Hi all,
Not sure what happened with my other 2 threads but anyway, I've recently had a hard / no start condition with my throttle body injected VP. In the past year I replaced the fuel cell with both pumps, the alternator and the coil. New plugs and manifolds too and the boat was running well.
Then on occasion I didn't hear the 2 beeps and on Monday morning after running well all weekend it wouldn't stat at all. I went over all connections in the wiring harness and all seemed clean. After a while it sputtered to life and ran perfectly for 1.5 hours home.
I went down today and fired it up after poking around and then shut it off. Fired it up and no start. It would take 7 to 10 cranks then catch and run perfectly. If I shut it off then immediately it wouldn't start again. I replaced the fuel separator and it only had 20 hours and was free from water and contaminants.
I'm going to pull fuel pressure tomorrow morning and that's easy enough off the shrader valve. I'm assuming I can use my T in the line from the high pressure pump to the throttle body to pull that pressure. Any other suggestions let me know. I'm leaning towards the fuel cell, it doesn't seem to be priming as with before but I cant confirm. I do have my old fuel cell to try too.
Thanks!
