iv had issues lately with starting my car in the morning n iv taken it to some places n they have tested everything and say everything is fine. i no its not the ptu. but once iv started it the car runs fine all day untill in the morning when i come to start it. some1 said it might be the cold start injector or valve. plz help and advice will do.
well what exactly does it do in the morning? is it hesitant when you drive? perhaps its the coolant temp sensor (located at very front of engine). have you checked error codes?
the car dosnt crank over it will only start if i put the pedal down at a certain point after a while. my mechanic said he thought it was the temp sensor because it was giving the wrong reading n the temp sensor was wrong it was red but he called someone n they said its ment to b black but he got one but it didnt fix the problem. i just checked the hose on the air regulator and it has a split at the end could that b the problem. no errors came up. once the car is warmed up everything is perfect.
Have you had any problems with over heating? How old is your engine? It could be the compression rings on your pistons, as when they get warmed up everything is ok. Could be your IAA aswell.
