9 times out of 10 the problem is the fuel non return valve not shutting off properly and the fuel runs back from the pump and injectors....needs to be replaced .About €80. Ring isuzu and give them chassis no...you may be entitled to injector set under warranty. All 01 troopers qualify

When you say plenty of fuel...where is this plenty of fuel?
remember Diesel engines fire from the heat of compression - not spark. Also, fuel may be getting to injector pump but pump may not be working correctly.
They have been making blazers since the 1960s so i do not know if it is FI or Carb? I take it you mean cranks but won't start?? If you have "plenty of fire" it has to be a fuel problem.. Possibly bad fuel filter, pump shutting off, bad pump relay.. trash in tank clogging fuel pick-up.. Check for fuel pressure?
If the leads or not correct for the firing order you will have a pronounced miss/ back fire or hard to start. If the fuse to the fuel pump keeps blowing then the pump is shorting out or is drawing too much current in it's operation. Acceleration will demand a plentiful supply of fuel and if the pump is having problems replace the pump . have the fault codes read and have a fuel pressure test done on the fuel manifold to check -filter and fuel regulator operation
More than likely a bad fuel pump. Take a rubber mallet and take a few upward strikes on the center of the gas tank (infront of rear tires in center of car). You should be able to reach from reach without raising car. Than try starting. If it fires and runs a few seconds where it wouldn't fire before striking the tank. You need to replace the fuel pump.
under the hood is where you will find the fuel pump relay,just above the brake booster you should find two identical relays there try swapping them and see. if it helps. if not you will have to test the power source at the rear up by the tank is the plug, for this you will need help , have someone turn the key while you use a test light to see if power is being delivered. you will only receive for 2 seconds.if power is ther check the ground if ground is present then pump is bad.
Im wonderin if some of that water got into the cylinder area and bent a rod ruining the compression--did u ride thru a flood zone--mite want to do a test--also scan vehicle and test injector pump off engine
Check all the fuses,and check the fuel pump relay,if this checks out o k,See if there is fuel pressure at the fuel injectors,if there is,then the injectors are not pulsing.The cause of this is the pick up coil in the distributor,but replace the distributor as a whole,this has all the components in the distributor,That control the fire,and the pulse to the injectors,A used one might be more economical sound money wise.
a real quick way to test your fuel pump is to take a rubber mallet and have some one crank the engine while you beat on the bottom of the gas tank if your vehicle starts you have a bad fuel pump and it should be removed and replaced with a new one,
