There are actually several things that ca be causing this behavior...
Since I have FEW specifics about your vehicle...
I'll simply tell you the best place to start would be your OBD
(on board diagnostic) SYSTEM... ought to be registering
good codes for you to start looking ... JUST REMEBER to look at the codes from a WHOLISTIC perspective... ASSUMING YOU ARE FUEL INJECTED... if a RUSTY baffle plate is bouncing around inside your muffler you are going to register multiple air-fuel codes...
(very well standardized by 1999 (I'm just saying)).
Because so much of your vehicle is run by computer now...
You have and added level of difficulty:
The fact that it restarts & runs immediately would make ME CHECK for loose connections in your fuel system, ignition... or collapsing or rusted out EXHAUST (mufflers and/or catalytic converters).
You probably need to purge the system,
Try turning the key on and off a few times without completely starting the vehicle,
This will send fuel threw the system,
It may take a few times to get the fuel pressure back up? try not to flood the system with to much fuel....
Hope this helps?
It sounds as if the fuel is taking a while to get to the engine possibly. A cracked purge canister could be the culprit, usually located right behind the headlight on the passenger side of the vehicle depending on the vehicle. It could be as little as a loose vacuum line but as bad as a weak fuel pump or failing injectors. Check for the vacuum lines first... A way to determine if its fuel related is to turn the key into the on position then off and then back on, do not attemp to start the engine yet, rrepeat this three to five times waiting a few seconds inbetween on/off intervals then attempt to start the vehicle.This is to give it time to build preesure from the fuel pump to the injectors. If it still hasitates to start its likely not fuel related. How long has it been since it has had a fuel filter change or tune up? Its possible for this to be fuel or firing related, but you said it runs fine after it starts so I figure its feul related. It seems the fuel is draining out of the line which lead to me thinking it may be the purge canister or a vaccum that may be running to the purge canister itself. Let me know what you find or dont find and I will attempt to help you further. Good Luck!
This could be any number of things. To get you started, you need to make sure its getting good spark and fuel. What does the engine idle like? Is it rough? How old are the spark plugs/wires and fuel filter?
check the fuel pressure. I will put money on a fuel pressure regulator leaking. The regulator is attached to the back of the CPI unit under the intake plenum. Fuel pressure should be 55-60 psi roughly and hold for a couple of hours. If pressure drops the first thing I would look at is the regulator.
You can also try this. Instead of trying to start the vehicle right away. turn the key to the run position, wait 5 seconds, then turn the key off. Repeat this a few times, then start the vehicle. If it starts right up than for sure you have a fuel issue and checking fuel pressure will be the next step.
The fuel pressure port is located on the back of the engine on the drivers side near the distributor.
All of the symptoms that you have talked about point to a fuel pump that is starting to fail. I would take it to a mechanic and have the fuel pressure checked. It is a simple procedure and should be rather inexpensive.
losing fuel pressure when engine is off and until the fuel system gets back up to pressure it is hard to start. faulty/leaky injector of fuel pump allowing pressure to bleed back into tank. also f/p regulator can cause problem too.
2006 Durango turns over and won't start. After a few try's to get the vehicle started the vehicle will have no power. After sitting for a few minutes the vehicle will start.
Has anyone experienced this?
Turn the key without starting the engine, you should hear the fuel pump engage. Do this a few times to prime the engine. If it still doesn't start, spray "starting fluid", available at parts store, into your throttle body. It should start now.
