We were out 3 days ago and after 6 or 7 swap outs the boat would not start, and stil hasn't.

2001 Mastercraft X-9 with 330 HP LTR Engine. Have Fuel, Kill switch is working. Batteries are good.

Engine turns over but never catches.

Thoughts on what to check next?

Thanks in advance.

Do you have fuel pressure ... could be a fuel pump failure ... check the pressure on the fuel rail

I am new to this boat. How do I check the fuel pressure at the rail?

Hold on I will find a few pictures ... what you are lookign for is where the fuel pump takes its high pressure line to the engine, on the fuel rail there is a valve (looks like the valve on a bike tire) ... take the cap off the valve, if you depress the needle gas will come out of the valve (so hold a towel over it) ... let me look around for some pictures and I will post in about 5 minutes ... also, if you do a "search" look at the terms "fuel pump" and you will find that your symptoms have been experienced by many of us

Try this thread and see if it helps:

this is not what your boats fuel rail looks like (exactly) but you should have a good start ... also, look at the thread above for info on how to test your fuel pump pressure (if you dont want to do it the backyard way - depress needle on schrader valve)

Thanks, the pictures really help. I will go try that.

The boat is in Neutral.

The gauges turn on when I turn the key.

If it's crankin' but not starting you're not getting 1) fuel or 2) spark (I know...I'm a GENIUS:rolleyes: )

A fuel problem is more likely, and it seems that I've heard about fuel problems in the past from others.

Thanks everyone for the prompt responses. From reading your responses ans searching for fuel pump failures, I think I have enough info to go back to the boat at start troubleshooting the Fuel Pump. If that does not appear to be the problem I will update my thread.

I just got back from the boat and the fuel pump does not make a sound when I first turn the key, nor is their fuel coming out of the scharder valve, so i think it is probably the fuel pump.

From reading other posts it sound like I should be able to change it myself.

Any advice?

Your challenge will be disconnecting the fuel lines, which requires a special tool. If you have one (or access to one) of those, then actually changing out the fuel pump isn't that tough.
You'll find plenty of threads here by people who have had to do it.

Dumb non-mechanic question here...

Are the fuel pumps circuit-protected with a fuse or circuit-breaker?

Everything electrical is protected. The fuses are on the motor and are labeled.

you should be able to change it yourself ... but you need some special tools for the quick disconnect and you don't want to over-tighten the bolts that hold the the pump into the tank ... the other thing I did was confirm that there was not a problem with getting elecricity to the fuel pump (using a multi-tester on the wiring harness) ... also, I did not use a torque wrench, but I did pay attention to how tight the bolts were to take off - you don't want to srip them out when you put the new pump in ... when you put the new pump in, act like you are putting a wheel on your car (snug them up, then tighten them in in a crisscrossing pattern - i.e. don't just follow around in a clockwise or counterclockwise manner) ...

I got a new fuel pump from my local dealer, and stopped at Kragen Auto Parts to get the Fuel Line disconnect Tool. Once back at that the boat it took about twenty minutes to swap it out.

When I turned the key to the right I heard the sweet sound of the fuel pump priming the lines. It started on the first try.

We spent the next 4 hours wakeboarding and tubing.

Thanks for everyone's help, I would not have had the confidence to do it myself without the tips and photos.
