How to troubleshoot a fuel issue
We have a 1989 Ford F 150 that's sat for a yr & then was
given to us. We can got it to turn over a few times by
spraying starter fluid directly in to the intake but it won't
stay running. Help! What should we try from here? Before
having to guess which fuel pump (there's 3) it might be.
Check for fuel pressure at the test port. If you have zero try to jump fuel pump relay and listen for fuel pumps. If you have pressure check for injector pulse.
