First what kind of Isuzu. Usually it would be GM motors that fit
the fuel pump is in the tank. u have to drop the exhaust then the tank
This has a r134 system after 1993 was made standand industry wide to quiet the epa issue with r12
It will be a 305 or a 350 fuel enjection engine ( TBI )
That year Dodge should have fuel injection
THE FUEL PUMP ON THE 1986 ISUZU TROOPER 2 GAS 2.3 ENGINE IS LOCATED UNDER THE INTAKE MANIFOLD. YOU CAN GET TO IN BY TAKING OFF THE FRONT PASSENGER WHEEL AND RUBBER GARD AND YOU WILL SEE IT. I HAVE ONE OF THESE TROOPERS. HOPE THIS HELPS.
a GM product
I am sorry to say that there is not a cutoff of any kind.
It's an old trick to clean out the injection system, BUT... it's not advisable for all vehicles, especially diesel engines with an aftertreatment system.

If you can run a voltage test to make sure everything is working you'll find that it has a very low voltage simply because your unit is submerged in fuel. But this will tell you that your ECU is receiving some kind of signal; however, what is being outputted is different so you need to take your rodeo to a Isuzu dealer and even tho a passport is the same car Honda dealers can't do it. An Isuzu dealer can be hard to find at times because some dealers will sell Isuzu but not be certified Isuzu dealers, I know that sounds wierd. Anyways If you've replaced it and checked the wiring and know everything is ok then there are 3 codes that need to be programed into your ECU to fix your fuel sending unit and this can only be done at a dealer
