure. Also try pulling the codes, there is a link in the tech info sticky for that also entitled Pulling EEC-IV codes. check them out.
if you need anymore help let us know. good luck.

Fuel Problem
Thanks for the reply.
My son and his uncle placed about 8 gallons of new fuel in the tank as it only had less than an 1/8 in the tank. They also place a fuel stablizer and an injectore cleaner in the tank with it 8 gallons of fresh fuel. The truck will run under a shot of starting fluid. It will not start under with it's own fuel supply. My brother in-law decided the other day that he was going to tinker with it (he has been told not too) and said that there is a bleed valve by or on the fuel rail that needs to have the air bleed from it. He said he accomplished that but it still will not run. The engine cranks but it has no fuel to start. The fuel pump seems to function. When you turn the key you hear the fuel pump kick into action and when I was under the truck I noticed/felt the slight vibration of the pump as well as heard it actually working. What tool would I need for the fuel pressure test and for pulling the codes? My thought was that the TPS was bad (codes should show that) or that the injectors might be plugged (sitting for a year).
Thanks

Since it runs on the starting fluid AND you hear the fuel pump run for 2 seconds, it might be that the injectors are not firing.
Is this a 4 or 6 cylinder?
Step 1 is to pull the trouble codes.
EEC-4 code scanners are dirt cheap, my Actron CP-9015 was 30 bucks at Pep Boys.
Or-as mentioned-see the "Read first tech info sticky"

Thanks,
I will buy a unit as described and go from there. The engine is a 4 banger. I also printed out all the suggested info in the previous post's and will be taking them home for further study. This is all just frustrating but, what can you expect for a FREE Truck (single owner commuter truck with a straight body, matching camper shell, no rust and clean interior). it just had a clutch, timing chain/belt and brakes done about 30k miles ago but it does need tires.

Yeah, it does sound like a nice truck and worth some aggravation.
BTW, you should be able to hear the injectors clicking when cranking with a piece of garden hose used like a stethoscope.
I think the injectors on the 4 cyl. are timed by the crank sensor (or is it a cam sensor) So when you hook up your scanner a crank or cam sensor code would be good.

Well, problem fixed! 
I did not have time left as I am booked on the road for the next month so I finally had to brake down and take it to a local repair shop. They found that the fuel pump was bad. Got it replaced as well as the sensors reset. I pulled in from the airport last night and my son rushed out to so me that his truck, new tires and all is ready for him to start driving it to school (September) but next I must teach him how to drive a stick. One last thing, now that it is running the Rear Anti Lock Light is staying lit. I will frst verify the obvioius like fluids and MC float before I dive into it further. I do know the the brakes all around are almost new and there are no leaks in the Blines.
Thanks for the help!

Thanks Ken.
It is hard for me get to pull the code. I live in a town of 21k and no one in town rents or loans a code analyzer. I will probably have to take it back to the shop if the basics are in good shape. I have also read a lot of threads on this sight and will be checking the sensor in the rear of the truck.
