I need step by step instruction on changing the alternator on a 1994 volvo 850

Go to you tube videos on volvo repairs by Robert, he's great!!

Very possible bad alternator. Have the alternator tested before you get stranded.

Fuel filter!! is it turbo?

Sounds like its in limp mode, where the transmission has a problem and to protect the vehicle it will not go faster. Check online for the parts you need, its mostly a solenoid that fails, unless you blew 3rd gear or something.

there is a bolt [or 2] that are hidden undernieth pump. other than that they come off easy

Step by step instructions can be found in a Haynes or Chilton's repair Manual. You can find these at your local auto parts store or possibly Walmart.

You'll need a torque wrecn and a degree tools (most auto parts stores sell them). Torque sequence is 15lbs, then 37lbs then 130 degrees.

Hmm, well that would really depend on which belt you got. I would start at the crank, go counter clock wise to the a/c pulley, up to the alternator, then to the idler, next power steering, and back to the crank under the tensioner, there was a longer belt introduced later, and IF you have that belt, same counter clockwise rotation, start at crank, go to a/c compressor, Idler pulley, alternator, power steering, then back to the crank, under the tensioner

The fuel-filther is located near the right back wheel andit is canistor and firsr DEPPRESSUREIZE the system
