Fuel pump wiring diagram for 1998 chevy express. gas tank when dry, clogged fuel filter. changed fuel filter and van started he let it run out of gas again but now gettin no power to fuel pump. there is power to the relay though.

2 of them........First Fuel Filter

One fuel filter is in the fuel pump of the Express Chevy 3500, which is used to push fuel or gasoline through the fuel line. The fuel pump is inside the gas tank. This fuel filter is a mesh or screen that prevents large foreign particles for entering the fuel pump. Access to the fuel filter is obtained by removing the fuel tank and then the fuel pump from the fuel tank.

Second Fuel Filter Location

The second fuel filter is within the fuel line itself. After the fuel pumps extracts fuel from the gasoline tank and into the fuel line, fuel flows through the line and through another filter on the driver's side of the Express Chevy 3500 under the front wheel suspension. This fuel filter cleans the small particles that escaped from the fuel tank.

Fuel Filter Types

The year of your Chevy Express 3500 determines what type of fuel filter is installed on the van. The fuel tank filter is always mesh or screen, but the fuel line filter can be of three different types. Two types are snap-on filters, while one type has clip-on ends.

1998 Quest is fuel injected. New fuel filter is good but you may need to change it again after checking for plugged injectors. This is not a fun repair to do on side of road. It is possible that fuel lines may be clogged depending on how nasty the fuel in the tank was, especially near empty. The fuel strainer, in gas tank, may be corked up as well.

What is a "crunk"

not enough fuel pressure check filter could be bad pump

the fuel filter should be on the drivers side under the van in between the fuel tank and the motor. Usually about where the transmission is on a 2000. It is not in the fuel tank.

If you change the filter every 30-36 thousand miles you will get the most life out of you pump. Most of them fail around the 100,000 mile mark when the filters have never been changed. I have seen them go as long as 300,000 miles with regular filter changes.

$8 for a filter, $300 for a pump. you can buy a lot of filters for $300!

hi might wanna check the fuel filter , if that's clogged gas wont flow threw injectors. theirs prob ly two, one under the carriage one by the motor thanks

1st ensure the fuses are all good and there is fuel in the vehicle and your not getting a false reading by tapping on the tank ..does it sound Hollow oe Empty / another way is turn on the key and listen for the pump to work a slight humming should be heard ...if so locate the fuel bar and cap screw depress the valve shielding your eyes with say a towell and see if gas dispurses make sure the key is on while doing this if no gas is there or fuel pump is heard then it may be either a bad ground to the unit or the fuel pump itself corroded connections will contribute to this as well unclipping and reclipping the connection togeather should allow a better connection

i had a similar problem and called the dealer during lunch hour. i talked to a mechanic, the distributor in these vehicles is plastic, and is prone to cracking.not just the cap but the body also, I have been taking the cap off and wiping the moisture out of the cap. or replacing the cap but the problem is I need a new distributor. just a cheep way to get rolling is cleaning the inside of the cap, especially when it is very damp or the outside temp changes alot during the day. good luck.

Best do a fuel pressure test. Should have chg. fuel filter from the get go. The only other filter is on the end of the fuel pump in tank. Bad gas and dirty gas will plug up fuel filter, hense burn pump up.

Some fuel tanks have a drain **** that will allow you to drain all of the gas neatly. If you have a drain ****, it will be located at the lowest point on the tank. Loosen the valve and allow the gas to completely drain.
If your tank has no drain ****, you'll have to drain it by removing one of the fuel lines. The rubber hose that exits the tank at its lowest point will drain the tank fully. It will either be connected to an electric fuel pump, fuel filter, or to a hard fuel line that goes to the front of the car. Loosen the clamp on the end of the line that connects to the gas tank. Pull the hose off and allow the gas to run out of the tank into your container until it is drained completely.
