Style chooser

i have a question to ask. why whenever i try to drive a large injector of low impedence (peak & hold type) via a resistor pack to a vehicle wid existing high impedence injector system i get this trouble of getting the car to idle on the 1st start. i have to wind down the fuel pressure till very low around 1.8bar in order to get started. starting up wid a low duty cycle couldnt help much wid stock fuel press as it seems doesnt response ... and once it ticks, i foul the plugs.

why ah..? can...
