Hi All,

Looking for advice and input, please.
I believe I have a fuel pump going out and I'm not sure how to best diagnose the issue.
The port motor stopped running on the way back to the dock last Saturday. I was unable to get it going on the water and on the muffs in the driveway it won't run for very long before dying, if it fires up at all.
I believe I have a good spark.

How can I best test for good spark and good fuel pressure? My VRO is disabled.
I'm seeing VRO fuel pump rebuild kits for about $150 and new pumps for over $400.
I've never done anything to my fuel pumps, they are original as far as I know.
It looks like I have to remove the starter to get to the bracket holding the pump assembly?

Thanks for the help and input!

Jon

I think I have found a local Master Tech that rebuilds them for $150 and he tells me that I only need to remove the air silencer to get to the bracket holding the pump to the block. I'll check this out this weekend and probably take the pump to him next week for a refurb.

Well, I went to the expert yesterday afternoon with my bad vro fuel pump. He rebuilt it right in front of me. It turns out that the rubber bits in my pump were good (these are the bits that come in the rebuild kits that cost $150) and that one of the internal bits in the casing was bad. You should be able to pull a small vacuum with your mouth on a working pump and mine would not pull any vacuum. So, I made the right decision to go to him because if I had just ordered the rebuild kit I would not have fixed the problem!

Sometimes you're the bug and sometimes you're the windshield.....it's a windshield kind of day for me!
