1988 F-150 loses power while accelerating

I have a 1988 F-150 and I started losing power when accelerating. We narrowed it down to the fuel filter or the fuel pump. We changed the filter and got brown, dirty gas out of the filter. Is this an indicator of water in the tank? The tank has no leaks.

Experienced mechanics share their insights in answering this question :

This is an indicator that something is wrong with the gas tank. My advice is to pull the gas tank off and have it steam cleaned. There are places that do that kind of work. When they get dirty like that the filters only work to a certain extent. Particles like rust and other buildup will not be cleaned out by the filter very well. I’ve had a customer with that car and it had rust in the tank. The filter couldn’t clean out the small rust particles. The rust that passes through can clog up the fuel injectors and ruin everything.

I’d advise you to have the gas tank taken off and steam cleaned. Also, change the filter to see how it goes from there. If you do have it steam cleaned and removed, the guys look inside of it and see how bad the rust damage is inside. If it’s bad then you are better off getting another tank than trying to clean it because the rust will continue to come back. This is probably the problem with you particular car because it’s old enough and is equipped with a steel tank. New cars have gas tanks made out of plastic, which of course doesn’t rust. I’d recommend having a certified technician diagnose your acceleration issue accurately and fix your problem.

A sluggish Ford F150 acceleration may be the result of a slow electrical throttle response or faulty transmission, such as a bad gear, and a throttle controller upgrade might be needed. The engine temperature sensor, low engine oil, and a faulty gear ratio in the Ford F150 can all cause sluggish acceleration.

There is three.. don`t listen to that other guy.. my 88 regular cab had one in each tank and an inline pump near the diverter valve underneath the drivers side door in the frame rail. 10 people think this is helpful.

Common reasons for this to happen: Clogged Fuel Filter: Over time and through normal use, your fuel filter will become dirty and clogged. When this happens, the flow of gasoline to your engine diminishes, which can cause hesitation and bucking.

Intermittent sputtering on acceleration can indicate fuel, ignition, or emission system issues. Of important note, the engine in your vehicle is known for a cracked EGR tube, which causes a leak between the exhaust system and the intake manifold. This would typically cause the check engine light to illuminate.

The most likely issue is that a component is clogged. A clogged fuel filter is the most common reason, although a loss of power in your car could also indicate problems with the fuel pump or fuel line. Impurities or debris may be blocking the system, which causes the loss of power in a car.

There are two key ways to improve throttle response delay in your ford f 150: installing a new aftermarket throttle response controller or doing adaptive tuning and calibration. Both methods can reduce gas pedal lag. Some people use both. Most people don`t expect this upgrade to work so well.

The 1988 Ford F150 fuel pump relay location is in the fusebox underneath the hood of the vehicle. Simply pop the hood, look for a black plastic box in the rear-right of the engine compartment, and you`ve found the fuse box. From there, pop the tabs on the fusebox and flip the lid over.

Wheel Balance

When your car vibrates every time you drive at 50-70 mph, it is most likely that your wheels are out of balance. The vibrations will emanate from the steering wheel across the seat and through the vehicle`s floor.

The most common reasons a Ford F-150 engine makes a ticking noise are low oil level or pressure, an issue with the ignition system, or an exhaust leak.

Bad or Dirty Spark Plugs: Spark plugs are responsible for igniting the fuel in the combustion chamber. If they are not working correctly or are dirty they don`t ignite the fuel cleanly and the car can misfire or sputter. The plugs will need to be replaced or cleaned.

One of the most common causes of jerky acceleration is a dirty fuel injector. Your fuel injectors are responsible for pushing fuel into your engine`s cylinders. This means they control the timing and amount of fuel used to keep your engine running.

You will feel a loss in power while accelerating and at times intermittent jerks. To solve this issue find the fuel filter located in the engine bay or near the fuel tank in your car`s trunk. If the fuel filter is clogged replace it if you have the skills to do so or get it changed at your local mechanic shop.

Clean air filters and fuel injectors will reduce the strain on your car. An engaged emergency brake causes the brake to drag slowing down your car. Disengage the brake to solve this issue. Sometimes acceleration problems are just because of low fuel or poor quality of fuel.

Culprits include a dirty fuel filter, clogged fuel tank strainer, clogged or failing fuel injectors, or a defective fuel pump. On most vehicles replacing the fuel filter is a DIY operation.

Fuel lines, dirty air filters, and throttle body issues can all cause a delayed throttle response. You can avoid this issues by installing a Throttle Response Controller. Engine response time will be improved, and you`ll enjoy driving your car more.

Your 5.0L should be reading 35-45 psi on the fuel-pressure gauge with the key on/engine off, 27-37 psi with the engine running, 40-45 psi with engine running and vacuum hose disconnected from the fuel-pressure regulator, while at the same time being able to pump out 5.6 oz of fuel in 10 sec.

The TBI can run a wide range of fuel pressures, from 0.5 to 6.0 psi, even be gravity fed. The TBI is not attitude sensitive as it has no float chamber and so consequently is fully aerobatic.

Fuel-injection mania swept the F-Series in 1988; as of this year, carburetors were discontinued for this line entirely. The 1988 Ford F-150 came off the line with fuel-injected 5.0 liter Windsor V-8 engines, 4.9 liter straight-six with fuel injection, and the whopping International Harvester 7.3 liter diesel V8.

The fuel pump relay on a 1988 Toyota Pickup is located either behind the glove box or on the driver`s side kick panel.

The fuel pump relay is usually controlled by the ignition or Powertrain Control Module, and when switched on, will provide current to the fuel pump so that it may function.

Faster Driving (45 mph+)

Tires can get unbalanced from wear or tear, or because of more severe issues. If you think this might be your problem a normal tire rotation and balance should solve the shaking problem. Another thing that can cause shaking above 45 mph is a brake caliper that is sticking to the wheel.

With 400 horsepower and a beefy 500 lb-ft of torque, the boosted V-6 is, as we`ve found in many other F-150s, smooth and strong, and the transmission does its thing pretty much unnoticed. Together, they shot our Tremor to 60 mph in an eye-opening 5.5 seconds, but the truck feels even quicker than that.

Low Power Steering Fluid

This is a pressurized hydraulic liquid that presses on the piston and makes the wheels in a modern vehicle far easier to turn. It`s part of the “power steering” system that is ubiquitous in the modern automobile.

The engine loses power after a longer drive

ANSWER : It is possible that your fuel pump would be getting weak.

Often times if the fuel level is run low many times, this can cause the fuel pump to overheat. If the fuel pump overheats, this can cause it to quick working. The fuel inside the tank is what keeps the fuel pump cool. If the fuel pump gets dried up and runs to cause an overheating issue, this issue can happen again even if the tank is full.

I would recommend having your fuel pump and loss of power issue checked out by a professional mechanic. It is important to have this issue resolved by a professional because it relates to the fuel system which is a high pressure flammable liquid.

The mechanic you choose would run a fuel pressure test on your vehicle which will test the performance of the fuel pump. Since your fuel filter is brand new, if the fuel pressure is low, the pump is likely to be bad.

Once the final results of the diagnostic test are received and the decision to replace the fuel pump has been made, be sure to use only fresh gas as old fuel can cause problems for the new fuel pump.

After shifting into gear, i can accelerate but then there is no power to accelerate.

ANSWER : Does it feel like the transmission is slipping? If you are leaning into the throttle and the engine speed is increasing, but it feels like the vehicle speed isn’t increasing as it should, it may be time for a new clutch. One the clutch is worn out, it can be difficult to drive the vehicle as there isn’t enough friction material left to keep the bind between the engine and transmission. Consider hiring an experienced technician like one from YourMechanic who can come out and take a closer inspection of the vehicles lack of power and offer a more personal diagnosis then estimate the proper repairs.

Sporadic loss of power when accelerating

ANSWER : Hello. This can be caused by a number of things. If the Check Engine Light is coming on then I would usually start by scanning the computer for codes. If there are codes then it may give me an idea of what is going on.

If not then I usually monitor the signals from the sensors to see if any are failing. If they are also fine then the catalytic converter needs to be checked for clogging and the fuel pressure must be checked as the pump may be failing causing low fuel pressure.

From what you are saying it sounds like the fuel pump may be going out. If you plan on having this looked at, consider the assistance from a certified mechanic who can come to your home or office to diagnose your loss of power.

Truck loses power and tries to stall

ANSWER : Hey there. This is a common sign of a faulty ignition coil. Ignition coils are coated with a varnish-like insulation that becomes brittle over time after being stretched then contracted repeated as the copper beneath them expands and contracts at a higher coefficient than the insulation.

The insulation develops micro fractures that open when heated and close when cooled. When open, they allow shorting of coil windings and decrease or eliminate the coil’s ability to function. This type of temperature cycling happens because every time you shut the engine off, the fan stops running, the coolant stops flowing and the temperature under the hood rises. Every time you start the engine again the coolant flows, the fans turn on, and the temperature drops. The areas in and around the tops of the combustion chambers, the exhaust manifolds, and the exhaust components are hundreds of degrees hotter than the outside temperature under the hood. When this heat dissipates and is absorbed under the hood, it is trapped causing this cycling effect.

Components that contain heat sensitive materials include parts like coils, injectors, igniters, and some sensors. Any of these may be potentially subject to this same kind of heat problem which can be very difficult to trace. I would recommend having an expert from YourMechanic come to your location to take a look at your truck to properly diagnose the loss of power.
