How to read fault codes??

[Ryan]

Hey guys, just put my engine back together and won't start, Check Engine light is also on. How do I go about pulling fault codes from the ECU? Cheers

I've found the two black wires and connected them, but the CEL just keeps steadily flashing? No error code flashes etc..

[Ryan]

At least I think it's the right connectors, they're right above the brake pedal. Althought the wires are black with red stripes. I can't see any green reset wires

i think it should flash code 55 for system normal... i doubt this will tell you why your car wont start tho.... have you checked basics??? does it wind over? fuel? spark? my bet is you have put fuel lines back on the wrong way around...

[Ryan]

Winds over sweet, fuel definately coming from pump, and can smell fuel after cranking for awhile. Unsure of spark??

pull the fuel line off and check if there is fuel actually going into the rails not dead heading into the regulator. also pull a coil and plug out and check... have you plugged all sensors back in? crank angle and cam angle? temp? have you heard it fire at all?

[Ryan]

Found a unplugged connector by the boost solenoid pack but can't find anywhere for it to plug in?! Picture attached..

[Guest boostcut]

airflow meter dude....

[Ryan]

Theres a pipe on top of the regulator that broke off when I was dismantling the engine lol, possibly a problem?! Can't find where it would connect to tho..

[Ryan]

Na got the air flow meter connected, it has a slightly bigger connector. Theres a big empty space there because I've got the AFM sitting right on top of the turbo (due to having no 90 degreen silicon bend after upgrading to VF22 turbo!)

[Guest boostcut]

it should still run without the afm tho.... that pipe is the vacuum for the pressure reg... it was in the pipework under the manifold that you have taken off.... just run it to a tee on the manifold..

[Guest boostcut]

is the tps and idle control valve plugged in?

[Ryan]

Ahh found the vacumn pipe..going to hook up now. Yep TPS and ICV plugged in.

[Guest boostcut]

how many pins are in the plug thats not connected.

[Ryan]

4 pins/wires. Want a photo?

Does it matter that the two bottom hoses off my boost solenoid aren't connected? Keeping in mind that I just want the engine to start at this stage, obviously the wastegate hose will need to be connected in the long run!

[Guest]

Look behind waste gate solenoid bracket

Is there an ignition module there?

[Ryan]

Legend! The side facing the engine bay was plugged in, but other side of the module wasn't So that solves my loose connector, but the CEL light is still on and still won't fire/start.

Go through the basics

Diag check, OK ?

Fuel - is the fuel line from the filter going to the top fitting on the fuel rails

- is the pump running for about 2 sec when key first turned on?

- do you have fuel inthe tank? (sorry silly Question)

Spark - remove 1 coil and place an old sprk plug in the end of it , place the end of the plug to earth and try to start - any spark?

One easy mistake also is #2 injector plug and cam sensor plug can be fitted around the wrong way - check this

( will log faults of 13 and 15 )

[Ryan]

Fuel is hooked up correctly, and when I take pipe off by regulator it comes out sweet. Pump runs for 2 seconds when ignition turns on. 1/4 of a tank of fuel. Just tested a coil and got spark sweet..

Whats the diag check?

[Guest]

If you have been trying to start with that ignitionmodule plug disconnected, your spark plugs will be foulded

Remove them all and check before you go too much further

[Ryan]

Ok will do. But I still have the problem of the CEL light I need to solve before anything else aye?

[Guest boostcut]

your cel wont go out until the engine has started???? i could be wrong but id be focusing on getting the btich going
