It should run for 2 seconds and you should have a solid SES light.

Yep got the sets light but no pump .

Hi Dylan if it needs a tune reloading is that something that can be done on the aldl or does have to be burned

When everything's working right it can be done over ALDL with our 12P code. But a burner may need to be used otherwise. Maybe you could fit a stock memcal from a 165 to see? So long as it doesn't run VATS.

Thats a good idea. Unset the rw jumper if its set first though just for that protection incase its ok now. If swapping to stock memcal gives you pump then you need to write the nvram chip in a burner to bring it back to life. Be real careful getting it out the socket as its tight for a good connection but tends to jump out after a point which can bend the last pin.

Fuel pump prime is not software controlled on the '808/'165/'3082, can have no memcal plugged in and it will still prime.

I've had failed ecu's behave in very similar ways

What's the correct pin out for the aldl /obd to connect a pc to read 12p all so having trouble finding comport 6 device manager on my laptop doesn't have it so can't get communications going can't get drivers to download

Ecm A8 to OBD pin 9. 12P docs call it "primary serial data" . Ground to obd pins 4/5 and B+ to obd2 pin 16 (not required, but recommended).
