Blake,
If it has the 10pin Data Link Connector (like the one shown in the picture above), it should work.

Dave,

How about MEFI 4 systems. If it works, are the error codes the same?

Dave can you please PM me!

Frequency,
It will work on MEFI4 systems. The codes are the same for the most part, but MEFI4 systems can have multiple sub-codes under the same number that can differ depending on the engine (see example list below - from Volvo 8.1 ).

Kilroy,
You have a PM.

Do you know the pn for the connector you used?

Re: Make a Marine EFI code tool for less than $1.00
 

The connector is a Packard "Mertri-Pack" 150 series sealed 10 pin male connector. In addition to the connector body you will need the TPA (grey thing that clips to the top), terminals, seals, and (optional) plugs.

Dave,
I am having a hard time finding the DLC connector. I have found the transom harness connector (10pin) and the CAN connector.
Is it located near the distributor or ECM? this is on a 2003 mercruiser 5.7L vortec

Thanks,
Blake

Your engine has an ECM 555 controller. This trick will not work on PCM or ECM 555 systems. You will need a scan tool or smartcraft system display to read faults. :(

does this also mean I can't set the timing unless I have a scan tool?

Blake

Re: Make a Marine EFI code tool for less than $1.00
 

Blake,
You can't set the timing at all. Base timing is controlled by the computer and is not adjustable. You can loosen and turn the distributor, but it only aligns/misaligns the rotor with the distributor cap, it does not change the timing.
