my car wont start i need help??? :/

[s13eater]

try starting it with the water temp sensor disconnected.

[s12-newbie]

funny you should say that! it started fine previously when the water temp sensor did'nt work & was'nt connected! now i've fixed it i'm having starting woes! whys that?

i'm going to do the self diagnostic on it 2moro

[s13eater]

water temp sensor makes it richer on cold start.

i'll give that a go! it was runnig quite good before the boost pip broke, then i fixed that & the temp sender, gave it a proper service of all service items & fluids & now have starting troubles, i gotta crack this & go for a spin with a full tank of fuel

i want to start fitting my new components intercooler/boost controller (new-one) 255ltr pump & a few other bits & give it a good velet inside & out!

dear me!

it seems to me that the choke/cold start is'nt working, what operates this & what do i do to correct it???????

where can i get a new temp sensor?????

i tried taking thetemp sensor off & its made no differance to starting the car?????????

[irish s12]

the choke on my car has never worked and i've never had any starting problems.you might have a vacuum leak.

i'm ill having starting troubles, i have a new temp sensor fitted (OE nissan part) i took the air regulator off & cleaned it & it did'nt help, when i removed it it was about 3mm open, it moves freely with a screwdriver, it says in the manual it can be tested off the car but i dont know how, i've heard it can be wired to work from a switch????? :/

i've changed my vac hose to the fuel regulator too as the old one was a bit hardend

i have some silicone vac hose in the post to replace othe vac lines but mine seem ok

its taking me 5minutes of cranking to get it going, then once warm it is'nt too bad, start fine once warm

i've fitted a new dizzy cap too

any ideas lads??? i need to sort it asap

[s12-newbie]

right chaps i've checked the temp sensor & i had a broken wire& the coldstartd problom is still there, i've checked the resistances & all seems ok, the air regulaters i have are showing 60.4 ohms & opens & closes off the car at differing temps!

is it an ecu problom, when i can get it to start it does'nt fast idle (cold start) it just sits at 500rpm & wavers up to 750rpm then back down again?

i've checked & double checked everythink i think, i've even ceaned up all my earths, the ecu has some dodgy wiring repairs so thats my next place to check but other than that i dont know what to do

i've also got two good temp sensors, & 2 air regulators, a spare FICD & i've cleaned them up, i have a feeling a wire orsome wire have possibly broken/chafed or the ecu is faulty

does the ecu come up on the self diagnose's if it has a fault????
