2005 XC90 5 cylinder stalled while driving.

Was out shopping, stop at a store was in store for 20 minutes. When came out, car started and drove for 2 minutes and car started stalling. The car wouldn't restart, left me and my family stranded. Got a tow home, had a friend put a computer on it. And got error for crankshaft sensor. Replaced crankshaft sensor, no start just cranking. I replaced the electronic fuel module, still no start. Took it to a shop they told me I was only getting 75 PSI compression,need around 150 psi. Was told to get a new engine. Could this be a fuel problem? My top two cams where in the right position. I don't feel like the engine would just die all of a sudden. Please help???

How many miles on it ? I understand the timing belt looks good ? Could it have jumped a few teeth ? Maybe undo the left cover to have a look at the tensioner and water pump. 75 psi compression is really low - if they measured it correctly, that would meant the valves hit the pistons. When you crank does it make a noise like a vacuum cleaner, spinning fast like this ? www.youtube.com/watch?v=3J3qYNmcy3k

120000 miles. No vacuum sound just cranking sound

Could it be a fuel issue?????

Try measuring the fuel pressure with a gauge, it should read around 60 psi . May also try to ask on the S60 forum, for a 2.5T engine . You have the AWD (which can have problems with the DEM) and there was also a recall for water leak through the CEM harness under the windshield cowl, but otherwise it's pretty much same issues as the S60

Check your cats to make sure they are not clogged. Restrictive cats/exhaust will cause some of your problems.
