Hi Mario .

This looks like a typical security issue due to the system not being able to read the chip ignition key .

First i suggest you try a second /spare key .if still stalling then you will need a good scan tool to check for malfunction codes .

Other possible malfunctions that will cause your engine to stall a few seconds or less after start up .

MAF sensor.

Crank shaft sensor.

Cam sensor .


To know you will need a scan tool as said above .

Put key into ignition switch to ON and check that the security light is out ,if still on or flashing then you have a security malfunction and the keys will need reprogramming .

Need further assistance with this issue then please get back to me with the reply box below .
After rating there is no further cost for any other question relating this issue .
Kind regards Greg

I have tried all your advices and checked them all and still the engine won't run and just this morning I finally decided to remove the injector 1 out from the cylinder and I installed back the lines to the injector outside of the cylinder and installed the electronic system and I started engine and I found out there is no fuel coming out from the injector and what do you think, is the ECU is not working?

Hi .

You need to check at the fuel pump if you are getting power to the fuel pump when you switch on the ignition .

When ignition is on the power to the pump will only be 2 seconds so you should have battery power at the pump for two seconds then crank the engine over you should then have again battery power at the fuel pump .

If you do have power replace the bad fuel pump .

If you don't have power check the fuel pump relay could be faulty .

Did you check for any malfunction codes .

Good morning I have replaced already the fuel suction valve and also the crankshaft sensor and I have grind all the intake and exhaust valve and after installing the engine start and run quickly but after few seconds the engine stop again and what I did is removed the fuel line from the tank going to the fuel filter once I switch on the engine the fuel goes out for few seconds maybe 3 seconds and I have also observed that this is also the duration the engine will stop from ramming and what comes to my mind is that the engine stop because there's no more enough fuel to the system as why only run for maybe 3 seconds and am I correct so what do ypu think is it normal that the fuel supply will really stop for 3 seconds only? I hope again you can help me solving this and I'm glad if you can give me your utmost hehehehehehe and perfect opinion for this because I know we are already near to the solution and once my engine will go running I have to bring this to computer analyser so that everything g will be done. God bless

Good morning Greg, I had checked the Fuel pump and also the the relay and I took out the the hose going to the fuel pump just to ensure that after 2 seconds and I continue to start the engine and I found out that the fuel continue to deliver and make sure there is a power to the pump I also put a check light on it and it's working and I even replaced the camshaft sensor but still the engine will stop for few seconds perhaps I have no more recourse to tow the car into the service center and it's about a hundred kilometers from my place and what worried me is the road has lots of hilly mountain to go hehehehehe I hope I can fix the engine already. God bless

Today I started the engine and the engine run for about 10 minutes and it went off again and I observed while the engine run the light of check engine is on and when it's gone the engine stop for few seconds after the light went off hehehehe I am surprised why because supposedly the engine will run smoothly while the light is off and in my case it's reverse thing happened.

Hi Mario .

Try Ebay for a ECM you will find them a lot cheaper than getting one new from the dealer .OR if you have time have it sent to the UK and have your ECM repaired .this way there will be no need in having it reprogrammed and save a lot of cash .

Please click here

God Bless and all the best Greg

Expert:  indy-tech replied 17 days ago.

If you have the time you will save a lot of money as a repair can only cost $50 - $200 .

and no charge for programming the ECM as yours is already set up for your car as all new ECM must be programmed ti work in your car .
