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 may be entitled to injector set under warranty. All 01 troopers qualify

My 2004 kia sorento 2.5 diesolhas plenty of fuel turnd over but will not start

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.

Driving down road in blazer and it shuts off. Won't crank up. Plenty of fire

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?

Engine firing order

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

2001 cavalier wont start cranks but wont catch then it caught one or two times then shut right off has plenty of gas

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.

Wont start plenty of power sounds like it wants to start but wont fire tried listening for the fuel pump but no sound tried pouring gas directly in it and still no fire

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.

I have a 1988 toyota pickup with the 22re motor it has plenty of spark,and turns over but wont fire i also replaced the fuel pump and still nothing what else could it be?

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.

93 astro van turns over has juice but wont fire

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,
