Question about 2000 Saturn Ls 4dr Sedan
I changed coil and ignition module, check for fuel and pressure and everything was ok. I also changed crankshaft sensor but car cranks but won't start.
disconnect you battery. take something and fray back the plastic on the main hot wire on the coil. take another wire and wrapp it to the main wire you just frayed. now take that wire and run it to you ignition fuse. re connect you battery and see if your vehicle will start. if so than you have either a break or a short in you hot wire for your coil.

I noticed you replace the crankshaft sensor, but not the CAMshaft sensor.
The Ignition module takes the input of both sensors to tell the coil when to energize.
This sensor should come up as an error code when you attach a obd reader.
Even if your light is not on - there may be a code. If it is not your vehicle originally, some people pull the bulb!

The check engine light should be on--rent a scanner, read out the codes, and pursue to repairs. The one sensor you didn't mention is the camshaft sensor. It is a hall effect device and depends on a magnet passing to generate triggers. It is combined with the crankshaft sensor and they work in tandem with the CPU to generate firing. Maybe the magnet came off of the camshaft? If you have access to an oscilloscope, you could look for pulses from both sensors where they go into the ignition module--terminal 'G' for the crank, and terminal 'K' for the cam signal.

Testimonial: "tHANKS FOR ALL YOUR HELP ALL THIS CHECKED OK FOUND IT TO BE BAD FULL INJECTOR ...."
the first thing to do is scan the computer for codes,also when the module was installed did you clean the mounting area good? the next thing i would look at would be the crank sensor, also theres a reprogram on these cars,the dealer needs to install or update a computer progranm on some of these, you would have to call with the vin #, this doesnt affect your nostart condition, its just something you should have done,
