fuel problem

[enyaw_13]

well i recently did a swap (E pistons in DE), and the fuel is going in, and there's spark and compression... BUT WILL NOT FIRE.

ok so from what I understand, fuel goes into the rail from the fuel pump and then goes back out from the other line.. correct?
well I'm not getting ANY fuel from the return line. how do we solve this? we tried putting compressed air through it to try to unclog it, but nothing.

any ideas people?

thanks.

Do you have the fuel lines mixed up ? * it does happen when ppl doing swaps, they forget*

Check fuel pressure, whats the readings ?

[enyaw_13]

nope. we checked and double checked that the fuel lines were flowing the right way...

we know that there is fuel going in and that spark plugs are sparking...
but it won't start up.


what else could it be?
