2003 utopia205 240efi electrical help!!

[Lakia1]

Ok back ground
Motor hydro lock last year in July. Insurance finally came through. Here's what was replaced.
power head
Fuel pump
Fuel water separator filter
Fuel rail
Reed assembly
Injectors
Water pump
Spark plugs
Starter
Alternator

Mechanic got everything together. Motor started. Constant beep with oil light. Ran motor. Mechanic said it was low oil sensor, plenty of oil and oil was being sent properly. After first hour of break in at only idle, moved up to plane. Ran for half hour then lost power unless idling. Idled back to boat trailer, loaded and turned off. Tried to restart and it turns over but nothing. I feel it went into limp mode because I ran it with the beep without replacing sensor. Mechanic thought it wouldn't bother anything if I did. Bought the new sensor for the oil and gave to mechanic after I dropped three boat to him. Still won't start.
I've looked up different things on here.
I'm having the mechanic check the triggering. Fuel water filter. The black/yellow wire from the tether. He will be looking at those tomorrow. Not sure if I have the guardian still installed or not.
What else could be causing an issue? Any help is greatly appreciated!!!

Or is it a crank sensor? Signed up to be a premium member and looking at manuals. Looked like trigger was prior 2001?

Look in the manual for a constant beep with oil light on - it should say what that means. If it was the low oil sensor in the small tank it would be only 2 beeps that’s it. Not constant. Find that out.

Engine break in procedure states don’t let it idle more than 10 minutes. You want to vary speed every couple minutes to a new speed.

 

[Lakia1]

I was varying speeds once in plane but nothing over a certain rpm. Just was following the instructions of the power head I got it from.

I've looked in the manual and there are multiple things for constant beep.
Throttle sensor, manifold pressure, oil pressure
But nothing with a constant beep and oil light. Hence why I am here asking as well. Maybe two separate items.
It started and ran. Seemed to go into limp mode then when turned off, it would not start again

On my 240efi (gen 1) in my Challenger 2K.... the constant beep at key-on is when the fuel is VERY low. Disconnect the pink wire connector coming off fuel tank (fuel sender wire) and the beep goes away.

Something maybe to check. I ran my boat out-of-gas the first outing... d'oh!

Cheers!

 

[Lakia1]

I will have him check it. I know the boat is full and was taken to mechanic with 38 gallons in it.
Manual says constant beep can
Map sensor
Mat sensor
Tps sensor

Looking at your list of replaced parts-
Water pump??? What water pump?

Seems like some parts were replaced that should not have needed to be replaced.

 

[Lakia1]

It was a water pump kit that came with the power head. Don't have any idea lol. Fuel rail, injectors, Reed assembly, starter, and alternator we replaced because they had damage from the rod that came out the motor.
Fuel pump, plugs etc were just because it was recommended.

I know you know a lot about these boats. Any help? It's greatly appreciated. It started and ran. Now it's not. Guidance to the constant beep? Thank you

Start with checking for spark x6. While the spark plugs are out, run a compression test. All plugs out. WOT. NOT in the water. What is your battery voltage while cranking? I believe you have a different ignition timing system than my 2001 engine. I think you have a crank position sensor. There should be a way to test it in the book. Have you visually checked that the throttle plate(s) are open a bit while cranking? Is your throttle working properly from the helm? Have you ever had ignition timing set?

 

[Lakia1]

Battery is brand new.
I agree on the crank sensor vs trigger. After reading more I saw that.
I will check all the things you are staying. Don't know if he checked timing when putting it all back together.

 

[Lakia1]

So mechanic couldn't get to it. So I brought it home.
It starts now.
I am still getting constant beep when key is turned on and reduced power.

Tps and map sensors ordered as that's what I read on the manual the constant beep would be with reduced power. I also ordered a crank sensor just because it eliminates another sensor.

Oil light is on, new sensor installed. Could it be the magnet on the float in the tank on the motor?

This is a 2003.

Brand new battery means nothing. What is the voltage of the battery while cranking?

 

[Lakia1]

Gotcha. I'll be testing this morning? I will have that answer shortly lol

 

[Lakia1]

10.5 v on start
Positive and negative hooked to alternator but only getting 12v at battery at idle.
Shouldn't I get 14vish? Also the two write plug is not plugged into the bottom of alternator, does it have to be?

 

[Lakia1]

On the alternator, should it have 3 or 2 wires plugging into the bottom?

 

[Lakia1]

Here is the only plug I have by alternator. Three oil sensor is attached to the other wires. It should be a two wire plug. So I'm confused now

 

[Lakia1]

alright mechanic hooked up regulator and TPS sensor reversed. So the constant beep is gone. Now I have oil light with 4 beeps. But no start. So now I'm looking into that. This is fun hahaha

 

[Lakia1]

Update:
Starts randomly but acts like it's starving for fuel. Tried running it on the water and out starts to do a solid beep with no power except idle.
Tps, map, and crank sensor replaced.
Wiring proper, after finding regulator wires hooked improperly.
Still have oil light on and 4 beeps every 2-3 minutes
Drained gas out of fuel/water filter
Added sea foam in case there's water
Getting spark
Oil sensor replaceD

Did you check the float in the oil reservoir? Sometimes the magnet comes apart from the float causing the beeps. Happened to me after I replaced the sensor thinking it was the issue.

Another way to rule out the magnet/float as the problem would be to bypass the sensor all together. If the beeps stop, you can assume it's the float.

 

[Lakia1]

I do not believe mine has a float. It has the sensor but no other wires.

 

[Ozweego]

The float is sealed in the white semi clear oil reservoir on your motor. You can't see it unless you drain and take the reservoir off.

The new sensor you installed actually threads through the float and magnet from the outside in. So even with a new sensor, if the magnet isn't riding the float it isn't getting picked up by the oil sensor.

As I mentioned, this may not even be your problem. The easiest way to check without having to take it apart is to cut both blue wires off your old sensor. Leave the plug ends on them. Then connect the two raw cut ends together with electrical tape. Now you have a wire with two plugs that isn't connected to anything, which is what you need. Plug that bypass wire where the new sensor was plugged in.

You have now created a bypass. Start you motor up and see what happens. If the beeps return you can rule out an oil issue. If the beeps go away you need a new oil reservoir tank.

Hope this helps.

A few more pics from the manual that may help

 

[Lakia1]

I have continuity in the oil sensor. I have also connected a wire between the two connectors to eliminate the oil sensor.
In just running it yesterday after trying to get sea foam through it, it now has a solid beep after about 5-10 min of idling. This was in the water and on hose. I feel it starves for fuel as it starts only half the time now as well.
