I have no idea what a crankshaft sensor is. I'm pretty confident you'll figure it out by doing this diagnostic though.

You don't have one.

You really need to settle down, test one thing at a time, test it correctly and stop reading a bunch of stuff that has nothing to do with your engine.
If you are going to do voltage testing, then you need to learn how to use a voltmeter properly or your readings will be meaningless.

Your best bet right now is to get a test light like this or similar. Every place carries them.

Hook the clip to the battery negative terminal and touch the tip of the positive termanial and make sure it lights,
Then turn the key switch to run, and check the purple wire going to the coil to see if the test light lights up or not. If it does, you have power to the coil and ignition and eliminates a lot of problems.

PS, just disconnect the terminal off the coil and check the pin, do not poke holes in the wire,.

did all the tests, still nothing. when we started it for the first time it ran then tryed to run it again and just cuts off. is there anything else that i can check? is it possible that its the gas? had gas in there over the winter.

Which tests did you do?

Do you have spark from the coil when you crank the engine?

If you pump the throttle, does gas squirt into the carb from the accelerator pump?

i did the tests that you told me the relay is good the pump is good, when i pumped the throttle it did go in the carb. and the coil does have sparks.

Forgive my asking, but is this boat new to you? Ever run a carbed engine before?

I have a 2001 Volvo penta 5.7gs, I was wondering if the fuel pump ran continuously when started or if it stopped and started when pressurised, and if so is the pressure switch automatic in the pump or is there a float switch or something like that in the carb?

Calvowen87, you should start your own thread if you want help. Perhaps read up here to before you do
