Any suggestions on where to find the fuel pump fuse on a 2002 Prostar 209? Indmar 330 HP 5.7L

I don't believe that MC uses fuses, none in my 2001 PS209. I have had trouble with the pump cutting out due to corroded wiring connectors. grab your test light and see if you have power at the connector to the pump below the rear ski locker. If you have power when the key is on then it is the pump itself. in that case seach the forums for fules pump replacements. there are many threads on this topic including how to fix them with parts from the local auto parts store.

yea unaware of a "fuse" for the fuel pump. Take a reading off the connections and see if its getting power before you trash the $$$ pump. Plenty of write ups on the cheaper alternative pumps also

The fuses would be part of the indmar package I believe not from MC. I believe the OP had a 5.7 in another post so I assume it was an LTR. Can one of you look near the ECM on yours and see If you have any fuses that look like the ones in this picture? I can't believe the fuel pump would not have any type fuse protection.

Take a look through this thread it has some different fuse locations also.

Can anyone tell me what the kill switch shuts down? Is it ignition or fuel or both?

Does your kill switch have a purple wires connected to it. If so based on the attached schematic on page second to the last page it would prevent the ignition and the fuel pump from operating as it interupts the positive from getting to the MEFI System Relay. When this relay is energized it supplyies positive to most of the ignition coil the ECM and the fuel pump.
I am assuming you have an LTR in your 209.

May want to PM EngineNut if this drawing doesn't match what you have. I am sure he can help.

I hope this helps.

Found the fuel pump fuse and it's ok. Kill switch is working. Any suggestions for what to look at next?

If you don't hear the fuel pump prime the rails when you first turn the key on.Then your pimp is bad.

Check for voltage at the fuse you found. According to the schematic I posted it your other post there is another fuse that controls the IGN/ECM. Make sure both have power to them on both sides. This fuse is what controls fuel pump relay. This is assuming from your original post that you do not have power at the pump.
