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

[s12-newbie]

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
