First of all i've tried searching the forums but can't seem to match my issue

My engine is newly rebuild (about an hours runtime)
It ran fine but had a unset throttlebody so it had a low set idle.

I did some maintenance and found that my fuel pump was crystalized along with a rusty tank. So I replaced

Fuel pump (Dw300)
Filter
Tank

Put everything back together as it was except for the new parts.

Now she won't start by simply turning the key. She is getting fuel because we can get her running by using starter fluid. And she sounds ok except for a exhaust leak from the piping under the car (loose bolt/gasket).

I don't know where to keep looking. I removed the cat to see if that was clogged and it was hard to see through by about 40% the wafer. Also the bottom stack was cracked.

Anyone have some ideas?

Edit: Forgot to mention its a S5 Turbo 1991stock

 

so starts with fluid but stay running without, sounds like a sticky afm, or lack of vacuum pull on it do to leaks cannot have leaks on this car

 

That could be an issue. I'll have to double check. Afaik I didn't remove any tubing. I did loose the charge pipe. Gonna check that and go through the other vaccume lines. Are there any common spots?
