I pulled off the upper intake to replace the vacuum lines on the bottom and because my idle was jumping around everywhere and I had a leak between the upper and lower intake manifold. Put it back together and now my car wont start. It turns over, you can hear it firing like it wants to but it wont completely get up and going. I checked my fuel pressure (40psi), everything is firing (from coil to spark plugs), and its sucking in air when turning over. I have checked over everything two or three times and I dont know where to look anymore. Please can someone give me some recommendations!!!

Check all of your connections...maybe you left your tps or something like that unplugged.

Also check the connection to the injectors. Make sure all of them are connected. You might have pulled one or two of them off.

Also, triple check all of the vacuum connections. If you forgot to connect one large hose (or several small ones), it could pull enough air to not start up.

you might not have sealed the upper intake to the lower. did you hook your PCV back up?

i say timing, did u move the distributor?

^^^ yeah it does sound like a timing issue

it is always a timing issue, because everyone forgets to put the motor at TDC before they take it apart, that is something my dad got me in the habbit of doing puttin it at TDC before you take the dizzy out it makes it so much nicer when you go to start it again because it should start.

All the hoses are connected, checked all injectors and they are all connected. Timing shouldnt be a issue considering I only pulled the upper intake off and never touched the distributor. Also the pcv valve is connected. I hooked all the hoses back to where they were connected to originally but the previous owner could have had them wrong...could someone let me know where they go so I can make sure I have them connected right. Thanks for the replies guys but still no luck.

Really frustrating since It ran descent before and when I found like 4 vacuum leaks and got them fixed I was thinking she was going to be running in top shape and now she wont even start. [:@]

Check this vacuum diagram, I think it should be of help.. If you need other vacuum/wiring diagrams you can check them at http://www.veryuseful.com/mustang/tech/engine/
