boost boy (starting issue)

[Sideways s12]

I got a question for you since your a veteran of the ca and seem to know your s***. I have a starting issue my car will crank but not start I have fuel because I cam smell it when I crank and I have spark checked each coil pack all have good spark. This has been a prob that's been steadily getting worse at first it wouldn't start so I pulled one of the coilpacks to check spark upon doin so the motor fired right up then it didn't do it for awhile. I recently changed back to the stock manifold after swapping the problem ocurred again did the same thing, checked for spark and the car fired right up.

Now I'm stuck (literally on the side of the road) with the same issue only this time it won't start at all cranks hard like it should but will not fire. Checked for fuel and spark and I got both. I unplugged the maf and she seemed like she wanted to fire up it start run for a few seconds then die out. I'm at my wits end with this motor right now. Any help would be greatly appreciated.

Ps I originally pm'ed you but it said your pms were disabled so I made this into a thread

Pps anyone else feel free to shoot ideas out here I need all the help I can get.

Check your timing. I am willing to bet its off, which is why you are getting fuel and spark but the car still won't start. Your CAS might be on the fritz if it comes and goes. Give it a turn and see if it doesn't fire up. I would highly suggest setting it correctly with a timing light if you have one though.

If that doesn't do the trick, its probably an intermittent grounding problem.

[Sideways s12]

I checked double checked and triple checked timing its good what's the intermittent ground issue and how do I troubleshoot it?

Alright, let's get your lump squared away . Always check the ecu for trouble codes as it can possibly narrow down the list of possible issues. If the ecu checks out code 55, we can look into one obvious area "Grounding". This puppy needs to be grounded and grounded well. Make sure your battery is up to the task as well. The water temperature sensor will cause the car not to crank as well. It is notorious for flooding the motor when it either fails or have an open circuit to a possible bad connector. Go through some of these and let us know what you come up with.

Ok so check the ecu for codes. Is it the procedure the same as the single cam ca's because those have diag on them too and I know how to check those...also battery shoukld be up to the task its brand new well only about a year old anyway. How can I tell if the wts is bad? Other than it throwing a code? I will check all that you stated and get back to you tomorrow thanks for the help.

[Sideways s12]

Ok sorry its been a few days but I been busy trying to find work and dealing with classes. Anyway I checked the ecu for codes and there is a lot of them. These are what I got...

11
22
33
44
55
The only I know is 55 which boost boy said what are the rest or where can I find them....I had the starting issue again today something is causing the motor to flood. And that's why it won't start. I unplugged my fuel pump and cranked it a bit, then plugged it back in and she fired right up...so what could cause the flooding? Fuel pump is stock btw.

[Sideways s12]

Bump anyone have any idea or can you atleast point me in the right direction of the codes? Don't bother saying look in the fsm as I don't have one.

From reading-the-fault-codes-on-your-ca18det ... 70584.html:

The codes are: Possible cause: Symptoms:
11 Crank angle sensor circuit Wiring fault(connector), faulty sensor. No or difficult starts, bad idle.
12 Mass Air flow meter circuit Wiring fault etc., sensor, ECU No or difficult start, lack of power.
13 Engine temperature sensor circuit Wiring fault etc., sensor, ECU Engine stalls, lack of power, low economy
14 Vehicle speed sensor circuit Wiring fault etc., sensor, ECU Lack of power, poor idle
21 Ignition signal missing in primary coil Wiring fault etc., sensor, ECU No or difficult start, bad idle, misfires
31 E.C.U. (E.C.C.S. control unit faulty) Wiring fault, ECU internals ?
33* Exhaust gas O2 sensor circuit Wiring fault etc., sensor, ECU lack of power, low economy
35* Exhaust gas temperature circuit Wiring fault etc., sensor, Cat/conv lack of power, low economy, dash lamp
43 Throttle position sensor circuit Wiring fault etc., sensor, ECU lack of power, low economy, stalling
45 Injector leak ? Wiring fault etc., sensor, ECU ?
55 No malfunction ( all normal )

But I'd think it should be there in the FSM as well.

11, 22, 33, 44, 55... not wanting to sound stupid, but isn't this just the ECU cycling through the 5 diagnostic modes, waiting for you to select one? I haven't ever read out CEL codes, is the diag mode # flashed on both LEDs, or just one?

[Sideways s12]

Good question because not all the codes are listed in the list you just posted if that's the case how do I check the codes lol I know on the single cam ca you just turn it to diag mode and it gives you the codes.

It's detailed in the thread linked above, but basically, after the "33" flashes, turn the dial back to the base position. It should be in Diag Mode #3. This is where it should flash the CEL codes. Red light for tens, green for ones.

[Sideways s12]

Thank you sir!

[Sideways s12]

Ok well I had time to do some stuff checked the codes and all I get is 55 no malfunction. I get this real bad smoking now under boost from the engine bay like the manifold is being sprayed with oil or something but only under boost if I stay out of boost it doesn't happen checked turbo and it appears to be ok

[boost_boy]

Believe it or not man, your turbo is in a bit of trouble. Check the return line to make sure it isn't kinked. I mean the oil has to drain smoothly back to the pan which means no 45 degree bends and hair-pin turns. Sounds like the classic signs of a turbo in distress to me, but let's hope I'm wrong on this one. Btw, what turbo are you using and how many miles are on it?

[Sideways s12]

Its a the stock t25 and I'm not sure how many miles are on it because its not my original I got it from a buddy. But the drain is not kinked I thought the same thing so I changed the hose completely because I thought it was leaking at one point. But there is no kink I have a feeling the oil feed may be messed up its my only conclusion even tho its new iono lol

With regards to the overfuelling, when you turn your key to ignitioon (not cranking the engine), you should hear your fuelpump, does it keep pumping or does it stop after a few seconds?
A friend of mine had similar overfuelling issues, wich turned out to be a faulty ECU, this also caused the fuelpump to keep pumping after turning the ignition on.

Put that turbo to sleep . It's old and tired and only going to piss you off as time goes on.

The fuel pump is good I ruled that out a few days ago and yea it turns off after a few seconds like it should thanks for the input tho.

Trust me I am but I can't do it right now as its my only running car I have a freshly rebuilt 60 trim waiting to go on along with cam gears and 1000cc injectors for e85 along with tuning mods as well but I need to get one of the other s12's up to use as a daily in order for my beast to be down.
