well, first things first you said no fuel is coming out when you try to start the car with the fpr removed. That being said i do'nt think the problem is with getting spark.
You just replaced the fuel pump. Have you checked the circuit to see if there is a fuse blown or if something is unhooked to the fuel pump? It sounds like your fuel pump isn't getting any power.

so when you have the ftp unhooked and you turn the car on fuel continiously comes out? My pressure reads high 40's when the car is on without the engine running so that means fuel should be coming out pretty good with the fuel line open.

I'm going to take a wild guess and say that the power to the fuel pump isn't the only electrical problem you have which is why i suggested finding out that issue instead of just bypassing it.

This could be a long shot but can the sensor in the key lose the signal and stop the engine from starting?...i replaced my ecu on my mazda at one time, it would attempt to start but wouldnt turn over but then i reflashed the key and it turned on...maybe it could be something else but just throwing it out there

you would think but i changed a tranny out in one of my boys cars and didn't tighten the bolt up enough and it rattle loose and the sensor came out a little. enough that car would not start and still never threw a code. although i know it was still there it just wasn't making contact which should of threw a code. but no fire sounds like cps to me. if you have someone local have them come over and just swap there out real quick and try and see. that way it cost nothing.
