Take a fuel pressure gauge for a ride --tied to wipers

See if your loosing fuel pressure when it quites ,or see if
that data is avail on scan tool

Some brands of pumps don't last long,so I heard & see from
other experts on here

I guess a relay for fuel pump could have a bad primary coil in it

Try switching them around-- to something else you don't need
all the time

Check fuel flter at fuel pick-up intank (looks like a small wire sock). Remove fuel filter and fitting at fuel rail. Blow out fuel lines w/about 35lbs air press. Ck electrical @ relay - should be 4 connectors - one is key on hot/one is always hot/one is ground and last is hot to fuel pump. Good Luck

could be the injectors are worn, the fuel is not atomizing. dribbling more than spraying.

SOURCE: "Cranks, but won't start". Replaced fuel pump, CKP, ICM & nothing

If the engine cranks over normally when you attempt to start you car, but the engine does not start, the problem may be NO FUEL, NO SPARK or NO COMPRESSION. The engine needs adequate fuel pressure, a properly timed spark and normal compression to start.


1) To find why the engine won't start, remove the air inlet tube from the throttle body, push the throttle open and spray a small amount of aerosol starting fluid into the engine. Crank the engine. If it has spark and compression but NO FUEL, it will start and run a few seconds before dying. If it does NOT start, it probably has NO SPARK.

2)Another method to check for spark is to pull a spark plug wire off of a spark plug (if it has plug wires, coil-on-plug ignitions do not) and place the open end of the plug wire near a metal surface on the engine. Have a helper crank the engine while you watch for a spark. DO NOT hold the wire while doing this as it can shock you. If you see a spark, the problem is not spark, but most likely NO FUEL or NO COMPRESSION. If you do not see a spark, the problem is in the IGNITION CIRCUIT.

3)Proper fuel pressure is critical for fuel injected engines to start and run. You should hear the fuel pump inside the fuel tank buzz for a couple of seconds when the ignition is turned on (no buzz means the pump is not running and the engine is not getting fuel). You can smell the tailpipe for gasoline vapors after cranking the engine. If you smell gas, the problem is likely not fuel but NO SPARK. You can also remove the plastic cap and press the schraeder valve test fitting on the fuel rail to see if there is any fuel pressure to the engine (not a very accurate test because fuel pressure must be at a certain level for the engine to start, for that you need a gauge). Even so, no fuel at the fuel rail would tell you fuel is not getting to the engine..

It is possible that your cam angle sensor is on its way out. Have it checked asap, it will choose a lonely, deserted road miles from nowhere to finally let you down.

I HAVE A 99 DURANGO AND WHILE DRIVING DOWN THE ROAD IT JUST QUIT. AND NOW IT WON'T START .


If engine is turning over my first and cheapest Thought would be to change the fuel filter(assuming your not out of gas). If your somewhat mechanically inclined (or know someone who is) you can spray some starting fluid or splash a little gas into the carburetor and if the engine fires a little bit that will be it.

It could be other things (fuel pump) but without additional info I say start there.

Do you smell gasoline fuel ?? When there's too much fuel, it saturates the spark plugs, preventing ignition. Let it sit for an hour to let spark plugs dry, then it starts OK later. Next time, turn starter without giving any throttle or very small throttle as engine turns. Myself, when my 2006 Dodge Plymouth minivan (sitting in storage) needs to start, I squirt (half second) starting fluid into air filter, close the air filter housing to trap flammable gas from starting fluid, then turn the engine without pressing on throttle. When the engine starts is when I give it a little throttle to bring up the RPM to 2,000 until it idles on its own without stalling from cold engine.
