No spark or fuel pump

[norman2013]

Hey guys!
I purchased a 2002 deck boat off an auction site that has a 5.0 liter mercruser engine in it. They claimed it runs and drives. Motor looks very clean.
My issue. Motor will turn over just fine. It doesn’t appear to be getting any other power (no fuel pump noise, no spark etc.
what Iv done. I have bypassed the kill switch and I have replaced the 90 amp fuse at the starter. Any other suggestions would be much appreciated!

Is the engine efi? A model/serial number will help a lot

WAG based on provided info is the main power really if the engine is indeed efi

Kill switch maybe?

Be great to know what engine she is. If it’s not an mpi or mpi (would be one of the very first in 2002, if she was)…tou might not hear the fuel pump too well. If it’s an mpi, fuel pump will only be audible for a few seconds at the turn of the key to the first ignition position.
If it is an mpi or maybe an efi…if you turn the key and there is no fuel pump priming noise…but she turns over…it’s almost certainly inhibiting by means of the kill switch or in gear interlock.
Alternatively, if you do hear the fuel pump but only for a few seconds at a turn of the key. Then crank over and don’t get spark. It’s most likely your battery

Ok I can try to get engine info for you. Where is that located? Also is the kill switch bypassed by cutting the two wires and leaving them apart or splicing them together? I do not hear any sign of a fuel pump.

The kill switch and neutral safety switch circuit operates by closing a switch (when activated) and making a circuit to earth…usually.
The neutral switch is similar and won’t allow the engine to start when in gear. But this won’t be the issue, I’d think.
About the type of engine. If it has a carb, you won’t hear a fuel pump either at all…or until the engine is turning over, if you do.
An mpi usually says so on the cover on the top of it. Efi does too. On the flame arrestor. Certainly the mpi will give you a beep and a fuel pump buzz, at the first turn positioning of the key. The pump will stop after a couple of seconds. Have you heard similar from your engine previously perhaps ? But not now ? If there is no buzz (if she is an mpi)…it’s odds on to be kill switch related.

Ok on the cover it does say EFI. Digital Ignition. When I turn the key the gauges come on but no beep, no fuel pump, and no spark. This is a new to me boat bought on auction that claimed to be running. The engine and Bay Area look to be never touched as it is very clean.

Ok.sure sounds like it’s inhibited by a kill switch circuit. What’s the battery volts showing when it’s cranking over

 

[norman2013]

Ok guys I’m back at it today.
First thing I checked is battery voltage. I have 12.36 volts before cranking and it drops down to 10.2 volts while cranking. I have the kill switch wires disconnected. Can someone tell me if the wires need to be connected for it to run or disconnected. I know on a mercury outboard it’s disconnected so I’m going with that until I can find out. Iv also noticed I have one loose ground wire I don’t know where it goes. I haven’t found a spot for it yet. I will attach a picture. It doesn’t reach the solenoid

 

[norman2013]

Great news! I found a couple grounds that were discontinued near the solenoid area. Connected them to ground and connected my kill switch back up properly and I have ignition! Only other issue I see is when I hook up to water I have water coming out of the block in three locations. I can only assume that would be the block plugs and were removed for winterization? What do you guys think

 

[alldodge]

The kill switch needs to be connected. By disconnecting power is removed from the coil

12.36V is 70% charge, full charge is 12.6 to 12.7, could also be the meter accuracy

Yes, water coming out is probably plugs removed
