BPT question

A new fuel pump should be a given. Get a walbro it will do all you will need ( they are like $75). Make sure you are at 10 degrees timing and your fuel pressure regulator is good.

What do your plugs look like?

Have you replaced any ignition parts?

a little whiteish Ill try and get a pic, just the spark plugs and wires were changed.

You my friend need to get a fuel pressure guage to see whats up. Something is causing your engine to starve or lack fuel in the cylinders. If your timing is straight I would say your fuel system is the cause.

jon has the right idea. use the wideband to check and tune your a/f ratio. if it is showing lean, you could try adjusting your VAF, then if that doesn't cut it, you might have to get a high flow fuel pump. I'll give you the link again to those ones i found online.

widebands are the best thing to have for anyone trying to get the best efficiency from their setup.

i talked to bcowie yesterday on aim, it sounds like the VAF that he is using has been opened, so it was probably screwed with.

did you get to test the voltage signal from the VAF yet?

[bcowie]

Nope, I don't have a throttle body so I can't start the car.
