2001 L300 3.0L V6 Auto - Won't stay running!
 

Current Stats:

Fuel Pressure: 40 (cranked) / 19 (key-over)
Fuel: 1/2 Tank
Battery: Working
Current Codes: None w/ Previous Codes (Voltage / Transmission [which has been on-going; causing intermittent shifting issues until code resets])
Current Condition: Vehicle Sitting after a Tow
Engine: 3.0L V6
Engine Mileage: 144K

What I have done since it's been towed:

A) Replaced all fuses with new ones
B) Checked the fuel pressure (40 cranked) / 19 with key over
C) Oil change
D) Oil Filter change
E) Fuel Filter Change
F) PowerTrain Control Module (PCM) changed from stock "version II" to a Pick-N-Pull 03 LW300 "version III" which has been properly VIN Programmed via which worked perfectly as the expert explained.
G) Used an Oreilly's OBDII reader and cleared codes with a jumpstart from my kind neighbor Nichole.

It starts and looks as if it's going to idle; the service engine light remains on during this step; then it gets to 3000 RPM's when I am pushing the gas peddle a bunch before seizing. Can't seem to get past this part.

I checked again for the fuel pressure and created this video as to what's happening at this time frame of this repair.

Without knowing for certain; a couple things are popping in my head.

1) Could it be the alternator? Hence; the not being able to keep alive. (However; given the weak RPM/idle -- it seems as if it has something to do with something else.)
2) Could it be a sensor that isn't throwing a DTC code?

* Updated @ 19:41 - Also to note: The shrader valve puked a bunch of fuel upon removal as opposed to exiting the outpour tubing - Seemed like it defeated the purpose and I used a brand new fuel pressure kit from amazon. It wasn't necessarily cheap either. I was wondering why it would do that... regardless of the pressure readings.

Thank you!

Did you ever find a split? I have a random stalling issue with my 3.0 VUE.

Please start your own thread and we will try to help you

If you're just sitting there revving the engine and not going anywhere, it MIGHT have a rev limiter on it. Have you tried just driving it up the road and seeing if it will go above 3,000 rpm? I had a PT Cruiser Turbo and thought there was something wrong with it when I couldn't rev it past 3,200 rpm with it sitting in park. Turns out, it had a rev limiter on it! Boy, did I feel stupid!!!!

I do actually have my own thread for my issue. But I noticed that no one had commented on his, so I was curious if he had found a solution.

Problem solved.
I saw this before I saw your thread.
