I have a 97 Land Rover Discovery. I haven't driven it in a week or so. I took it out today and could not go over 15-20 mph. It sounded like my fuel pump was knocking? Is this a common problem when the fuel pump is bad?

 

I've never heard of that, but suppose possible something may be loose in there?

Could it be the noise was coming from the exhaust at the tail end, like a miss or sputter?

 

I'm not sure. Its a brand new exhaust system. What else could be causing the problem I'm having if it isn't the fuel pump?

 

If it started right after the new exhaust was installed, then the exhaust is the problem.

 

maybe, the purge valve? Have the codes read?

 

It was happening before the exhaust was installed.

 

I remember when I had the exhaust put on and the computer reset the mechanic said something about the fuel pump but I cannot remember exactly. It was something about the float maybe?

Would it say it was throwing a code?

 

check your fuel pressure. It should be between 34 and 37 psi a idle. Could also be a bad fu pressure regulator.

 

It is weird. I started the truck yesterday and it drove fine. Stupid Land Rover!

 

Rover11-- it must be the F U regulator Dodger was talking about. Nothing to do with the Fuel Regulator but that other, special F U regulator which meters out an occasional F U as preprogrammed by those fine chaps at Solihull.

I think Lucas makes all sorts of F U components too. I think I'll see if I can order up a "Special F U Vehicles" badge for my rig.
