It sounds like an incorrect wire connected. Normally the glow plug wire would supply power for a short period and then the relay switches off.
I suspect you have connected this wire to the diesel pump.

Where is the emergency fuel cut off switch located on 1999 Isuzu trooper

no engine stated..
i guess you like to search on rumors?
there is inertial switch. but no country stated nor engine nor drive line.

first check for spark not fuel
the ECU cuts Fuel anytime it sees spark fail (3 ways)
to stop TV like crash and burn,
check for spark if its good x4 or x6 , (depends on engine size)
and if that is good, check that engine runs for 3 seconds on test fuel, if thats good? then we check fueling system.
we have posted this answer on ISUZU vast times.
and not one poster ever once, told what engine is there or they country.
or insert scan too
crank for 5 seconds, Got P03xx codes, that is the BINGO for no starts, right? ever scan a car? its a cheap tool all mech have.
and all savvy DIY have.

here is a power search in fixya.

I have an Isuzu Bighon 1998 3.0 Diesel Dotch Engine which i purchased second hand. It is absolutely great when the engine is hot. It has issues with starting especially after being parked for more than 4...

ISUZU HAS A RECALL ON LEAKY INJECTORS ON THAT TRUCK GIVE THEM A CALL The injectors use the engine oil at very high pressure to inject the fuel, and semi synth oil just can't withstand these high pressures for very long. It breaks down, loses it's viscosity, and then the injectors won't work properly.
Change the oil to fully synth, and you should see a huge difference. (Do both oil filters while you're at it too).
1. Injectors. Usually the electronics in them fail and cause a miss fire.

2. Injector Sleeves. Causing diesel to leak into the sump and in severe cases the oil/diesel mixture filling up to such an extent that the vehicle actually runs on its own, on the mixture. This can cause the engine to rev to the maximum until all the oil/diesel mixture is burned or the engine basically destroys itself.

3. Rail Pressure Sensor. If the E.C.U cant determine what pressure is at the rail the vehicle may not start or stop running . A fairly simple fix with only the rocker cover needing to come off.

4. Rail Pressure Control Valve. This controls the pressure supplied to the rail. Engine will not start if this control valve is faulty.

5. Turbocharger. A very unreliable unit. Seals usually go after 50000miles.

6. Dual Mass Flywheel. Seldom give trouble but I have seen a few that have. If the new flywheel is taken off and not put back in the same way as the old one (lined up via a half moon shaped mark) the engine will not start as the flywheel sensor will be unable to determine the position of the flywheel.

7. Throttle Position Sensor. Fairly troublesome. Usually no deteriation in driveability but will bring on the engine light.

The engine is a gem when running correctly but unfortunately its a rare occurrence. I think the 02 onwards models had a lot of modifications done to them such as improved injectors etc.

Yanmar diesel engine model#3007D003 powering a 6x4 cuts off.

My thought is that it is electrical, since it will not crank. I assume you mean that it will not turn over when you turn the key. I am not certain, but I think that if you have an electrical problem it may shut off the fuel supply as well. There is probably an electrical fuel stop on that machine. Since there is no spark plugs or electrical system to make the engine run, by shorting out the electrical system it will not stop the engine.

Engine starts but stops immediately. I have replaced fuel filters still same problem. Could it be fuel pressure regulator

If your engine is gas, not diesel, then it sounds as though your main injector is failing. It runs for a few seconds after starting because the cold start injector has just fed fuel whereas the run injector is "supposed" to take over, and doesn't.If your engine is diesel you may need to clean your glowplugs and have the injector timing checked. Thank you, Dana

Sounds like your immobilizer is activating. Try another key or you need to take it to a vw dealer for diag and adaptation.
