Is my fuel pump going out?

[indyblue]

Every time I see these threads, I start missing my old 60s cars all over again.

Simpler times...

Touche'
I will never miss mine 'cause I kept it

15 minutes to change plugs + No points - now Pertronix + no computer/blackbox = PRICELESS​

There's also no place to plug in a stupid "Snapshot" for insurance.

I'd check fuel filter & ODBII codes first. (EDIT - I see these do not have replaceable fuel filters, they are integral to the pump)
It sounds like it's harder to start because of fuel pressure leakdown over time.
Crank or CAM position sensor could be culprit too.

some fuel systems will have a check valve in the pump that will leak by and let the fuel pressure bleed off. When that happens it takes a bit for the system to built pressure to start the car.

Best way to check it is put a fuel pressure gauge on the fuel rail, let it sit overnight (or longer, what ever works), and see what your fuel pressure is. Typically fuel injection systems run around 50 psi +/-.

If that is the case, it doesn't mean the pump is bad, and you could live with it for a long time before its fixed.

See, I don't buy the check valve issue. Nearly every fuel injected car that might have something like that will still have the pump run again at key-ON to repressurize the fuel line/rail.

If you want to entirely eliminate that as a cause, try using a couple of ON-OFF-ON cycles prior to the ON-START cycle. That should ensure that the pump runs a few times and even if all the fuel/pressure from the lines/rail is gone it should have plenty of run-time to repressurize.

you don't have to buy it, but I've had it happen in two different cars

Yeah...but you have crappy Chrysler vehicles.

Small update:

this is my car starting up this morning after having been off (And garaged) for 13-ish hours.

If you can notice the video shaking as the car is cranking - yes, it does shake that bad. But only after it cranks over for a bit.
