ok so i got my motor in wiring harness tranny i replaced the ptu, im not getting fuel in the motor tomarrow im gona test all the ohm injectors, what i hear is they should be between 10-14 ohms, i tryed hooking one of my old injectors to the injector clip to see if it was working and it wasent. when i run the ecu for codes i get #55, but i have a check engine light on, on the dash, when i did the swap i used the jdm wiring harness and found the altanator wiring harness to be differnt, i think i fixed it and i dont think that has anything to do with fuel, also the ptu is of the na motor, i dont think they are differnt, when doing the motor swap i also installed a walbro 255 the fuel line infront of the car has pressure tho.


so i dont know whats wrong and need some help, any help would be greatly apresheated

 

after installing the ptu i got spark so i sure its good but maybe not?


and the motor will run on starter fluid?

 

you really should have bought a new wiring harness. what ecu are you running?

check your injectors, FPR, fuel dampener, fuel filter

 

im thinking harness like B. you should check to see if the injectors are getting signal to squirt when you turn it to start. i assume you can do this the same way as on the S30's and just use an LED put into the click turn the car over and see if it flashes. some one correct me if it doenst work like this though like on the S30's but from what i remember on my Z32 same style clip and one is signal one is ground, so i dont see why not.

 

im using the jdm ecu

 

i hooked my na up tho and got code 55 also?

 

is there a way to check the fpr or do i just replace it?

 

yes there is, you get a fuel pressue guage

you did this swap and dont know how to check your FPR ???
and you should check to see if your injectors are getting signal. or pull your plugs and see if tehy are wet/color change soemthing... if not that means you got no fuel! its easier than checkin your fuel pressure.

 

from what I can see it's your fuel issue. Make sure you didn't hook up your fuel lines backwards that is a very common mistake. if that doesn't fix / help. go to radio shack and buy an LED put it on the connectors and crank the motor, if the LED's don't fire up it's your Harness/ ECU that is bad. after you have done that repost and let us know your progress. then I will further assist you. I have done several N/A to TT swaps.

 

ok so injectors where all about 12 ohms, all injector clips made the led light up after some cleaning..

dose all the intake piping have to be hooked up for it to idle??? so the maf can read proprely?

 

im going to test the fpr right now and ill post the fuel pressure thats in the line

 

all the piping from the MAF back needs to be there, you have made sure that your fuel lines are on the right sides right?

 

yea i checked the lines
but ill check agian

 

what lines should i hook up the fuel pressure gauge to and what pressure should it be at?

 

check the basic stuff. Are you gettin fuel past the fuel filter? thats the only way in for fuel.. .easy test. pull it off after fuel filter turn key on for half a second see if some comes out... check the basics first.

 

thats also a place to put the fuel pressure gauge

 

tested the injectors and the injector clips then installed new fpr and dampner injector clips needed to be cleaned also..
so i installed new fpr and dampner started up thanks for the help

 

glad to head you finally got her done. i am kinda suprprized teh FPR went bad Z32 FPR are legendary and can handle anything you throw at them. non the less congreats =]

 

good to hear.

ill be up at torch lake/traverse city in july. maybe ill see you driving around sometime.

 

ok well im having more problems its still not running right i put in a after market fpr and ran fine but had way to much pressure in the line 125psi. dont think it should be anywhere to that.
but just found out i put the fpr where the dampener goes if i put it where the fpr should be like this
http://zhome.com/ZCMnL/PICS/hesitati...104-181014.jpg

will it work and be adjustable? when it was where the dampener goes, i got it to 70psi in the line with the aftermarket fpr. might be hooked up back wards?


also dose anyone know where to find a vaccume diagram??? might have some leaks also??

 

o sweet well i will be all done in july i hope.....
