this is not an obd2 engine. obd1 is all i got. and my blinky light shows everything is working 'correctly'.

tried a few other things like bypass the fuel pump relay and main relay giving them both their own battery. so i know everything is getting power.

tried unplugging the maf and tps while in these states and nothing happened.

i also found a pin that is a 'california identifier' pin on the ecu. this is not supposed to be grounded but it was. This, now that i'm thinking about it, doesn't make sense because it is routed right to a ground from the get go meaning it was grounded in the old legacy it was in for the first ~18 years of its life... Anyways... didn't make a difference...

Also sounded like the fuel pump was struggling a bit while it was pumping (because i bypassed the relay i didn't prime anymore, just on all the time) so i put another 5 liters in it and it smoothed right out. wouldn't it be nice if it turned out i just didn't have enough gas? well it wasn't that easy i guess because it stayed the same. My fuel pressures are a little more smooth now but i still see the same results.

what the hell is going on...? i've got it running SUPER smooth then it's like somebody is jacking my keys 5 seconds later.
