Im not entirely sure on injectors but i do know that engines need time to warm as the internal parts are made slightly smaller than they shud be to allow for heat expansion so when you start in a cold morning this could just be the case

What will be the problem if i have a taping noise when i start my car until it gets warm mitsubishi 380


A tapping noise that starts out cold and goes away when warm is usually caused by a valve lifter inside the engine. The lifter may be worn/leaking down and will be noisy until it fills with oil pressure. You can try an oil additive ( Lucas Oil Additive ) available at most part stores works very well with noisy lifters. Another noise that can happen cold and go away when warm is an exhaust manifold leak. However, this is normally a ticking type sound rather than a tapping sound.

My toyota tazz 1300, 1999. wont start in the morning unless i give it a bit of accelerator but during the day it starts perfectly. Another problem it gives me, the engine is over heating very fast eve


Cold starting used to need a control on the car called a choke. Modern cars have a modern equivalent. It could be that when the engine is cold from being unused overnight it has a build up on the injectors and the extra push of fuel from the accelerator is helping overcome this issue.
At any auto store or garage, you can find fuel additives to clean the injectors and fuel system, in the UK we have Redex that does the job.
Find something similar, run it through your fuel and you should find the issue is better.

Iratic tick over when warm


Could be many things. Sometimes Exhaust flange joints will get a gap in them and tick. You could be hearing the Injectors, or hydraulic lifters.

The exhaust tick and lifter tick both are temperature sensitive as opposed to the injectors.

What you could do is run the engine and drain the oil and put in fresh cold oil. The first few seconds the cold oil will be thicker and if it is a lifter problem, the oil will cushion the noise temporarily until it warms. The exhaust will already be hot, so you will notice a noise on startup. If the noise generates later, its an oil related problem.

The exhaust flange problem can sometimes be heard when backing up and reversing direction. The Torque puts a strain on the pipe joint as the Torque changes from Reverse to Forward.

I hope my Solution is helpful.

I just bought a 2008 Sienna w/ 44,000 miles. When the engine is cold, doesn't have to be really cold, I hear this ticking noise (not loud) when engine is under slight acceleration between 1500- 2000 rpm....


Sounds like you are describing lifter noise. Go to the car store and buy a pint of Berrymen's Chemtool. Next time the engine is cold, pour the Chemtool into the engine oil. Do your normal driving for the next few days or weeks until you have 150-200 miles (none of them should be highway miles) on the engine, then have the oil changed. Drive for 2000-3000 miles, and do the same thing all over again. Repeat this a couple of times. If the lifter loosens up, your good to go. If it doesn't, then it will have to be repaired by tearing into the engine.
