also i know how to check the fuel pressure in the rail i already checked that multiple times
You never said that, you just said there's fuel on the plugs and you smell gas. We can't read your mind, you must tell us what you've done. ALL of what you've done.
i am getting spark fuel and air thats not the problem it just wont start.
There's no such thing as "just won't start". If it won't start, there's a logical reason. Maybe the fuel injectors are damaged from your rebuild. Maybe the valves aren't seating. Maybe the cam's 180 deg out of timing. Maybe there's a cat stuffed in your intake manifold. Maybe the ECC is fried. All we have to do is find the reason, and all the suggestions we've made to you are intended to find or eliminate possible reasons.
i checked all the pistons and block for cracks when i took it apart there were none. all it does is crank over it doesnt fire at all
I didn't ask if the block was cracked...I asked you to check the compression. There's lots of reasons compression can fail, and poor compression will keep your engine from firing in that cylinder.
Do you have a printer? Print the suggestions out, try them, write notes on the same paper, and the RESPOND to those suggestions. When somebody says "Check
X" then you should post back something like "I checked
X like you said,
this is what I did, and
this is what I found, I think that's normal, is it?" or "I checked
X when we put it back together, and I think it was fine, because it was like
this. Is that right?"
If we could get some responses from you, we'd know what you've checked, what you haven't, what problems may remain, and what problems you don't have.
We can't wave a magic wand and say "Poof! Replace your Giz-Widget and your truck will run again!" We can't call you on the phone and talk you through the process, it likely will take many hours of wrench time to zero in on the actual problem.
If you can't communicate back to us effectively, it's probably better to just take it to a shop and pay through the nose to get it fixed.
