hy

my s2 wond't pull hard on load or on higher rpm
and the sparkplugs are white

could this be a weak fuel pump?

Could be. You need to check your air to fuel ratio when on hard acceleration. The car could be running dangerously lean.

 

i don't have an air to fuel meter.

the car starts from the first time and hold's boost like normal
butt when you accelerate it hold's back

a few weeks ago i did ran out of fuel and the fuel pump made a lot of noise ( could this have kill't it?)

It could have. You could check your fuel pressure (if you have a fuel pressure gauge)...

 

nope i don't have one

the car was running fine before it ran out of fuel thad time

are there some other things i chould check before i replace the fuel pump ?
