Question about 2000 Ford F350 Super Duty Super Cab

2000 F350 Super Duty V10 Power problem

At an idle the truck seems to run fine,Put it on the road and it spits and sputters when you try to accelerate, I did the obvious things, fuel filter, air cleaner. I am thinking that it may be the fuel pump? I have ha dnumerous problems in the past with General Motors fuel pumps and the last one that i did had the same symptons and the solution was the pump. I have checked the pressures and I need to now first of all if I checked at the right spot.....On the injector fuel rail on the right side of the engine near the rear, and the pressures that i got are key on engine off 13psi, engine running 30 psi, shutoff engine and the pressure dropped to 28psi and after a few seconds came back up to 32psi with engine off. Could you offersome help?

Check the fuel pressure while the problem occures....needs to hold 35psi or so under load. You might also have ignition breakdown. Is the Check eng light on? You have coil on plug right? you really need a scanner to id the misfiring cylinder the try moving coils around to see if the problem move with it.

I have a 96 ford explorer, will start and idle fine , sometimes it will accelerate fine then I will loose RPM/speed and have to pull off road sputter out til it dies. press gas to raise rpm nothing


Try the fuel filter. If that is not a problem then the other thing I would suggest is to check the fuel pump. If the pressure is being lost in the fuel pump then your car will lose it's acceleration.

Acceleration and/or fuel problem ??


Check your Fuel Pressure. You may have a bad pump or the intake sock is plugged.

Engine missing out, spitting and sputtering


the problem you describe indicates a air/fuel ratio problem so I would be looking at any hoses that may have perished, MAP/MAF sensors and coil problems. If it is possible then get a fault code reading as it will save money from "guess" repairing

Old '87 ranger been sitting in folks yard few years. fires up fine, but spits and sputters going down the road


Old fuel in tank, fuel filter clogged, plugged/clogged carb. or fuel injectors.

1. Drain fuel from tank and replace with new fuel with SeaFoam or Lucas

2. Repace fuel filter

3. With engine running at a high idle and air cleaner off, spray or pour carb/fuel injection cleaner into carb/fuel injectors.

If problems persist, check plug wires for cracks and/or breaks. Pull spark plugs checking for fouling.

Somewhere along the the line you may have a fuel blockage or a good dose of water in your fuel tank.Check the water in tank 1st.Add 1 litre of metholated spirits to every 20 litres of fuel.This will allow the water to break down and be burnt through the motor over time.Do this twice.If this does not work,there may be a glob of **** in the fuel tank that blocks the pickup.If this is the problem,the tank needs to be taken out and cleaned.I hope this is a start to get you back on the road.

1995 Jeep grand cherokee is missing while running. When it is under a heavy load (driving fast) it runs fine. When idleing and slow driving it spits and sputters.


I have the same problem on my 95 grand cherokee laredo. Sometimes it starts out fine and after about 10 miles it starts spitting and sputtering. Then after a while it seems to clean out and run fine again for a little while. Then other times it starts out spitting and sputtering at the begining. I changed the fuel filter and that was not it. It is a 4.0L 6cyc. Any Ideas?

Thanks,

Internal combustion engines requires 3 things... fuel, air, and spark. You do not have enough of one or more of these. If the wires and plugs are old, change them.  Air filter, same thing.  Fuel filter can also clog up with stuff after awhile. When you take a look at the air filter check where the air comes from.  It is possible a little critter has built a home and blocked the air flow (rare, but, it has happened).
