timing belt information

[hugor]

currently i have 2008 chev trailblazer ls 4 wheel driver. when it starts it starts to shake like it wants to turn off. I am trying to find a diagram photo of the timing belt. or a more less on where it is at. it only has 71000 miles on it.

Need more specific info- do you mean it does this when the TralBlazer is moving;or is it all the time?

If all the time,probably engine issue.If so,would start with the basics like what shape are the plugs in? Bad gas? Fuel filter been changed? Would also check the coils that sit on top of the spark plugs.BTW plugs I bought last summer were about$7 each,iridium, they tried giving me cheapo ones,but they are NOT specd for TB's.Check to see if yours are correct.

If only when moving could be many other things,need more info.

This is for the trailblazer for hr i am his wife. it happens all the time when it is just parked and when it is driving. Is there anyway to aline it. the crank and cam shaft is there was to aline those to. i did check the both sensor and replaced them both. back in June or July I changed the spark plugs cause one needed to be replaced. checked the fuel injection and compression and that was all good. Also had the pistons checked and they were good. I am heisting to go to the dealer and get a diagnostic test cause they are asking for about 200.00 for that. anything else that can help please let me know

so since it is chain can it be fixed. or is it all electronical? would i have to take it in proffesionaly to get it done?

I have no idea what you are saying, what needs to be fixed relative to the timing chain? What makes you think the crank and cam are out of alignment and how could they get like that and how did you check the pistons, lots of info is missing here, wow!

If something is wrong with the timing chain can it be fixed. what happened is that when we took it in for a quick diagnostic thing from auto zone they had on the paper that the timing belt had jumped. it also had there that the crank shaft sensor code on it so we changed it out to be on the safe also the cam saft.

What is the code now, how does it run? You changed the camshaft or the cam sensor, still very tough to wade thru your posts.

when it runs it wants to turn off. then after 1 min it does turn off. it happenes when it run, and when you are driving.

Does it start right up again? If so clean the throttle body.
