Engine problems from spain

[DOCDRS]

I'm assuming, among other things, this equipment reads an on board computer which actually monitors the sensors and retains the readings in memory. Think I'm on the right track here. If it's a sensor or wiring issue, couldn't one use a volt ohm meter to take the readings? A little more time consuming and more legwork required (looking up sensor specifications).

A cheap mans troubleshooting tool but it might help the guy out in Spain. I don't suspect anyone there would have this equipment and software. Even if he orders it, could take a while to get there.

a digital multimeter would do the trick, call indmar and speak to a tech there , they are very helpful and will probably send email you a wiring diagram maybe even sensor resistance values if they have them They are very helpful www.indmar.com

Thank you very "mucho"! We are looking for a mefi connector over here. There are loads of volvo and mercruiser official garages maybe they could help us. We wll also contact Indmar. The Spanish Moomba importer says that when he connected the software no problem came up. He also says that there is no "memory" as such, that he has to run the diag when the problem is happening. It doesn't make much sense to us...
What sensors could activate the limp mode?
Temp
Oil pressure
Tranny oil pressure
Water temp
???

Not all mechanics are up to snuff. Are they indmar certified? with a valid certificate? Call indmar and ask your questions. I would think water temp sensor and oil pressure would be 2 good ones . Which motor specifically do you have 340 cat? 325 mpfi? it always helps if you list it in your signature with boat model and year.

Just remembered. Look below to see if any of this might help. I had some electrical issues last year.

Look for the post by Engine Nut. There's a link to some schematics.

Thank you very much to all for your helps.

Within a month, starts the season in spain, heat returns and good weather.

And I want to have the boat managed to date.

I will return to Check all wiring and temperatures will look.

I'll get in touch with Indmar to watch the video.

I will talk about how to the problend end.

Thanks a lot.

While Indmar answers our email, we are checking the procedure to read the ECM ourselfs.

Here it says that the PCMs are equipped with Fault History, but it doesn't mention any Fault History for the GM Mefi5 Ecu.
Can that be right?

This is the problem....

I would look at the throttle position sensor. It's throwing a fault.

[santi]

stazi, where is the throttle position sensor? How do you change?
Somebody see something in the Parameter Description Value with faulted?.

Thanks DOCDRS.

[Arek]

Santi, hold on a minute.

Before we order a new TPS, you need to check the reading again.
Have you noticed this?

Fuel Pressure 147,9 PSI !!!!!!!!!!!!!!
The correct fuel pressure must be 60PSI !

Santi, espera un momento,
Antes de pedir un TPS nuevo, deberías volver a conectar el lector.
Has visto esto?

Presion de Combustible 147,9 PSI !!!!!!!!!!!!!
La presión correcta debe ser 60PSI
