Hello! I'm new to the brickboard, so take it easy on me. Here's my problem?

Engine is B200E, CIS fuel injection, TZ-28H electronic ignition, 108,000 MLS, Scotland UK. Starts on the coldest of mornings and will run to the end of the earth, but when I swith off the engine and leave it for an hour, I need much longer than normal cranking time before the engine will start. When it starts, it will run ruff, until i rev it, then it runs OK. Do I have a residual fuel pressure problem? The main fuel pump has started to make a noise for 5 seconds after start up, this make me suspect the accumulator is faulty?

Fuel pump relay has been re-soldered, and all electrics have been checked and are OK. Help!

Frank,

It sounds like the accumulator based on my experience. The local Volvo shop mechanic said there was never a problem before CA. went to oxygenated fuel. There is a test to be found in the Haynes and Bentley manuals. OH! Welcome Frank.You will like it here.

Hello Mark,

Thank you for your warm welcome. Oxygenated fuel? Do you mean unleaded fuel, UK.

I have almost the same scenario as Frank. on my US '89 200. It starts and runs fine , turn it off and restart it an hour later and it will run crappy then more then likely stall. If you keep the reves up a bit and drive it up to the firt traffic light, it will be fine.

Accumilator?? it that the black canistor under the intake manifold where the flame retarder hose goes to?? What am I looking for with that?

Welcome Frank.

Hello Tony, The accumulator is connected to the main fuel pump via a non return valve. It serves to deaden the noise of the main pump when the engine is switch on. After the engine has been switched off, the fuel accumulator maintains the pressure in the fuel system in order to facilitate re-starting, particularly when the engine is hot. I am hoping to change the accumulator in the next week and I will post a message to let you all know if it solves my problem.
