Need help diagnosing a fuel pressure problem



if you're getting uneven flow, the fuel distributor you were testing may be
clogged... or the injectors. the fact that the other 2 were spraying shows that
you are in fact getting pressure. even with low pressure, all 4 injectors should
follow eachother as far as spray amount.
