[FONT="]Hi all - I have a 2000 5.7l EFI Mercruiser that will crank strong but won’t start. I took the flame arrestor off and noticed that the injectors aren’t shooting any fuel into the throttle body. I do hear the fuel pump when I turn the key to on/run.

[FONT="]Boat has run well all summer, and was running great this weekend. After a few rounds of skiing, picked a spot to anchor down, but then it never wanted to start after that. Was really hot in my area so thought maybe I was a vapor-lock victim. Sat there with the engine compartment open for an hour and still no luck. Checked today, still no luck. Just cranking - no fuel spraying into throttle body.

[FONT="]Things I’ve done so far:
[/FONT]
[FONT="]- verified the safety switch is set to run
[/FONT]
[FONT="]- visually checked connections.
[/FONT]
[FONT="]- new plugs, wires, distributor cap, rotor, ignition coil in summer ‘19.
[/FONT]
[FONT="]- didn’t check for spark simply because there’s no fuel spraying so didn’t think spark is my issue.
[/FONT]
[FONT="]- haven’t checked that I’m getting fuel pressure to the injectors yet. Read that the EFI systems require a special Schrader valve to do this??
[/FONT]
[FONT="]
[/FONT]
[FONT="]Any suggestions? Crappy weather the next few days so might be Friday before I get back out to keep moving on this.
