Might pull the plugs & see that they're not fouled. That's the extent of my knowledge on the new stuff

Sounds like the fuel pump is loseing its prime. To test it just screw a fuel preasure gauge on the test port and see if it still has preasure after you shut the car off. It should hold preasure for a long time, as in days after the car is shut off. If preasure goes down it will take a little time for it to pump back up after it drains down. Another less acuratre but easier test is to wait till you know it will have a long crank time and try turning the key to the run position for about 2 seconds before cranking, this will allow the pump to build the preasure back up and if it fires right up after letting the pump run a couple seconds first you know your pump is in the early stages of dying.

Fuel filter is not servicable on that, you have to replace the pump to do it. You can thank the democraps for that. The fuel in a return style system heats the fuel n the tank after a while and makes it evaporate and destroy th atmosphere so on the return less systems that all new cars have put the filter in the tank as part of the pump, luckily they tend to be very large capacity filters so they hold a lot of crap before they cause problems and usually the pump dies before the filter gets full of crap anyhow.

what in THE HELL do you possibly want to blame a political party for a fuel filter design you dont like for?!?! the filters in those do pretty much last a lifetime.they are a fabric design,and if the media was unrolled,is tens and tens of square feet more area than the paper element in a conventional style filter.id bet five that its not a fuel filter related problem.

I agree that the pump is likely losing its prime. Not sure I agree with the second test though. I don't know that it will actually build any fuel pressure until after it starts cranking. I did have a similar situation with my Durango, it wouldn't start with the remote starter until the second try. 1st try it was priming the fuel rails and on the second try it would start. Interesting test because the auto start uses a defined crank time. After changing the pump it started 1st time every time. Fuel pump is easy to change but you have to drop the tank, make sure you run it low on fuel, like 20 miles past 0 DTE. A couple gallons of fuel sloshing around when you are dropping the take feels like a ton of weight.

I just went out and timed my 2000 durango fuel pump and it runs 3 seconds after turning the key to run and then stops. After sitting two days you can flip the key from off to crank as fast as you can and it fires right up. Most modern fuel systems will hold preasure for days or weeks or even months, I have pulled apart fuel systems in junk yard cars that have been there for a long time and had gas spray on me.
I just said that about the dems because they are the ones pandering to the greenies to pass stickter emmisions laws such as this one, would it make you feel better if I blamed the greenines instead?

You could say it however you want as long as you don't bring politics or religion into it. That tends to get things locked up around here. I'm just saying...
