2001 Evinrude 250 FFI run problems

[cmpulse170]

I've got 2001 Evinrude 250 HP FFI that was titled in 2006. The model # E250FCXSIG, serial # G04966565. I've ran the diagnostic software on Friday, 34 hrs of total run time and only have one code showing up and that's code 37 which is water in fuel code. The problem is while running the motor just shuts off like it run out of gas. The motor will crank but shuts off. The things I've done so far is: fresh gas, sta-bil,changed filters, checked all fuses, connections, new fuel hose, primer bulb and tried a seperate portable tank. The motor will not stay running after all doing all that.
I find it hard to believe the fuel lifter pump, fuel pump or the EMM is bad on a motor with only 34 hrs of run time although it's possible. Would it be possible that computer needs to be reset because it thinks there is water in the fuel? Any help or suggestions is greatly appreicated.

Several possibilities. Bad ignition switch, chaffed wires in remote control or bad PDP (Power Distribution Panel). If the engine starts and dies as soon as you release the key suspect the key switch! If it dies sometime after the key is released then suspect the PDP (when it dies look at the gages to see if you still have power to them. if not it most likely the PDP).

I tried to crank the motor again this afternoon, same thing motor cranks but dies as soon as I let go of the key. One other point, the motor will run about 1 minute longer with the high idle engaged. I don't if that makes a difference or not. Also forget to mention that I've checked the fuel pressure which is 20 PSI.

[Danrude]

When you say high idle are you speaking of advancing the throttle? Have you performed a compression check?

[cmpulse170]

I'm assuming the lever on top of the control box is the high idle. I haven't check the compression yet. Are you're thinking bad power head? I'm home today so I'll check it.

Just checked the compression it's 125 across all cylinders.

Just should always check compression to eliminate it. I am still thinking ignition switch first and possibly PDP. perhaps this will help. http://continuouswave.com/whal....html

I've taken the control box apart but can't find a part number for the key switch. I've also check all the fuses and connections on the PDP as well. Thanks for the help.

[Danrude]

Part # 0175974 Key switch. You have to have the repair manual and do voltage checks to confirm the PDP.

[cmpulse170]

Thanks!!! Will a multimeter work for testing? I've got the manual, that information will be in the Ficht fuel system section correct?

[Danrude]

A multimeter will do what you need to do! There is a detail electrical drawing of the PDP that tells you which wires come from the key switch, look for the violet wire which should have 12v with the key on.

[Danrude]

Look undr setion 4 of the repair manual and the next to last page in the book.

[cmpulse170]

According to the repair manual in section 4-116 the wire is red with a purple stripe for the key switch. The only way to get a reading with the key on was pull the plug from the PDP, which all the others work except the key switch. I'm hoping I did this right.

[Danrude]

I am having a bit of trouble tracing it in the circuit, It is the violet wire but it goes to the power relay first so check it at the relay, you will find on the port side of the EMM.

I got this message thru email but didn't show up in the post: Yes it is the red with purple stripe! If you do not get 12v with the key turned on at that connector then the key switch is bad. So I've got a bad key switch?

I changed that post. The purple red wire is the 12v from the PDP to the key switch verify it at the switch! the violet wire goes to the relay.

[cmpulse170]

Ok. The red/purple wire is showing no power to it on the connector end. So I'll need to verify power at the key switch and if it doesn't have power there as well that means a bad key switch?

AND??????? Inquiring minds wanna know.

[cmpulse170]

We've ruled out a bad ignition switch so either the PDP(Pwer Distribution Panel) or the EMM(Engine Management Module) is bad.
