Thanks for your help guys,
I replaced the battery with a new one but the problem is still there, now i Noticed something today, usually when i turn the ignition key halfway, the fuel pump makes a low zzzz sound for a second or 2 which is normal, that means its pumping gas to the engine. But i noticed that whenever this problem happens the fuel pump doesn't kick in or make any sound anymore.
Second thing is that the problem shows whenever the car is warm, on a cold start yesterday morning, i left the car turned on for about 45 mins-1:00 hr until it turned off then it took about 35-40 mins of cool down for it to turn back on only for a few mins then turn off, (keep in mind its not overheating)
then tonight (It was a colder night) & on a cold start at night, it took 2 hrs 10 mins for it to shut off, so i guess it is affected by temperature.
I've also heard that faulty relays might fail under high temperature, so i tried switching relays with others but nothing did the trick, I removed the fuel pump relay & starter relay & switched them with rear defroster relay & AC clutch relay They're both identical & same rating) but nothing solved the problem
Tomorrow morning I'm taking the car back to the stealership, hope this time they'd be able to diagnose the problem,
Any thoughts/help is very much appreciated as I would share your ideas with the mechanics working on the car.
Thanks,
TY
