Hey peeps here we go ive got a ls hatch It was running great for months then it start sputering and gives a cel for code 43 fuel somthing i thought well the car has a gazillain miles so replace fuel pump and filter now it stalls when i get on flat surface
Ive tried a new relay im gona take fuel rail and injector off see if i can test and clean them other than that it just got a nw dizzy about few months ago had it got timed plugs the timing works help im stuck

 

Does it start? Does it idle? Can you drive it? How much gas do you have in the tank. You need to be more specific...

I can't excatley (sp?) tell you what is going on. So you can drive fine on uphills and downhills then? But when you go to a flat surface it stalls?

 

yup it starts but only when facing uphill any toher than that it stalls ive got a half tank if we rock the the car back a fourth itll start weird but

 

You should check continuity between fuel injectors and ECU pins. I had this same problem and the car ran like butt. When I checked the Injector wiring, the #1 injector had like 8 ohms of resistance between the injector wire on the harness and the wire at the ECU. I ran a new wire and it stopped throwing the code, started running right.

 

What kind of fuel pump are you running? OEM or aftermarket? Any codes?

 

nope no codes k i got it to stay running but now it wont run under half a tank and when i stop kinda fast it stalls ohhhh it ended being the fuel filter what was stoping it from running on down hill slopes


Ya i put new napa pump in the guy said itsa a little better 4 the swap he said??
