Cranks but don't start

2000 Ford Taurus cranks ohbut not start I have replaced the crankshaft position sensor the coil pack I'm at a loss as to which way I need to go from here. Also wanted to mention that since I put the coil pack in I have been able to start it but it wants to die right away

Fuel, spark, compression & spark at the right time. Check all those before throwing parts at it.

There is spark and there is fue to the engine but I haven't done a compression check not sure how

Do you have factory security or after market?

It has factory security

Got the car started it runs real ruff will not idle it just shakes and dies and smells like gas real bad

Just a guess. Fuel pressure regulator?
