Loses power going up hill and won't take fuel

Truck loses power and won't take gas when going up an incline - especially after a few miles. If I stop and shut off the engine then re-start, it is ok for a few miles, but then it happens again. If I don't stop and re-start then the truck will die and the battery will be drained.

If you're finding it difficult to service/repair your car, get one of those online manuals. You'll not have to wait for others to answer, or rely on
mechanics and all. Plus I know a website that has very good manuals online, without expiry i.e. for lifetime.

SOURCE: Truck losing power and service engine soon light on

Like to other guy said, give it a tuneup. Also try SEAFOAM to clean carb up of slug. Also check to make sure the butter fly for the choke has not come loose, causing it the choke it down. Failed choke pull-off.

SOURCE: Losing power/acceleration on hills

Change or clean the EGR valve and install a new catalytic converter.
This should take care of the problem.

Sounds like your fuel filter need's to be changed. Start with that and good luck.

SOURCE: 98 gmc jimmy loses power to a stop

the fuel pump could actually be malfunctioning. and the reason that you are able to restart and drive again is because when you turn the key on it is allowing the fuel pump to pressureize your system. but while the fuel pump is continuasly running it is loosing the fuel pressure. this is common on the cheap fuel pumps. i am not sure about were you got the fuel pump from but in all of my experiances with this problem i find that the fuel pumps have been boughten at a napa store.
i hope this helps you out.
and you could attach a fuel pressure gauge on to the fuel rail and start the car and watch the pressure to see if it is droping.

When taking off, the truck loses its gas pedal and will not go any faster than about 5 miles and hour. How do you fix this?

I would change out the fuel filter first because it's the cheapest and usually the problem

Losing power in accelation

Fuel filter is probably clogging up (it's common), which restricts fuel flow and makes it hard to make the needed power for acceleration or other high-load situations like climbing hills. Change it and you'll probably be fine.

1984 Rabit loses power while going up an incline

you need to check the accumulator and make sure you are getting the correct fuel line psi. Also if it sat a long time with old gas in it it could just be old gas accumulation and deposits. get a good fuel line and injector cleaner one that dosn't say STP and cost's more than $15. One that has to be done threw the fuel line or injector ram. You can try using seafoam, its seams to work pretty good in this type of situation just look it up on UTube.

good luck

1984 Rabit loses power while going up an incline

Fuel pump and injectors are plugged. Any time a car sets with gas in it the gas separates and will varnish the fuel pump and injectors and possibly cause a fire just like a Vette I had to work on had the same problem. That means new fuel pump and filter and possibly injectors.
