i just recently dropped a s13 sr blacktop in my vert but when i turn on the key to on my fuel pump dosent come on but if i jumper it at the fuel pump relay it comes on all of my harnesss looks correct power going to everything and im not getting spark to the coil packs ether if somebody has any experence with this problem plese tell me what u did to fix it

Killa_D · 01-19-2010, 12:32 AM

do you have a ignitor? Or it could also be you CAS sensor.

jza240sx · 01-19-2010, 01:08 AM

Check all your grounds. Also make sure your dash plug is in properly. It may not be giving up the proper power to turn on the fuel pump when you turn it into ACC. Thats what happend to me when i thought i had a dead fuel pump lol. Your coil packs maybe going bad or your CAS may also be going bad. Im having the same problem except I am getting spark and my fuel pump is turning on but i dont know why my injectors wont fire up....Good Luck to you tho

the cas is usually the culprit if your having both spark and fuel issues at the same time.

The only thing that is incorrect here is that your fuel pump should prime once upon turning the key regardless if your cas is bad or not.
If it turns out to be your cas I have a brand new one Im willing to sell for a good price.

memphis180sx · 01-24-2010, 05:53 PM

4x4le · 01-24-2010, 06:37 PM

have you tried another ecu yet

memphis180sx · 01-24-2010, 08:26 PM

im gunna do that the next time i get a chance thats what i was thinkn it was its a e5 ecu

4x4le · 01-24-2010, 10:11 PM

Ok, well your best matches on ecus will be the 62 or the e5. You can also use a 63 or e6 but those are for autos.
Dont go with a j4(5 speed) or j5(auto) because they are late model 180sx and they have a different pinout and you should have no trouble finding the other ones I listed for the same price.

I'm having the same problem....so far I've changed my. Fuel pump, egi relay, and I just got my pfc yesterday..all no joy...I'm gonna pull the pump and jumper it to make sure I didn't get a dud...but I'm stuck as well.

Check main engine ground, should be a yellow/black stripped thick wire.. should be connected from engine bay/ fire wall to the intake mani.. had the same problem.

I found my problem in the pigtail going into the fuel pump. Just called in a favor to a friend...to see if he can find me a fuel pump Assy. Good luck!
