It broke a rocker arm, could not find half of it, I fixed it. I am getting gas, spark, I checked timing, and no codes. Still no start.
Please help.

Can you see if the engine has compression before we get too deep?

Here is a guide to help us get started:

You can rent a gauge for free at the local auto parts store.

Please let us know what happens.

Cheers, Ken

Yep! That is no good. Please test the rest so we can confirm a timing chain issue.

The rest had 60 to 100 so I check the timing marks on a timing chain got number one plug up an the marks are 12an 6oclock, but the crankshaft ones are off. I tried to send pic but I guess I done it wrong. Theres sumthing getting caught because every 5 to 6rounds it gets stuck, I have to turn it back a little then it will go ahead an turn. I think something bent or the rest of the rocker armis in the engin

It does sounds like the timing marks are off and the chain needs to be replaced, the only bad thing is it sounds like you have bent valves. When you say you had trouble uploading picture what happened so I can get the problem fixed?

It is expensive, this kind of repair can go as high as $2000.00 you might what to think about a new engine.
