I'm in the process of resurrecting an '87 Isuzu Trooper. (Using the transmission of my old '86 that had been sitting for an embarassing number of years). Both have the 2.3L carbureted engines.

The '87 has been sitting for several years as well and will sputter if gas was poured down the carburetor before turning the switch.

I changed the fuel filter and put ~5 gallons of fresh gas in the tank (after draining most of the remainder out).

I've tried pouring gas down the fuel lines to fill them and prime the pump and even the float chamber, but still no luck.

It seems that the fuel pump needs to be replaced, but am I missing something?

Thanks for your help.
