So bear with me here on my dumbness.. but on one hand you say if ECM does not see activity it will reduce power. But then you say the code (for no activity) will not reduce power.
Some of this might make sense.. as basically I am down on power. And from some reading I have read it derates power...
I can't find code 12.. code 44 is knock sensor? Says ECM is not detecting a knock sensor signal.. would this put the ECM in limp mode and retard timing?
Alldodge.. thanks for the help! I got codes 12 and 44.
Now with that said, I don't know how old those codes may be.. but regardless it might help. Do you know what those codes may be? I can't find that information on the internet..
And for what it's worth it about 3000rpms at this point.. it just won't pull more. Granted I have a tuber on the back.. but that's never been a problem. I've always been able to pull tubes with plenty of acceleration and power. Also replaced fuel/water filter.. no sign of water.. fuel "smelled"...
Yeah 5.0 Gi PEFS, 2000, about 500hrs. I also did new cap, rotor. Below is link to video I uploaded on how the injectors looked. Yes, while this test was taking place fuel pressure remained constant at 28-30 psi.
Ok throwing this back on top. Fix above didn't work.
I pulled plugs and they look "normal" to me.. all plugs have a good tan color. Did compression check and got 155-170 on all cylinders.. with each getting there in about 5 revolutions. Did fuel pressure check again, both at idle and under load...
Well I'm hoping I found the problem. I pulled the fuel/water filter to check for water or just analyze the fuel a little. Nothing notable there, but I noticed that the two lines that run from the high pressure pump side were very loose.. could easily turn by hand and could wiggle the line...
Good morning all! I've owned this Caravell for about 2.5 years. When I first got it, it would not go above 3500rpms.. diagnosed a ball fuel pump and replaced it. Granted it was not an OEM pump, but rather a knock-off. The boat has ran well up until now. It has about 450hrs on it and has been...
Hey everyone! New to the boating world but not necessarily to mechanical things. Just bought (what I thought was a clean, low hour) 2000 Caravelle with a Volvo 5.0 Gi. Took it out for the weekend. The engine starts and runs so smooth. Above 3000 rpms though it will eventually start to lose...
