1994 -850 Turbo volvo has hesitation in starting then pulsates as if it wants to shut off. While driving it wont go faster than 10mph. I changed the spark plugs, wires and distributor cap. Took off fuel filter to check for blockage. Car still acts likes it starving for fuel or air. Does anyone have an idea of what the next step would be for troubleshooting?

if this is the right front mount just behind the r/f wheel that would be ok, if this is the top mount on the engine below the windsheild go to IPD Volvo site and get the mount and do it yourself (easy)

Check the fuse to the injector. If it is out or got wet, it could mimic these conditions. let me know what happens. I have an 85 model.

The problem wont be your timing belt. you need to take out a spark plug plug it into your HT lead and check for a strong spark or even if there is a spark. check your contact breakers on the distributor as well

SOURCE: car is stalling and idleing irradically.

I Would Suggest That You Complete A Engine Cylinder Leak Down Test.....(not A Compression Test But A Leak Down Test) this will tell you if you have internal problems....possible worn rings or a burnt valve(s) I would use a smoke machine to check for vacuum leaks also. Good Luck

If your air mass meter tests good, the I would tell you to check the HIGH PRESSURE PUMP underneath the Driver's side chassis pump holder-next to the fuel filter.

There are 2 pumps on your Volvo---the in-tank low pressure, and the chassis mounted high pressure. The car will run with the in-tank failed and the high pressure good. It will not run with the high pressure failed. Test the pump by applying voltage to the two terminals.

Another common failure, should the high pressure pump be good, is the HALL EFFECT SENSOR located in the distributor on the back of the engine. Once this sensor goes, it's no start. A rebuilt or used distributor may be the answer to your problem.
