willing to bet you got a bad fuel pump or you still have the stock fuel pumpif you run a couple tests you should be able to find outfirst check for spark hook a spark tester up make sure you have good sparknext hook up a fuel pressure gaugeif you have good spark and fuel check the compressioni know ive seen cars with ess are's swaped in them with the stock fuel pump and its a turbo motor with bigger injectors it needs more fuel then the stock 240sx pump can handle

I'm not an sr guy but I would start with fuel and ignition, you gotta have the right amount of fuel and enough spark to light it up, I would check all ignition components

i went to a little audio store. and a guy has a s14. he said that ka has the same size injectors as the sr. but i dont know. ill check plugs, then get a walbro 255..

[Zippy69]

Ka injectors are 270ccsr injectors 370cc

YES . ME TOO

I SWITCH TO BOSCH PLATINUM 4

I would think it was the fuel also. Running an SR with the stock US fuel pump isn't a good thing. A local kid kept reaching destination because of that. The walbro pumps are really cheap for what you get, easy to put in too.

+1

+1 on the fuel pump......I had the same problem, you NEED the fuel pump to be able to floor the gas safely.
