R32 Gtr Not Starting Up

[YunisA]

Hi Guys,

For the last few days the car was running very rough with the exhaust gas light flickering, the car was almost misfiring. Now it wont start up at all. I am not sure how to put the car into diagnostic mode, if anyone would be so kind and advise how to do this?

Secondly, I cannot see the red led light up in the ecu, could the ecu be dead?

Many thanks.

the exhaust gas light could mean you.have a blocked cat. if its majorly blocked it can csuse the car not to start

The car does not have a cat, straight throught pipe..I think the problem is electrical

Google how to put into diagnostic mode. Or get a mate with a consult plug.

Theres a very good chance ur spark plugs are really fouled which will cause no start.

Check and replace the spark plugs then u can diagnose. It may just be a popped intercooler pipe, bad afm etc

Check your basic's, air/fuel/spark. Be good to check your plugs first as stated above. Make sure they arent fouled. If they are looking pretty good, id start looking into the fuel side of things. Maybe check fuel pressure and your cam sensor.

Hope that helps!

Do you have a vacuum leak?

Could have fouled your plugs so much so tht it wont start

[YunisA]

But why is the red led in the ecu not lighting up? Thats what makes me think its electrical or ecu related

[YunisA]

plugs checked not fouled and no vacuum leaks, have checked all hoses for splits...fuel pump is fine, there is also spark from the plugs

[DVS JEZ]

Plugs are fine- is there fuel on them after cranking or are they dry? Could be no fuel ie possible fuel pump failure etc.

Check there is sufficient flow and oressure in the fuel line. Make sure filter isnt blocked.

Check ALL fuses while ur at it

With ignition on does your engine light illuminate?, If not then sounds like your ECU has no power.

If all good remove CAS and spin it with your hands, re-check spark and put your hand over the injectors and see if you can feel them pulsing(clicking).

[YunisA]

Nope the engine light does not come on, and there is plenty of fuel in the car.

Id be checking all the power/earths to your ECU. Checking the ECM relay would be a good start.
