replaced timing chain tensioner, no start now :(

Please help. I just installed a new timing chain tensioner from the dealers due to a bad rattling noise. Everything went smoothly until I tried to start. The engine turns over but doesn't catch! Checked fuses, they were good. I removed the valve cover and the chain was as tight as it could be.


Curious, where is the orange link in the timing chain supposed to line up to?

If you did not remove the timing chain the marks should make no difference. Why do you ask?

I don't remember off hand which colors match to which points. There are 2 or 3.

I am thinking your problem is the chain and/or guides rather than simply the tensioner.

Year, model, engine, mileage would help.

Sorry Don. I should know better. 07 HHR, 2.2, 130k, auto.

The truck ran before I changed out the tensioner, although it sounded like something was loose or clanking. I was hoping the tensor would take up some of the slack in the chain, which it did.

I ask about the Orange marks because they don't seem to line up with the marks on the cam. Are all the marks Orange?

Well.... there are 2 colored links that match up to the int & exh arrows on the cams and one that lines up to the TDC mark on the crank (which is not where an old guy like me would look for it; it's at like 172 not 180).

Darn, so it must have skipped when I released the tensioner... How many teeths would it have had to of gone to do any type of damage to the head? Do you think I could reset everything, and everything still be ok?

So I'm thinking of...
-Jacking up the front
-Removing the valve cover
-Removing the spark plugs
-Rotating the crank to TDC
-Removing the chain tensioner
-While holding the chain up, rotating both cams to TDC
-Realigning the chain to the cams
-Replacing the tensioner
-By hand, turn over the engine a few rotations and check
-Replacing valve cover
-Replacing plugs

Does this sound about right?

I don't remember the colors. You basically line up the cams then the crank.

The way the guides are set up you MUST NOT turn the crankshaft counter-clockwise or it WILL jump at tooth.

Alright thank you for the tips. Hopefully I can realign everything without there being any damage done. The tensioner came off pretty forcefully, but I've replaced them before and never had any issues.

I'm hoping I can still get everything set without removing or dropping the engine.

Alright so correction.

Make sure that the left camshaft intake diamond is facing inward towards the right camshafts exhaust triangle (also facing inward), and the orange links will be placed on the outer 10 oclock exhaust triangle on cam 1, and the intake diamond on cam 2 which is at the 2 oclock.
