Question about 1989 Ford Ranger

1 Answer

Fuel pump? I have a 1989 2.3 liter 4x4 ford ranger. It idles good but when its being driven, sometimes the engine will bog-down , start doing a real fast knocking noise, and not go over 20mph (one time it done it to me when I was driving 70mph on the highway). It seemed the harder you pressed on the gas pedal the more it will bog-down when started to act up. But sometimes it will be running great and the engine will run strong. I poured 2 bottles of "HEAT"( it gets rid of any water ) in the fuel tank and it dint help at all. Ive took it to 2 mechanics and the first one checked the fuel lines, fuel filters, and I think he said he checked the modulators but he could not find the problem. And the second mechanic has driven it for 2 days and it has not acted up on him. Im 90% sure its the fuel pump, because 3 months ago it got replaced and it was acting very similar the way its acting now (or so they say it was the fuel pump?)

    Well I feel like a fool but so should my mechanics. I found the problem by simply checking the oil, it was 2 quarts low and the oil was burned up!!! The night i found it was low I changed the oil (gtx 10w30) and filter. Now it runs ALOT better but the engine acts alittle funny.

    I agree completely. No it could not have been the fuel pump either of the times but i got charged for it the first time they screwed me and it was never put in anyways.

    Good call and well your a big person to admit it. The fact is that you rely on a professional and like my friend said you get about 70% from the average mechanic. They just do not care and they also do not realize that this is your life and you need to rely on their quality diagnosis.
    Ok I am off my soapbox.e

    It is not a fuel pump problem, if it was it would act up all the time.

Well this could be in your timing. As cars get some miles on them the timing chain stretches therefore causing you car to lose alot of power.So you may want to have your timing set on this car. Also I had a taurus that had a bad torque converter, and it lost alot of power on hills and under loads, also when i gunned the gas pedal. so try the timing first. Hopefully you dont have a bad head gasket or a cracked head these symptoms you are describing are all signs of head gaskets or blown heads

SOURCE: wont start

CHECK SHRADER VALVE ON FUEL RAIL FOR PRESSURE. IT IS COMMON FOR PUMP'S TO GO OUT. YOU CAN HAVE SOMEONE LISTEN TO TANK FOR A BUZZ NOISE ON KEY CYCLES OR TEST FUEL PUMP CONNECTOR HARNESS FOR POWER. TRY KEEPING AT LEAST QUARTER TANK AT ALL TIMES TO KEEP FUEL PUMP COOL,SOME PEOPLE DRIVE ON LOW AQLL TIMES AND KEEPS PUMP HOT CAUSING PREMATURE FAILURE.

2.9 Ford engine. Loss of fuel pressure and throttle response. Starts hard when cold but okay when warm as it has fuel pressure. Fuel Pressure regulator? You feel lack of throttle response when...


Its possible that its the pressure regulator. But its more likely that its the fuel pump or even the fuel filter You say it olny starts to run bad when you give it more gas. If it were the pressure regulator then it wouldn't matter becaues what that dose is keep the fuel pressure constant under all driveing conditions. Although the problem could be to much fuel witch could mean the regulator is allowing to much fuel to enter the system. Pull some plugs out and see what they look like they should be a tan color if the engine is running good if there gas fooled wet and black then its is to much fuel if there kind of white then its running to lean and its not enough fuel and you should check the delivery system pump and all filters well good luck

92 Ford F150 4.9L. starts good, idles rough, dies at slow speeds


4.9 litre ?? you having a laugh its a 10ton truck engine not a pick up -global warming machine,remove the pump/sender unit and check the gauze filter also look inside tank for a something floating around ,i think the idles is not a related problem to the vehicle losing power but their is a possibility you could have a problem with the little vac operated thing on the fuel injector line that allows the fuel through only when the engine is running

1989 Ford Ranger 2.9 liter 4x4 Runs Horrible


change fuel filter. add can of SEAFOAM(parts house) to fuel. It sounds like the beginning of EGS(ethanol gas syndrome). corn liquor substance, water, and clogging. all caused by ethanol fuel.

1989 ford f150 w/ 5.0 liter..... engine light on


I would check the oil pressure of the engine. The reason is the timing chain tensioners are run with oil pressrue. I think your timing chain tensioners are leaking down when engine is getting to operating tempature . The oil is thinning down as warms up , as it should to lubercate . I would check compression and do a cylinder leak down test on all the cylinders. Then if the compression is good and the cylinder leak down is good. I would change all the timing components, ( chain, timing gears, timing chain tensioners )

Good Luck , I hope this helps.
