sr runs and then wont start !! help!!

[juanm203]

so i recently got my sr swap on my 90 hatch, and it was running till i got to the gas station to pump some gas and when i tried starting it, it didnt start . so me and my friend pushed started it and it started right up. i thought it was the fuel pump because i had the stock ka pump so i got the walbro 255. the next day i tried starting it and it started up again after i took it around the block and got back home it didnt start again so i took off my starter and went to get it rebuilt,, after i got it back i took it home put the starter back on and took the car out for a test drive it was driving perfect untill it started bogging / jerking and it shut down on me completly i tried starting it but will only crank and then i tried push starting it but it wont even start that way !! can any one help :/
