hey all i know there is about a billion threads already on this but ive read em all and followed all the suggestions but i still cant get my car to start.

when i first instal it all and tryed starting it up it run but i turned off cuz lots of smoke coming outa bonnet (new heat wrap). car started again after this, the idel was all over the place and hunting bad.

turned the car of and went in for eats.

the injector duty is only at 1.1 when it starts cranking then goes done the long you crank it...

some1 plz help me

turn the car to ON but dont start it

look in ETC, SENSOR SW CHECK

do you see any sensor names highlighted in black ?

if so what are they ?

have u checked and spliced the map sensors?

where did you phsyicall install the map sensors?

[Adriano]

I would say its gone into clear flood mode, if you keep cranking, it cuts the fuel? Have you got the two sensors hooked up and plumbed properly. What injectors are you running? Are the AFM settings set to d-jetro?

[wolfwood]

um map sensors in cylinder 3 and 4, 555cc injectors. nothing highlighted

dont know how to put areflow meters to djetro

Mate i think you should have a good read of pauls FAQ's before something gets damaged

Are the map sensors hooked up after the throttles(right near the head)

hmm okayyyy

[STATUS]

i bet you have fouled the plugs.... did you set the injector correction for the 550cc's?

[wolfwood]

i did set it for the diffrent injectors but didnt do that the first time i tryed to start the car.

so i guess i should go get some new plugs and see wat happens?

[wolfwood]

just checked the plugs, there a bit black but apart from that seem to be fine, any other ideas

[wolfwood]

another question with a sard fpr is the side line feed or return? cuz when i took the side line of and primed it that pissed out with fuel, maybe the lines are around the wrong way?

[Beer Baron]

side is in, bottom is return.

[wolfwood]

no i mean side, there is a bottom side and i little line from top

[wolfwood]

well sorta found out the problem, set the shit up for diffrent injectors and changed plugs and went fine.

drove it and when put foot on the gas it splutted a bit and died, wont start again same as when plugs were f**ked.

least i know its something to do with the fuel. will jsut have to save and get it tuned

Ben's asked me to ask a few questions, Suggested to ben to buy some new plugs,, fixed the starting problem..

im having trouble finding the lag time for Nismo 555cc.. i think its 0.73 but i need correct numbers.. or is it 0.71 anyhow.. the car is not registering more than 10% or so inj duty.. im thinking that because its map based sensors and not Maf based .. there is no base map for this version of the power fc.. which would mean its not sure how to " GO" because its not been programed to covert the map signals into something useabble.. is this correct??

realistically does it need a tune before it should be test drivable.. or should the engine be capable of atleast moving up and down the driveway without flunking out..

the car wont start again.. im assuming we have roasted the plugs again. too much fuel could the Sard fuel pressure reg be up too high?? any help would be greatly appreciated..

Thanks Guys

there are 3 hoses. the top one is vacuum/boost. the one on the side is fuel in (from rail), the bottom one is fuel out (return to tank).

and yes you need to check the pressure of the fuel reg. it should be 3 bar base pressure (no vac or boost).

[Adriano]

Set the inj trim to .80, and set the fuel pressure to standard, or put the standard FPR back on, how much power are you expecting? The stock FPR is good for 350rwkw, so are the injectors. Should start up, run and be drivable from the word go

[wolfwood]

hmm dont have the stock fpr anymore, poop. i had the trip set to 80.

guess i will have to try and find stock fpr

cheers ben

[Adriano]

or set the pressure to the factory specs, i think about 42 psi with the vacuum hose off

[wolfwood]

so when i set it i take the vacuum hose off?

[Adriano]

Can be set with it on or off, just need to set it to a different value. I prefer to set with it off, dont even need the engine running, just power up the fuel pump and set.
