hey i have a 92 s13 with a sr20 in it. i have been driving it now for about a year with no problems. i found a shell with no rust so i put my motor in the new shell witch is a 89. now i got all of it in and everything is working but the fuel pump wont prime. like it will crank but not turn over. i think it might have to do with the wiring cuz its a brand new walbro 255 pump. i think it might be the plug from the wiring harness to where the plug is under the dash. but not sure. i also suck with wirimg. if anybody can help ill be so thankful. im going to be away from a computer for a few days so if u could just call or text me that would be awesome (401) 486 3869. or u can email me at [email protected]. anyone would be great. please please help.

thanks

As long as your fuses/relays are good, it's all in your wiring. I had this issue when I swapped from a turbo silvia to a non-turbo silvia, I ended up having to swap ALL of my wiring...even behind the dash. Not sure how it is for a 240sx but I would swap EVERYTHING that you have...your issue is more than likely in the wiring somewhere.
