Crossed jumper cables car won't start

SOURCE: 1993 volvo 850,cranks but no start,no codes,

You should Replace both the Fuel Pump and the Fuel Filter for this Low Preassure Issue and the No Start Issue Both.

SOURCE: My 1995 Volvo 850 will not start. I think it is

another way to test it
unplug any fuel line you can locate tell a friend to start key one turn only if the line squirts fuel then pump is working and it might need regulator
if not then pump is gone

Testimonial: "That was good. Since I necer hear the pump I am shure that when I open up a line I will have proven out the bad pump. Thank You."

Make sure you have a fully charged battery...clean the terminals real well.
Alternator only charges the battery when the correct engine rpm is attained.
A clicking noise could be the starter solenoid which is basically a relay / contactor but can block power from reaching the starter.
Worn brushes in the starter can also zap a battery's power.

Battery, starter and aloternator can be tested at most part stores.

From what you describe, I'd clean battery terminals and ensure battery is fully charged.
If clicking still happens, I'd move to the solenoid and starter.

Hope this helps...

you will need to try to turn the engine manually to make sure its not frooze. if it turns then you might need to check the starter again.

SOURCE: 89'volvo, car starts rough but after running for 5-8 min it stalls out and won't restart. i have replaced the internal fuel pump and fuel pump filter. could it be a fuel relay switch or other?

when car dies check for spark if you have no spark check the igniter and coil as well as spark plugs cap and rotor
