sweet. thanks for all the info. sorry if im being annoying about it, would just like to have it run properly lol.
No problem. If it were me I would disconnect and clean every connector. When you turn the car on or when it is running do you see a mileage on your odometer or just dashes ------?

Additionally. You want a donor car as close to your year and model as possible. ECU's are available on Ebay for $175. No way to know of a junkyard ecu is any good. Was the car professionally dried out? Does it have a salvage or a rebuilt title?

I'm really starting to think you have a fuel delivery issue separate from your electrical. There are 2 kinds of fuel pumps. One with spring loaded legs and without. If you use the wrong pump for your tank you will get fuel delivery issues just like you describe. The other possibility is the vacuum line to the fuel pressure regulator or the fuel regulator itself which is on the fuel rail. Pull the vacuum line. Check for a bad vacuum line or fuel coming out of the regulator.

when i took out the pump it did have the spring legs on it, then i replaced it with the one without. since i work at a parts store was able to determine the spring one was for the older focus and i think it was 03 they switched to the ones without. im getting fuel through the line when i disconnect it on the regulator but i havent checked if any comes out after turning the key and it feeding into the regulator.

You have fuel coming out of the vacuum line at the regulator? If fuel is coming out of the vacuum line at the regulator, the regulator is bad.

I'll check when i get home. If that's all it is I'm going to be so excited lol one through work is $105 so i might be able to pull one from a car at the pull-your-parts for now. I've seen the vacuum line that comes out of it and doesn't look like the easiest thing to get at.

Pulling the whole fuel rail may be the best option. Good time to replace your injector o rings. You do need a spring clamp tool set. Plastic collars that slide around the fuel line. You push in to release the spring clamp. Can't get the fuel lines in the engine compartment apart without the special tool. Pretty cheap.

luckily i don't need that tool. every fuel line i've come across has just had the plastic clip you squeeze and they slide out of the way. so much nicer lol.
