So I’ve been having problems with my TL, whenever I start it the car doesn’t start. It takes about 3-4 times then it will start up. I checked my starter , I’m thinking it’s the ignition switch. Really not sure.

 

You need to be more specific in the details in order for us to help you. IOW - help us help you. What year? How many miles? Does the engine turn over every time you turn the key? If the engine is turning over, it's not the starter. Are you seeing a flashing green key on the dashboard? This would indicate a security issue and your key not being synched with your car properly. My guess is because it eventually starts, that isn't the issue. You need fuel, air and spark for the engine to start - start there. Can you hear the fuel pump prime when you turn the key to accessory mode? How old is the air filter? How old are the plugs? I could go on and on.....................

 

I have a 06 TL , my car starts but it’s like it needs a few tries for when I’m turning the key. All the lights come on in the dash.

 

Not to mention my car has 160000 miles. I think I need to change the air filter now that you mention it but could that be a reason why it doesn’t start right away

 

Hard to diagnose over the interwebs here, but a severely clogged or block air filter could restrict air enough that it has trouble starting.

 

 

That's the cabin filter and long overdue (years???) for replacement. Go pull the engine air filter and I can only imagine its going to look the same. At the end of the day replacing both of these filters may not solve your starting issue but at least you will have knocked off two maintenance items.

 

I just checked the engine air filter it looked brand new

 

Does the car crank everytime you turn the key or are there times where it doesn’t?

 

It has times where it doesn’t crank but it will eventually start up. I’m thinking it’s the spark plugs this TL has 160,000 miles. Previous owner didn’t keep up on maintenance at all. So I’m going to check those spark plugs tomorrow asap.

 

Plugs are always good to due if they are due. Sounds like it could be a starter issue though to me.

 

I had a shop look at like 2 weeks ago they said my starter was good.

 

thats the worst cabin air filter ive ever seen!

 

Just put in new spark plugs yesterday, the car still having trouble starting in the morning but luckily it started running.
