    ""I am nearly 100% sure the fuel pump primes, I definitely hear noises.""

    Just because you hear it prime isn't all you need to do. You will need to check the fuel pressure. You can usually rent a fuel pressure test kit at most auto parts places. You should find a shrader valve under the intake front right side on you engine. Its circle in red.

    You should have pressure in the range of +/-35 psi at key on and then when cranking.

    I am nearly 100% sure the fuel pump primes, I definitely hear noises. I have not tried to jump the kill switch wires but I can. I just noticed that the breaker to my Gages is busted, so I will have to go get another one. That should be bypassed though as the wire to the engine doesn't go through that breaker. I don't have fake a lake anyways so will have to wait to take it to the lake. I can't tell if the crank sensors have been swapped so will try that once I get to the lake.

    I know you said you checked the lanyard but did you bypass it to be sure that's not the problem. Sometimes the clip is attached but the pin is not depressed far enough. Disconnect the wires on the switch and jumper them together. That will rule out the kill switch.

    Does the fuel pump prime for 2 seconds when you turn the key to ''On'' ?

    Tons of information in the Winterization section on here. It's very easy to do and requires very basic tools to complete. It will take you a third of the time on your second go around.

    I was nervous too on my first time a couple of years ago but everything turned out fine, and I'm confident that with you using the info on this forum you will not miss anything either.

    I found 15 amp fuses in a plug above the ecm, are these the correct ones? All are okay, and I checked the 2 sensors to make sure they're plugged in. Are these the crank position sensors? I did find 3 relays as well, any way to check those?

    Took some pics on my phone, gotta figure out how to attach them.

    Just a bit of advice. You seem like a decent DIY guy, and it's pretty ironic that you got your boat winterized by someone else and now it's not working.

    Do it yourself this fall, its really easy!!!

    They are going to basically be right under the coils packs on the front crank pulley. If they are bad, you won't get spark and it shouldn't fire injectors either as it won't be able to properly phase everything. Make sure both plugs are plugged in. On the off chance they disconnected them they could have put them back in backwards. If they did this the motor won't run. Oddly enough on mine the longer plug goes to the nearest sensor. So it is easy to reverse them or bend a pin if you disconnected them.

    Front of the engine, they read the reluctor ring immediately behind the harmonic balancer aka crank pulley.

    The metal cover over the ecm doesn't have any fuses, but I will poke around there after work today and try and find some fuses. Thanks for the help

    At key on you should hear the pump prime for 10 seconds. If not check the 3 fuses below. There are 3 mounted on the same cover as the ECM at least on mine. To check the fuse you have to remove it from the holder. If the fuses are good and you hear the pump prime check for fuel pressure. If its good have someone crank the engine while you wiggle the connectors on the crank position sensors. Mine had bad connections and just tweaked the female connectors to make better connections and she started right up. Hope this helps.
