Stalled at a light, wont start. pumping gas pedal with no fuel smell. Turns over, lots of spark. Changed fuel pump, but this did not remedy problem....what else could it be?

Could be the pump. Do you have the pressure at the fuel rail? If you have pressure and spark, then the noise you heard was probably lifter tap. No oil or over heated.

what is the make and model have you check the fuel pressure regulator

Check fuel line fuel pump

Make sure battery has a full charge. If it cranks good but won't start, check the basics. Have a helper crank it while you visually check for spark at the spark plugs, if spark everywhere, use a gage and check proper fuel pressure. I looked at info for the 3.8L engine, 35--40 psi. Also, after you build fuel pressure, turn off the key, see if fuel pressure holds for a bit? If the pressure drops like a rock, check for fuel pressure leak. Check the vac line for fuel pressure regulator, if it has gas in it, the regulator is faulty, or a leaking fuel injector. The pressure could also drain back through fuel pump.
Also, check fuel injector pulse, engine cranking. Any applicable trouble codes?
Smell of the crankcase oil dipstick, if it smells like gas, either you don't change oil and filter very often or the engine is running very rich for some reason.

the fual pump could be gone. you will smel gas but its not pumping it out of the tank

If the starter is turning fast you either have no fuel getting to the injectors or no spark to ignite the fuel. If you smell gas coming out of the tailpipe it's probably spark related. If you smell no gas coming out of the tailpipe it may be your fuel pump or a clogged fuel filter. Check the fuel pressure.

all a car needs to run are 3 things

Make sure it getting fuel in the engine

Make sure its getting spark

make sure its getting air

that's it it may be a simple not getting fuel check your fuel pump than check your coils or plugs.

Check fuel pressure. It sound like you have a bad fuel pump.

change the module

1. hold gas pedal to floor while trying to start. do not pump pedal.
2. holding pedal to floor is how you start a flooded f.i. engine
