Honda odyssey issue

What is your question?

Van started fine one day stopped it will start than die! it needed a tune up and several fixes all ready had timing done but come to find they didn't replace the crank. I put new plugs checked all the coils replaced battery and ground cabel that lost its bolts. The intake hose was dry rot replaced it. Replace egr and pcv and coolant temp sensor. I got it started one time drove around the block probably should have drove further but gass peddle still wasn't giving it correct power. I can hear fule tank power up but I never was able to get fule presher off the system to check presher. I'm thinking it's the regulator? The car starts and dies again now! Every time I mess with any evap system component it runs better and if I unplug the mapp it trys to fier. Scan tool on readiness reads, Ecu. 0# why? Egr. 0#Not ready -not ran enuf? Emissions. 0#notready- not ran enug? Fule system. 0# not ready- not enuf fule in tank

What makes this problem better or worse?

Every time I replace an item for emissions or unplug map it seams to help
