Fuel Pump/Filter or something else

[bearpaw]

A little trick we have learned for dealing with in-tank fuel pumps in suburbans and tahoes, look under the truck and locate where the fuel pump is at on the tank, lift the carpet in the vehicle and cut a hole in the floor right above the pump, makes changing a fuel pump very easy. To plug the hole that you cut out, just cut a square piece of tin to cover the hole, screw it in place, lay the carpet back down. You could probably do the same thing with a pickup to save a lot of hassle if you don't mind a patch in your truck bed.

I have heard you can give it the hillbilly test. Tap on the bottom of the gas tank some and see if it will pick up some fuel and run for a short time.

Sometimes you can beat on the fuel tank. Jarring the pump motor might make it work....same idea as hitting a starter with a hammer.

As an added bonus, it just feels good to hit it with a hammer when it doesn't work!!

Fuel pump on my Tahoe went at 165,000, so probably the most likely suspect as it does seem to be a Chevy thing...

I put 2 in my '02 Silverado in 235k miles. Used to work at a GM Dealer. It's a Chevy/GMC thing.

I had a 2000 silverado 3500, same story, two fuel pumps in 240,000 miles, you can tell when they start whining louder they are getting ready to self destruct

Older Subaru  wagons  had this hatch built in from the factory.

This thread has reminded me to put an access hatch in my Jeep Cherokee before I  roll some bead liner in the tub!

There's a bunch of vehicles that have them. We're doing fuel pump recalls on Escapes right now that have access under the back seat. Can't remember what Chrysler cars have access in the trunk if I remember correctly. There's a few.  Some techs will lift the bed rather than drop the tank on pickups. 6 one way, a half dozen the other probably.

I put a access hatch in my Jeep Wrangler when  I had to replace the pump.

Did this in my 94 chevy pickup. I have a bed liner so I never see it anyways. Youtube is your friend. Easy-peasy

You should be able to hear the fuel pump if you are down by the tank and have someone switch the key to accessory. It should have a high pressure rail, I would not recommend taking off the fuel line to test fuel flow!  Probably a pump, 200k mil s is well in the range for a failure. The failure to turn over has me a little worried, that is not fuel related. Lack of fuel should have let it turn over as normal, just not start.

Timing chain or belt is a possibility, though hopefully not.

electric pump in gas tank not engine compartment, key to run and listen... there may be a tip switch but not sure on that model.. either way, my money is on the tank pump for starting point

You can always double check if the truck has a fuel filter, which it might. It’s located on the driver side frame rail adjacent to the tranny. Start easy and then go difficult😁 and for gods sake don’t use ether to spray in the intake. Some people don’t know how much is too much. It’s a good way to crack a piston ring. Good luck!

I checked the mass airflow sensor and at first I thought it was it. I unplugged it and it ran for about 20 seconds until I turned it off. Then I went to get a new one and it wouldn't start. Back to square one. i had my buddy turn on the accessories and the fuel pump was not making any noise...so went and got a new fuel pump. Lifting the bed off was the hardest part, couple bolts gave me a tough time. Now truck is running great. Thanks for all the input!

Glad you were able to get it repaired.
