Rb25det Not Starting On First Few Turn's.. Help?

[nismad]

Hi, I have an RB25DET in a 180sx and it used to start on first or second turn, the car then sat around for about 6 months and ive only recently got around to finishing off the project, now it dosnt start for 5-6 turns and really struggles to get going, once she's going shes fine.. smells a bit rich though, so far ive cleaned the AFM, changed spark plugs and fuel pump, has anyone had this before and if so what was the cause.. any ideas?

oh and i think it might be fuel related or caused by lack of fuel as i found the plug going to the fuel pump was damaged and obviously tryed to start it several times with no luck.. would this of caused a blown gasket or somthing??.. guess ill have to check compression.. help?

thanks,

Gareth

what computer are you using? Some after market ones cause the engine to crank over a number of times before starting...

[nismad]

just the standard ecu man..

[nuclear_skyline]

All my knowledge went out the door!

[nismad]

wish it was programed into the ecu to do it man.. wouldnt have to fix it then

[blind_elk]

Have you had the injectors cleaned recently?

[nismad]

nope.. would an additive be worth trying or should i bite the bullet and get em cleaned?

[nismad]

I'm going to get a fuel pressure guage to see if that could indicate the problem, has anyone experienced a problem like this before?

any help would be sweet.. dont really wanna pay someone if i can fix the problem my self

A battery lying around 4 6 months may be quite considerably drained

and wouldn't be charged up as effectively by the alternator

[nuclear_skyline]

replace your fuel filter... if its clogged it wouldnt be helping.

Again, thanks heaps for the input guys..

*Nismad goes out to try some the above suggestions...

Just going though the service manual and was wondering what is ment by the term Start Time Enrichment not fuctioning??? is that when the fuel pump primes?

+1 for charging the battery

NEW BATTERY.

My mates GT-R sat in my shed for about 6 months and his battery wouldnt hold charge and struggled to start.

My battery died and it struggled to start, then after it started it would make the sound like when you turn the key while its runnin, the horrible grinding sound. Got a new battery and went perfect, started first go, no horrid noises.
