No change at all on the motor. Still hard to start and not full power.

I do not know what was the trouble... might be the pump!?


One does not normally have to buy new injectors. A lot of companies will test non electrical ones for free & then one gets exchange ones or has them reconditioned. Generally it is the burst pressure that is the issue. IE the point at which the fuel gets injected & the pressure at which they inject that affects performance.  Timing also has an effect because they have to inject at the correct phase of the cycle.
Compression on a diesel is  higher than a petrol engine so valves etc are often a source of problems. A compression test is worth doing before spending money on expensive repairs.
Re the starting it is worth checking the glow plugs by checking the voltage.
I had a problem & was just a simple glow plug relay at fault - cost less than £15-00

Very good point Samuel and it could also be a glow plug but any good mechanic would have checked these items first anyway one would hope.

Glow plugs were the first suspect to be eliminated. They have full voltage, correct resistance and the relay is OK. I wish it was that simple.

I suspect it is the injection pump but it is not a bad idea for the injectors to be rebuilt. Future reliability is my main concern as I am often far far away from a place to get things fixed. I have good mechanical abilities, and spares on board such as belts hoses and filters along with the tools to fix them. However I wouldn't be able to deal with a major breakdown.

In a pinch I could probably use the dinghy as a tug, but the outboard is only 2 HP so we wouldn't get anywhere fast:)

In Florida years ago on a Pearson 424 we had the Perkins diesel seize because the spin on oil filter was cross threaded and blew off, pumping all the oil into the bilge. The alarm went off but I didn't hear it until the motor stopped! Engine alarms are rarely loud enough. Anyway, my son and I managed to sail it into a marina, and tie up. There was a boatyard there and they did the repair job. Expensive. Full engine rebuild, but then we knew what we had.

Fingers crossed that this is not so expensive.

Good luck

i had a similar problem a few years ago, it was tracked down as you rightly concluded air was getting in..
it was my fault. I rang my mate who used to service my engine a Volvo MD2010C and asked for his help..
he listened and patiently went through all the could be’s and got me to right them down, starting the simplest reason, as he knew I had done some work in the fuel system.
The first thing was to go along he fuel pip and check every pair of jubilee clips and make sure they were working opposite each other. I had two pairs that were not working ( screwing up within 10degrees of each other) together.. this cause a pinch in the hose and allows small amounts of air intermittently into the system..
So my first thing as my mate said “ always start at the beginning”.
This worked and I have never ver made this mistake again.

I ran across this thread on ybw.com which seems to indicate it could be the exhaust elbow. Worth a check. On previous boats with Yanmar diesels it was a regular replacement item every few years. I'm not sure if the one on my Volvo has been checked, but I will bring it to the mechanic's attention.

At my MD2040 from 2003 i replaced all 3 glow plugs last year. The engine does also not start.
You can measure the resistance of the glow plug. If the resistance is infinite, the glow plug is blown.

I did not use the original Volvo glow plugs (358025) because to expensive (46€ each).

I used
febi bilstein 24917 glow plug, M10 x 1,25 / M4 x 0,7, for 9€. but it fit also other models.

The mechanic phoned me yesterday to say that he had reassembled the engine and it was ready to go. The injection pump was fine, but the injectors were rebuilt. One of them was basically open all the time. In addition two of the three glow plugs were burned out and had to be replaced. Used ones were used as new ones were not available locally.

Anyway, it sat overnight and I went down to the boat this morning. It started on the first touch, I could hardly get my finger off the starter fast enough! Ran clean and smooth. 

I'm pretty sure we burned out the glow plugs when trying to start it before they took out the injectors for service.

Have been out sailing, and the engine started and ran fine. The final bill was about 3200 CDN. A bit more than I expected, but then every boat expense seems that waySmile

This included diagnosis,  rebuilding injection pump and injectors, replacing two glow plugs and taxes.
