I'll try to make this as straight forward as i possibly can....

i installed a ported and polished intake manifold, upper and lower, a BNR stage 3 turbo, a knife-edged TB with the TB mod done, etc etc and my car WILL NOT start for the life of it....

at first after all the mods it would start, then die right after, try again and it would do the same, again and again it would not hold an idle above 300rpm, so i check and the MAF connection is unplugged and my car is smoking, ****, ok so i plug it back in, and it starts and idles for 10secs, i'm shocked and astounded so i figure i just need to tune the idle, so i try to rear in the engine bay to revv. it a little to keep it going.... nothing....

it dies and since they hasnt even made a blip at wanting to start, at all....

i re-checked the vac. line's, made sure they were all correct, but nothing is getting this thing to start....

any idea where i should start guys?, i know last night when i had the sec. fuel rail off it was a constant dribble out of the fue line of gas to the point it covered my foor with litre's of gas without stopping, could this have something to do with it?...

anyone!?..

 

Jumper the fuel connector.

Are you runing a stage 3 on stock computer? Are the stage 3's still runing the drasticly undersized hot side?

 

jumper the fuel connector?...

yes i'm running the stage 3 on the stock computer with a PFC FCON as a piggy back....

i just dont understand why it's not starting now....

 

are you getting fuel??
if not...

Engine fuse bliew?

Brake booster hose off the back of the throttle body.

Hose off b/t the bac and intake duct.

Something caught b/t the intake manifolds causing a large leak.

God only knows. It's a case of looking for spark and fuel then.......

 

the car has spark, and it has fuel, you can smell the flooded-ness....

brake booster hose is on the TB

BAC and intake duct?, ok this is a possibility considering i dont recall where/when one was on there....

nothing between the intake manifolds, both are flush and tightened....

 

so i just got back from the garage, tried adjusting/checking the TPS but i cant get a reading properly, at all, so if anyone has a wicked write up they want to shoot my way, by all means it would help!...

so i checked the MAF, connections, everything, and it WONT start but it's getting fuel AND spark, so i have no idea whats wrong, does anyone have a better vac. line diagram i could use although the one i have is amazing, or anyone have any idea's why the hell this thing wont start?, i have no idea, and i'm stumped....

 

If you have fuel and spark and its not starting then you have, No compression or flooded motor.

 

i would guess it's a flooded motor

 

+1
yank the EGI and floor it and crank (in sessions) unitll the mist stop pouring out of the plug holes

 

out of the plug hole's?...

i'm supposed to have it floored when i pull the EGI fuse!?..

and yes, i believe it's flooded, SEVERELY....

 

if it's just flooded, Disable the ignition & fuel pump, do what 88rxn/a said, leave the spark plugs out over night to allow maximum fuel evaporation, refit spark plugs ,reconect fuel pump &ignition & try it... worked for me

 

Or don't worry about taking the plugs out, pull the two EGI fuses and crank it over until it tries to start. There'll be a short window where the mix will be right and it'll catch or even start, but then die almost immediately. THEN put the fuses back in and it should start right up.

That way you won't have to worry about taking plugs out or waiting overnight. :P

 

Could you explain to us how it is going to try and start without spark?

 

If it is flooded too badly you wont be able to build compression even if you cut fuel and spark to clean the motor out or let the fuel evap out over night, you still have the problem of no oil film to build compression.

Some oil needs to be injected into the lower plug holes of each rotor to build compression. A good 2 cycle oil it best, others have used ATF or regular oil in a pinch.

Or.. if you don't like that link... See my sig.

 

i'm currious though, what are the two EGI fuses?, i know i pull the 30A one and crank it over for 7secs x3time's and it hasnt helped, and i'm dead certain it's retardedly flooded, put it this way, it's flooded to the point it smoke's white smoke out the exhaust, YES it's gas though....

but, 2 EGI fuses, details?...

how can i disable the fuel pump, i assume this is the EGI fuse?...

is push-starting the vehicle an option?...

 

Read my link... or search.. There is ONE EGI fuse...

 

Hmm. . . Because you didn't take the plugs out, and just killed power to the injectors and the fuel pump? Just going out on a limb!

Both of the top two fusible links in mine (a 30 and a 40) said EGI, one was EGI something and the other was EGI Inj. I was never sure which was the right one so I've always pulled them both.

If your car is retarded flooded though, like you can smell raw gas when you pull the oil dipstick, then you're just going to have to change the oil.

 

^ I was pretty sure the EGI fuse disabled spark as well.............. am I wrong?

 

Not on mine, but my car had enough odd attempts at electrical reengineering that it's possible that's not the way it was originally designed. Mine maintains spark though with both fuses out, it is a stock computer, too.

 

i smell the car being flooded and it come's out the exhaust, this i'm certain....

regardless if there's a ton of gas in my oil, i'm changing it as soon as i get the car up and running anyways....

any other tips or hints you guys may have?...

 

Like they said before though, if there's enough gas in the oil, it'll be hard to get enough compression to start it, I know that for a fact.

 

so plainly, pour some 2cyl. oil into the plug hole's and crank the bitch over?...

how much oil should i put in?...

 

I always just pulled my main EGI fuse and cranked it for a few seconds in several cycles, then plugged it back in and it would fire and run just fine. If that dont work, try pissing on the spark plugs while cranking it. Thats a good way to get the plugs un-fouled.
