Volvo: 1990 volvo 740 gl cranks but won`t start, volvo 740 gl, fuel pump relay

Question
I have a volvo 740 gl. recently i started having problems getting it to start.after i would drive it for awhile and turn it off it would take 15min to 30mins to get it to start again.now it refuses to start at all.it just continues to crank. i have already replaced spark plugs,cap,rotor and plug wires.what else could it possibly be?i was told it could be my timing belt.please help i need my car back!!!!!!!

Answer
Candi,
Some testing will be required. Pull back the timing cover and see if the timing belt is ok. You can get an idea if the belt is broken by removing the oil cap and cranking the engine to see if the camshaft turns. Also if you have a Bosch system and the fuel pump under the car just behind the drivers seat feel it while you crank the engine and see if it runs. If it does not run check for power going to the pump. Things like the fuse and fuel pump relay.
