VOLVO PENTA TAMD71A COLD START and ACCERALATİON PROBLEM

[Celik28]

I own a volvo penta tamd71a. I have two problems. Firstly, when the engine does not run for 3-5 days in winter cold, the first starter also works with difficulty. After pressing and releasing the starter, the engine turns and misfires many times. At that moment or in the same day, when I stop and start again, it starts instantly. The second problem is that when I do full throttle from idle, there is a slight acceleration of 2000rpm, but then it stalls, even though the engine is at full throttle, it suddenly goes up to 2500 after 3-5 seconds. That is, it eats gas by itself. I talked to two different authorized services. They said it's the same. I think it's usually the same problem with volvos. I wonder if any of you had a similar problem?

I would start by looking for an air leak in your fuel supply. If possible change any rubber hoses and clips/crimped joints. Older crimped hose connections go hard and can let air in but don't leak fuel out.

As far as I know, I know someone with this problem. First I will check the advance setting. Then I will pour the fuel directly into the pump with serum.

Sure sounds like bad fuel or restriction to me. Check your filters and their contents for water or anything that shouldn’t be there.

I don't think it's water, I change the filters regularly

That won’t stop it most times. Or bad fuel

As the engine once it is running is basically ok the timing advance is almost certainly OK. I really wouldnt try and pour fuel straight into the pump - too many things to go wrong. Rubber fuel pipe and clips are really cheap. Change them all, check the filters for diesel bug and water and see what happens then.

I will proceed in order.

I would get some fresh diesel in a jerry can..take the hose off the primary filter outlet and dip it into the jerry can...Will rule out plenty ! good luck.

I am checking the advance setting at 20 degrees. That is, at the factory setting. As a second option, I will look for air in the fuel line.
