2.5 16v stalling
I just put 10liters in
It ran fine when loaded and unloaded 2 times from flatbed trucks.
Ignition off
3-2=0
6-2=12.21
Ignition On
3-2=3.62
6-2=11.95
Engine on cold
3-2=6.83
6-2=13.60
Then stalls.
The pump is really noisy. Bet the filter or strainer is plugged.
It's still on the flatbed so working on it there will be a challenge
Looks like it's running rich. But that wouldn't cause it to stall.




No error code on the X11 port.
What is the coolant temp when it stalls?

I ordered a new filter.




Also check the filter screen at the input port of the fuel distributor. That is your last defense and you need that to be clean before and after all the flushing.




I ordered a new filter.
I don't have an air compressor at home so all I can do is frequent filter changes until i can get it to a shop.

I thought the PO installed new pumps and strainer but that is looking highly unlikely.
Had similar issue on 1986 2.3 16V.
After replacing and adjusting various things for 2 years, brought the car to https://www.precisionautocenter.net/ . Felipe checked car and determined the throttle body was the issue. He sourced one, put it in and the car starts and runs perfectly.

My car never sat for more than a week or two and has been a daily driver for 33 years. Even so, I swapped in a spare accumulator when I changed the fuel filter a year or two ago and there was water in the return rubber hose between the accumulator and the tank. There is no flow there and it is a low point in the fuel system. Just an example of what happens with sitting fuel.
Hoping you have success in cleaning up the fuel system.
-Cheers!
