Yes, i had the same problem. i've got a 93 isuzu trooper, but look in the chilton's manual, the engine and fuel systems are all for the most part identicle. My fuel pump went out, so I had to put it on a lift and drop the fuel tank. the pump is actually Inside the fuel tank. swapped it out along with the strainer, and now it runs like a dream. hope that helps.

How do I drain a trooper radiator

there should be a drain plug or tap in the bottom radiator tank. If it is a "T" shaped tap screw it in to open the hole. IF you can't find any sort of drain port remove the bottom radiator hose at the tank. It works fine but a bit more messy

Where is fuel pump located

Inside the gas tank. If you try to change it have containers handy - or another vehicle with an empty tank - to drain the gas into. It is MUCH easier to drop the tank when it is empty!

When its cold my 94 Isuzu pick up leaks fuel i think from the fuel pump. Now it wont stay running while idleing. should i just change the fuel pump?

Yes you should. It will not get any better. The seals are bad and with the fuel leaking, it will only get worse.

Want to find and replace fuel pump

The fule pump is located in the fuel tank as with most vehicles, the fuel keeps the pump cool and submersed in fuel. you need to undo both straps to your fuel tank and drop it and pull the fuel pump assembly out of the top. drain your fuel tank first though. hope this helps you!

Bad fuel has been used inthis car could this be the lamba senso

If bad fuel is used in this car, you will want to either syphon all of it out and pour in some isoheet or iso propyl alcohol. and change fuel filter. or drop the tank and change it or get all gas out.

Honestly, you should have tank changed and filter changed
