Frustrated I have a 95 Trooper it gets spark and fuel and still no go, I shut it of and the ignition was left on and drained battery. I have since put in a new batt and veh will still not go......????? any feed back??

Connect a fuel pressure gauge to the fuel line and check the fuel pressure. If it exceeds manufacturers specifications; replace the fuel pressure regulator.
Spark plug cables which have aged, and now have more han 1,000 ohms resistance per inch of length, also can lead to cylinder flooding; and should be replaced.

No its not full with diesel fuel this is a common shut off on the isuzu. Plus the valve are always noisy . The crank sensor on those go out easy.This may not be the problem.Go to the back have someone crank it ,or if your hearing is great as you crank it do you hear a hummin noise that will be the fuel pump if you dont then the fuel pump will most likely be your problem.If you hear a humming noise as you turn the key on the fuel pump will not be the problem.Now let check spark. do you have a tach on it (the RPM) if you do crank it if it bounces just a tinytiny bit you have spark and the fuel pump will be the problem. Most common Isuzu trooper failure the ignition module

check your fuel pump, mass air flow sensor, crankshaft sensor, spark plugs, spray starter fluid in your air intake and try starting your car if your car starts then shuts off then your fuel pump is bad if it doesnt start up at all then that means your fuel pump is good and something else is wrong with your car. Fuel pump are some of the mian causes of a car not starting but remember only do this if the car is cranking and not starting if your car is not even trying to start then its your starter.

If it was mine I would get as much of the old fuel out of the tank as I could.(syphon or look at tank for a drain plug)Change the fuel filter.Fill it with fresh fuel.Add a bottle of (Red color) STP fuel treatment.This will help remove condensation form the tank.Also check the condition of the air filter and install a fresh set of spark plugs,properly gaped.
The octaine in you old gas gets weak. Its not good to let it sit for so long.
I hope this helps you.

Could be fuel pump, is the pump running when you turn key on, you should be able to hear it. You are likely going to have to take it to someone with a pressure gauge to make sure it is getting proper fuel pressure. Fuel pumps commonly go on these vehicles

usually with a special gauge-n to chec for ignition take plug out with wire attached and turn car over-a little but the best thing is to get a haynes manual at a discount place

did you unplug the battery when the work was been done allowing the car main cpu system to reset itself if not u may have to go to a dealer of your car to have them reset cuz car computer doesent know work was done

you probably have a build up of "gunk" in the fuel pipe or injection system, the popping and stalling when accelarating could be tied to this (the valves probably gunked up) their is a kit wal-mart has that may help its a fuel injection (carb) cleaner the kit you can do at home and comes with directions or it can be done in the automotive garage.

well honda's are natorious for the computers going out also check the ignition relay,fuel pump relay,make sure it is getting fule.also check the timing belt

have someone kick at the gas tank while you are turning key if it starts it is fuel pump
