Jimmae Viper

cheers but its a new battery and hasnt lost any charge

yeah lol. i thought it was something else (for some reason i was thinking about under the car)

ok when i say a bitch to cold start i mean not runnning temp (weather doesnt affect it)[it fires but then dies or is really sluggish until it gets going, it also stalls if i igve it too much gas before it warms to running temp]... i had a compression check done and its fine... Stock 25 ECU... ill look for the cold start valve in the morning as i gotta take off the body kit to get under... as for pin 43 i dont mess with the pins ect so have no idea about that... anyone know where i can get a diagramm for the engine as i lost mine from my computer (damn missus) Thanks for the massive amount of response, now who wants to help me do a cut and polish JV

basically im running a R32 with a RB25det (see my garage) it is being a bit of a b*tch to cold start the engine... i have a few posibilities from other peeps and just want a few opinions 1. Ignighter problem ($1200 for a replacement from nissan even with staff discount ) 2. Sparks(i may have got a bit enthusiastic tapping them to .8mm... will test this tomorrow ) 3. Fuel pump (unlikely as it runs fine and is aftermarket ) 4. Starter motor (as far as i can tell its working fine ) 5. timing/air-fuel mix any help on this matter would be much apprecaited and maybe rewarded with beer (not through post though)
