Changed fuel pump and filter.

I have 5speed c1500, after I drive my truck for about an hour and a half and take my foot off the gas they both work until I put my foot back on the gas

After I drive it for about an hour and a half my speedometer will bounce almost up to the speed I'm traveling and my techometer will work when my foot is off the gas, when I put my foot on the gas the speedometer got right back to 0 and the techometer stops. Trying to fix this so I can get it inspected.. please help

motor seems to operate ok window goes down about 1/3 down and sounds like it is hitting something in door panel and stops

What do I check

and tapp on the accelerator for the truck to run. I just bought this truck and the owner didn't know how to fix the problem. The truck runs awesome. You just have to tap the accelerator and turn the key during the same time to start the truck

the cluster is acting wierd .. The tach is reading around 1300 -1400 rpms but the its actually only idling around 800 andthe speedometer is around 20 mph off. i was having some problems such as while driving the RPMs would drop to 0 and MPH would jump to 100 or drop to 0 thr trans would drop to 2nd gear and would have to drive it there. sometimes if you shut the truck off it would go back to normal .. I put new ignition starter switch and instrument cluster.. starter switch solved the trans problem but not the cluster problems any help on this would be great thanks

when running my truck leaks engine oil that runs down the passenger side of the clutch housing and finally onto the y pipe where are possible reasons for this?

gas in the carb it starts and runs fine until i kill it. Next time it may start ok or I may have to pour gas in the carb again. What could possiable be the problem?

So this problem arose after i made a 800 mile trip from arkansas to north carolina. The truck made the trip just fine but once i got here, it wouldnt start after spending the night. At first i thought the problem could be the battery so bam, new battery. Problem persists. I then checked my spark plugs and went ahead and purchased a rotor and new distributor cap which i installed today. YES the plugs are in line and no lines are crossed. I went ahead and double triple checked. Still the problem persists. I can smell fuel when i crank the key so i know the fuel pump is good. Also i replaced my alternator less than 2 years ago so that should be good as well. Starter is less than a year old, battery is 4 days old, distributor cap is not even 12 hours old. If you have any ideas or comments or suggestions I would be very pleased to hear them. This is my only source of transportation and gravely need to be mobile. Thank you. --Jax

The truck has been sitting. I did 2 flushes and changed coolant now the gauge doesn't seem to work at all. Sensor, or gauge itself? Wiring issue?

I got a load squeal/whistle noise in the engine area.I temporarily removed the fan belt the noise was still there,I replaced 2 pulleys for the fan belt any way 1 seemed to be bad , sprayed throttle body cleaner in the throttle body while engine is running . the truck runs and drives fine. When i first start the truck in morning do not notice the noise after the truck warms up the noise is loud and remains the res of the day.

sound changes pitch slightly when gas pedal is barely touched, then returns to high pitch. Sound stays same with increased rpms. just repaired fuel return line due to rust out. changed fuel filter at same time a week before this started. Cleaning the throttle body didn't have an effect on whistle noise. Butterfly looks normal. Guessing vacuum leak on a component. where do you start? Thank You

I changed the fluid and filter,and there wasn't any noticeable shavings in the pan...Do you know what the possible causes could be?Thanks!

Changed bank 2sensor 1 twice still get same code what else Cani check

4.3 liter stalled pulling out of driveway. Repeated attempts to restart no go. Ether, gas prime, no go. Gauge shows 1/4 tank; added two gallons and now starts every time, runs at fast idle for about 10 to 20 seconds then dies flat or sputters for a while before dying. Currently suspecting fuel pump, throttle body gasket or throttle position indicator.

I removed the pan to change the fluid and filter.The pan was very clean,no trash,shaving,shrapnel.Does this truck have two separate pumps for forward and reverse?

None of the rebuilds last more than 100 miles.Their saying that its something else wrong.Would the computer have anything to do with breaking these pumps?They told me they put anew converter new valve body and still i dont feel safe.It shifts hard some times.and just does not feel wright.should they just replace the whole dame thing.I am out of toes and made as hell they cant get this right.

No noise lights on all the time changed transfer case switch motor and push button

This is 3rd tranny In three month three different shops three towns put in reverse you feel it go in but won't move so I think it has to be something else not the actual tranny what else and where could the problem be goes forward in all gears great no problems or delays in shifting just reverse and never heard any noises put tranny 3 in and never moved in reverse

i replaced the alternator and the battery. they are new. the truck dose not stay charged up
