Check the tube from the air cleaner to the turbo, plus the intake on the air cleaner. It really sounds like something got sucked into the turbo. Best not run the car until you check it out! If there is a lot of smoke, your turbo is shot! Some can be rebuilt though! The high pitched sound could be your alternator. After you have checked the other things, remove the belt to the alternator, start the car, if the noise is still there, then let us know. OK Frankster016

On the far right warning light--SRS--is what is showing--never seen it before--'91 740 turbo station wagon--thank you for your time--louise


This light is refering to the Safety Restraint Sysytem. This includes such items as seat belts, airbags, modules, etc.. This needs to be serviced by a trusted technician who is versed in SRS systems as they can be dangerous when not serviced properly. Is there anything else not working like the horn?

Not starting after replacing fuel filter and tune-up


I had the same problem with a 1989 Volvo 740 GLE station wagon. I did the same thing you did. But this time I talked to the local Independent Volvo service shop, not the dealer. The problem turn out to a bad fuel pump in the gas tank. You can replace it from inside the back of the station wagon. Just remove the floor panel to access the top of the fuel tank. But before you do; note that there are two fuel pumps, one inline underneath the car on the drivers side, and the one inside the gas tank. Before, you replace any of the fuel pumps check the fuel pump relay behind the astray on the left side. It could also be a bad relay.

It is a right hand thread and you usually need an impact gun. Take the fan out of the way, to give you more room, I have found that helps.
