P1000 21 Pioneer 1000-3 dies 10 seconds after starting

[jsiron]

21 Pioneer 1000-3, bought new, has 450 miles, garage kept, only water has been a little rain and a garden hose. Started with a random low idle and would occasionally die. Quickly progressed and now will only run for 10 seconds after starting every time. Blink code 13. Has new, fully charged battery. Checked, cleaned, and made sure all grounds and positive connections are tight. Ordered injector plug kits and installed. Checked voltage at injector and it doesn't lose power when it dies. Have not switched injectors to see if it follows. Barely got it out of the woods and next time off trailer is at the dealer service dept. Thought I'd see if anyone had any other ideas or directions to point me in.

If injector wiring repair kits did not solve your issue, swap your pgm-fi (computer) with a known good. The injector driver circuit may be damaged.

Could the iacv be causing it? You said at first the idle was progressively getting worse. Maybe it needs looked at. Or maybe fouled plugs.

Thanks for the response. I will have to rely on dealer as I do not have a known good one.

Early before it started dieing I noticed rpm was ranging a little, so I went down the fuel pressure and ignition route. Plugs look fine. Currently it starts and runs smooth as silk then cuts off like you shut it off. No coughing or chugging.

UPDATE:
I took it to the dealer. It was the PGIM-FI computer. Good call @Neohio. Cannot confirm cause, but from here on out, I will be very cautious of jump starting with an old high amp jump pack.
