To start off my 2005 mini cooper dinnan s2 about 3 weeks ago started miss-firing after changing out the coils etc realizing that wasn't the problem BC the issue only happened under load so i thought it was a fuel line issue so we replaced the fuel filter witch was actually in very bad shape as we had gotten bad gas from a store that had just refilled the tanks, this didn't fix the issue so i changed out the fuel pump this actually for the first couple of cranks sent some fuel to the fuel rail but again didn't start the car or work continuously.

if you have any suggestions that would be greatly appreciated
