How to replace a fuel pump for a land rover discovery 1998 crawsherry @yahoo.com

this sounds like a failing fuel pump, this would cause low fuel pressure and that would account for the chugging as u call it, if the fuel pump has over or near 100,000 miles it is very likely that it is the problem, the pump is located inside the gas tank, if u replace it also check the fuel pump connector for burned contacts and replace the fuel filter or the manufacturer won't honor the warranty.

have someone pull out the EVAP cannister (under vehicle, near fuel tank. it prob. needs to be replaced. if you can open it up, see if there is alot of dust inside, if so, replace with new one.

I had the same problem with my 98 discovery ..on mine the stering is on the left side ....on the right side under the glove box on the harnes wire there is a smal blue thing 1/2 x 11/2 inch box ( HJ1 splicer) power from the fuse is going in there and jumps with the wire from coil,fuel pump relay and the computer.In my car that jumper was not making contact ..after i shorted all 4 wires the car just started up.

fuel pump. run the pump dry and it destroys the pump.

I had that issue and found out that I had to push in in slightly and tune the cover withthe other hand to get it tight. if you try to get it tootight it would come off again. Also the tow top hoses need to be intalled b4 you try to tighten the black cover or screw or what ever that is called!

Under the hood next to the firewall is your multi-function box. It controls fuel and other things in your truck. You can pull your fuel supply line loose at the back of the injection rail and have someone turn the key on to see if you are getting fuel. If you are not, you will need test for power to the multi-function box and fuel pump. If you don't have a basic understanding of how to test for power to these components, my advice will not be much of an immediate help.

LAND ROVER DISCOVERY II DONT HAVE FUEL FILTER, ONLY HAVE PRE FILTER IN THE FUEL PUMP

This site has a lot of information regarding your Discovery including pricing, specs etc. I suspect you can find what you need here:

I was going to write that typical fuel pressure ranges somewhere between 15 & 25# and would have been 12# low.
Guess checking before pretending expertise is wise . . .

 

The fuel pump must run constantly while the engine is running.There is a return for excess fuel back to the tank.
