Excalibur 330 Fuel System Troubleshooting & Info

The $100 CodeMate is on www.skidim but it is for older ECM like Bruce’s 2006 with MEFI -4

You and I have newer eCMs that use DiaCom or TechMate. Rinda makes them both, the Diacom for around $700 and TechMate around $650. https://www.rinda.com/rindashop/

Update on the fuel pump issues: I received the LP fuel pump and installed it, also found and replaced the inline fuel filter. On the 2008 SN it’s located above the fuel tank.
I also purchase the TechMate code reader/tester from Rinda. I don’t have a convenient local repair shop so I’m happy to to have this tester now to see the Diagnostic codes on the ECM. I ran it on a hose for about an hour and the new LP fuel pump ran cool and the fuel pump relay only got warm. On the lake test the boat ran great and with the help of my ski partner, we were able to watch the fuel pressure gauge and it maintained 62 psi at wide open throttle. So all is good and with the fuel pressure gauge and the TechMate, I feel like I can better diagnose issues. The TechMate also has tests that allow you to shutdown spark or fuel injectors one cylinder at a time while under load(1500-2000 rpm). Nice feature. Thanks Bruce & Jay for sharing your experience on this forum!

That's great. I guess you have the PCM Diagnostic manual. If not, it seems like a 2008 might use one or the other.

The 4G Manual is on skidim as a free download https://skidim.com/gcp-4g-diagnostic-manual/

My 2007 diagnostic manual is below. Not sure why these are not linked in the Manuals Section of this website
