Re: if trooper has no oil will it not start
There is no safety device from keeping you car from starting up. You have a low oil pressure light on the dash that lets you know when your oil is low or there is no or low oil pressyre. So keep an eye on that oil level The best thing to do is every once in a while visually check the oil with the dip stick because no oil = siezed engine and you don,t want that. I hope this helps. Don,t forget to rate my answer, thanks.

Did you repressurize the system after replacing the fuel pump? THIS IS THE MOST COMMON ISSUE. You must cycle your ignition switch from OFF to ON several times before first start after depressurizing the system;
Has the vehicle been bumped hard, violently jarred, or in an accident? RESET THE INERTIAL SAFETY SWITCH;
Are you getting correct fuel pressure? If not, replace the fuel pressure regulator.
Based on your description it sounds like worn valve guides. Oil will seep down the guides over night and when you start the engine the oil is burnt off. Pull a plug and look for deposit build up on the plug. Sort of a brown residue built up on one side of the plug.
check out the neutral saftey switch on trans, if its reporting unknown gear on scanner while moving t bar it wont know what gear to be in and give you similar problems, also has oil been leaking into switch before?
Check the safety switch above the clutch pedal. If it is adjusted properly, you can test it by pulling off the connector and shorting the connector terminals together with a paper clip. If the car starts OK with the shorting pin, buy a new switch. Any questions, please reply.
I HAVE A TROOPER 3.O L THE SAME AS YOU AND I KNOW THAT WHEN CHANGING OIL YOU MUST USE 5-30 OR 5-40 FOR THIS ENGINE REASON BEING IS THAT THE OTHER GRADE DOESNT CREATE THE SAME OIL PRESSURE AND IF THE OIL PRESSURE IS NOT CORRECT THESE ENGINES WILL NOT RUN BEEN THERE DONE THAT
Classic Trooper problem. You can get a lot of quiet(er) troublefree miles out of your Trooper with religious, regular oil changes. Isuzu is now advising the use of Mobil 1 0w30 synthetic motor oil, changed at 5000 mi intervals to quiet the lifter tapping that you're experiencing. If you're a DIYer, you can pick up 5qt jugs of this oil at Walmart for $23-$26. -Or, you can buy the basic oil change and provide your own Mobil 1 0w30 to the tech to keep the costs down.
It'll take 150-300 miles for the noise to settle down after the fresh oil change. Keep a close eye on your oil dipstick. As soon as you're coming close to a quart low, top it back up. The 3.2l motor will start tapping again when the oil level drops or is near the time to change. Forget the advice about the belt tensioner needing to be replaced. That is rarely the source of the noise. I have two Troopers, Christophe. They're the ones that aren't tapping like crazy at the traffic light. Enjoy your Troop. -Geoff
engine oil leaking past injector O rings and going into fuel return hose back to tank contaminates tank. if recall done are O rings ok? can put clear plastic tube on return fitting in rear of head to see if black (contaminated with oil) or air leaks, from cold start, it isnt high pressure
it could be from before or now?
