Fuel Questions (starting) (searched)
 

Okay. So I took my car into a shop to get emissions work done. I get it back and its like its not getting enough fuel in the higher rpms, so I played with the 3 screws that adjust fuel. I pissed it off, it floods now when trying to start it. But it runs better =). Anyways I'm trying to get this right. I dont want to have to "try" to start my car, if it doesn't work, I unplug my fuel pump from my trunk (vert), try again, get the fuel out, plug it BACK in, and start it. I want it to start up like it used to again. But I think it was running too rich before because I was getting REALLY bad mpg. like... a hundred miles to a full tank on chevron premium. yes this is my dd. So what should I do? I dont want to just play with stuff because I want to be sure i'm gunna have it start right, have enough fuel to run hard, and have the mpg it's getting now.

What "3 screws"? Variable resistor, air bypass screw &...tps?

Find out what the shop messed with. No sense trying to guess what they did.

You do know you can pull the 40A EGI INJ fuse under the hood to keep the fuel pump from running while you crank, right? It's easier than digging in your trunk to unplug the pump itself.

Well my buddy work at the shop and he said the guy that worked on it adjusted it because it was running really rich. So I got it back and it was getting good mpg, but it wasn't getting enough fuel in the higher rpms. So i'm guessing he just restricted the fuel flow somehow.

When I pull the fuse, do I have to plug it back in when it starts?

So...they opened the AFM and adjusted the spring tension or something? Find out what they touched. That's the only thing I can think of that would affect fuel at high rpms (besides an AFC).

To flood clear: pull the fuse, spin the starter, replace the fuse, then start the car.

Yeah thats too much of a pain in the butt considering its not how it used to be. I just wanna play with it. I know i'm running rich, getting pretty bad mpg. But I dont wanna run too lean or i'll blow it up. I wish there was a way I could figure this crap out...
