Timing Chain, or Spark plug or bad gas reason for no start?

[KansasZj09]

Alrighty, thanks, will do. I am also going to try to hook up my neighbors scanner to the car, just for giggles.

i used an impact to get the bolt off the crank pulley.
then i rented a puller from autozone to get the pulley off.

then you can take the timing chain cover off. i just did this last week on my 97 sunfire.
once the cover is off, you can take off both sprockets and the chain, but before you do so, make sure the timing marks on the old sprockets (gears) match the new ones. rotate the engine so that the timing marks on the gears line up with the tabs on the tensioner before removing the chain.

If the engine jumped time, you'll be able to see it right here. If the timing marks don't line up on both gears, get the cam set (by turning the crank until the cam gear lines up with the tensioner tab), remove the chain, then move the crank until it lines up. you'll prob have to put the hub and pulley bolt back in to turn it.

with the chain off, you can rotate the cam and crank shafts freely to get them lined up. (the crank may move a little while trying to get everything off). you might as well replace the tensioner with everything else.

Thanks. My neighbor is going to try to fart with it tomorrow hopefully, he had me remove the starter as a start and see if the teeth on the starter where the flywheel goes into was messed up, or moving backwards and it wasnt, so tomorrow he said he was going to look at the flywheel and see whats going on with that, and im sure everything will be fine with that least im hoping. Chances are Im sure it has something to do with the timinig still being off, and he will probably mess with that on a weekend or something.

I took a video of the car, and trying to start it, and the clunk noise however it was on my phone and idk how to upload it on my computer

UPDATE: My neighbor mechanic today tried to turn the flywheel over manually. It wouldnt move but a few small spins when he tried moving it clockwise, he said there was resistance. Then he tried moving it back counter clockwise, moved quite a bit, then hit resistance again. He said that sounds like bad news, however im still not convinced my timing is correct still. Also I heard from someone else that trying to manually turning over the flywheel and it having resistence is a good thing because there is compression, any takes on this? Thanks.

[viggy58]

yes, you will def meet resistance on the compression stroke while turning manually. the best way to make it a little easier is to remove the spark plugs, so the compressed air can escape. that will lower the resistance.

Alright thank you much for clearing that up. Tomorrow I am going to try to investigate more, i hate $3.50 a gallon for gas, my Jeep is killing me, I get 10 to the gallon in it haha, so i def want to get this car fixed

With the plugs out it should be fairly easy to turn the crankshaft, but even so you will feel a decrease in the resistance at two points. Both of them will be when the pistons are at top-dead-center at the end of their stroke. Two of the pistons in a 4 cylinder engine will be at the top, while the other two are at the bottom. The point of least resistance will occur when the crankshaft is 180 degrees away from the previous point of least resistance. At this point you could just about turn the crankshaft pulley by hand. With the crankshaft turned 90 degrees however, you will be moving the pistons up or down in the cylinders, and will feel the resistance of the piston rings on the cylinder walls.
But all this involves smooth silent gliding movement. If there is ANY point where turning the crankshaft pulley suddenly encounters a definite increase in resistance -- then something is very wrong. It could be a small chunk of something in one of the cylinders, getting squashed between the piston crown and the combustion chamber in the head, or a damaged lifter, or something jamming the timing chain like a small piece of plastic or metal. There are worse things it could be; like a bent connecting rod hitting the block on its way up, etc. Anyone who has some experience in diagnosing and rebuilding engines would probably be able to feel the difference between good and bad resistance.

kansas,time to pull the cylinder head (front 1 atleast)!!
if you can not turn engine over 360
then you have a bent valve,bent rod,or maybe a hole in piston.
sorry but i think your putting off the inevitable......

Thats how the old one looked like when i pulled it out, this is the new one that i put in, and replaced. I just happened to have pulled the first three out. 2 out of 3 were fine, this one is not, the gap is closed and the prong is touching the spark plug, and the first 2 or 3 threads look damaged. The car hasnt even ran or started since i put the new ones in. Oh and this is the same location as the old spark plug that got destroyed. The middle section on the front.

with it bent closed like that i hope you never put a hole in the piston? i would run a thread chaser therw the cyl's before you have to put a helicoil in it.

My brothers cousin messed up the rear spark plug threads in the middle whenever my brother had it, some how he fixed the threads? Im wondering if this kinda has something to do with this spark plug being jacked like this. Although this plug in the picture was pulled from the front middle, not rear middle where the threads got jacked.

like i have been telling you there is internal problems with your engine
you need to pull the heads,how many clues do you need????
no offence Kansas but your wasting your time............

[KansasZj09]

Alright, well in all honesty, I am trying to start with small things and then work my way up to bigger things if that didnt work out, that was the reasoning behind stalling on pulling the motor apart. I dont want to pull the all that crud off and then it be something else. Thanks for your input though, and yes i will get the heads off. I just dont have the knowledge of doing that so i was hoping like crazy i could get lucky and find something that wasnt as serious, guess that proves my luck, oh well, if it ran then i wouldnt of gotten the chance to have the car then.

Does anyone happen to have a guide on how to remove the cylinder heads? I am clueless and was hoping to find a good instructional video or instructions to get to the heads, and also to remove them. Thanks in advance
