well thats ma s12 sorted thanks for the help guys.
My dad figured out it was the fuel pump causing problems it was letting air into the system somewhere so we went to the scrappy and pulled a nissan almeras fuel pup moter out and he rigged it up so it runs in the old cradle
seem to be running fine now doesnt cut out or have rough idleing so that should be it fixed until i can afford a genuine part
.
At least it running so i can now (as of tommorow) Drive my new/old car
