Engine died while running, now won't even crank

[fireman_bob]

Hi,
I have a 2000 200HP E200FPXSSH that has been running fine all year.
I was out today running between fishing spots and, with no warning, the engine hesitated slightly then died. No CEL, no horn, no other warning lights. Engine won't even crank. When I turn the key on, I get the test lights and horn, but that's it.
I checked the fuses and they are all good. Battery appears to be good as dash voltmeter shows about 12v (was running fine all day stopping and starting at various spots).
I had the EMM rebuilt last year due to a failure (engine died, CEL came on, engine would crank but not start).
Any ideas on where to start?
Thank you,
Bob

Are you saying it won't turn over or anything? If this is the case, double check all fuses, check your safety kill switches and neutral switches. If none of these will allow your engine to turn over then your next option is to take to your local dealer for further diagnostic.

Yes. That's the case. Further testing showed all the proper voltages at the PDP pins with the key on. Fuses and relay's are all good. Have power to the EMM. No communication over the serial link.

Thanks for your help.

Unfortunately I do not believe that the computer will interupt the starter relay/solenoid. I recommend checking the start solenoid, maybe by p***ing to see if engine will start. Also check your wire harness.

According to my wiring diagram it sure does. The EMM controls the ground to the fuel pump relay (brown wire to PDP/EMM) and the ground/coil to the start delay relay (brown & gray wires to EMM), neither of which are working in my case. How familiar are you with this particular engine?

Unfortunately not very and unfortunately I do not hove access to the service manual. If you are certain that the computer is not allowing the motor to start, your best option is to take to a local dealer.

I've pulled the EMM and sent it to DFI Technologies in Alabama. They will be able to verify if it's bad and repair it if it is.
Thanks.

I was just going to suggest that. I hear good things about them. I had an EMM go last year and took it to the dealer..... a grand later the motor runs great but I believe DFI is quite a bit cheaper. If I have problems in the future I will definately send it to them. Keep us posted.

So the EMM was found to be bad by DFI and they repaired it. I've installed it and the tngine runs, but won't go above 3500 rpm and feels "rough". I need to set the timing. Can anyone please explain the procedure using the EVDiagnostic software?
When I go into the ignition timing section of the software and hit the set timing button, the engine always stalls. I can restart it, but the software is now disconnected.
Thanks.

Unfortunately the computers have to be programmed by an authorized dealer. The require the dealer program and the software to be downloaded from the Dealer website.
