Dies sometimes, Have to cycle key to start...2003 carvan 3.3L
Hello all!! i am having problems with my 2003 Dodge Caravan 3.3L.
In order to start the vehicle, i have to cycle the key about 4 times or so to get fuel pressure for the van to start.
any ideas on what this could be? im thinking one of my fuel injectors is sticking open, and im losing fuel pressure.

- I have taken apart the fuel injector wiring harness and noticed some melted wires, and fixed them. didnt help at all.
- The fuel pump has been replaced 2 times thinking it was the issue

Are you checking pressure while this is going on to confirm it's a pressure loss problem? Here's what's bugging me. Given that statement alone it sounds like a pressure problem. Add your second statement and it gets foggy. A leaking fuel injector or fuel line usually doesn't cause intermittent stalling. Add the fact you've changed the pump twice and it gets even more foggier. Your two symptoms may or may not be related. I would check the pressure using a gauge and do all you can to confirm the pump isn't loosing power. A meter ride along or complete harness shake test may do it.

I would love to check the fuel pressure, however my van model (2003) is the first year they made the 3.3L without a fuel rail port. i would have to order an inline testing tool. Which would be $55.
I think maybe my melted injector harness ruined one of my injectors. Im going to order a set of injectors ($80) and replace the intake gaskets ($19) while im at it.
If it were a fuel line, i think id see some fuel on the ground or smell something. There is a strong fuel smell on initial start-up also.
will update

Update!! I just changed my upper / lower Manifold gaskets, and all 6 injectors. No change at all :/ maybe the person who changed the fuel pump both times, did it improperly?
So the van is still daily drivable, but if it sits for longer than 30 minutes or so I have to cycle the key 4 times for it to start.
