Ok so I just got my car from the shop they put in a new lower intake mainfold. The car ran so good home. When to pull in my drive way and the car idle really hard (like it was out of gas) and died. went to start it back up it start but runs like crap and dies when it cuts off it makes this noise like when and bus or big truck stops its a pushhh sound. I called the shop back and they said its nothing they did the car ran fine on the test drive so i dont no what to do now


thanks for all the help ahead of time

 

First Get scaned 4 any codes.. Auto zone, its free..

 

How can i get it scaned if it doesnt run can i get them to come out to my house ????

 

My bad, Ok check and see if your hose 2 your map sensor is connected. Lift your hood look on the left side of you Air intake plenum. It sits towards the back. Its a black or gray little box looking thing, it will have wiring harnest connected 2 it, And a thin hose under it..
The thing you have 2 look 4 is that hose. Make sure it is connected and not dry rotted, or melted.. That little thin hose runs under the Air intake plenum into a T .. The right side runs 2 the fuel pressure regulator, and the left go s 2 the back of the plenum..
you wont believe this, But that little hose could stop your car from running..

 

My car is having a similar problem. I rebuilt my heads and had to replace my wiring harness cause some rats ate my entire harness pretty much. I did notice that they ate the boot on the little hose for the FPR. I just used some electrical tape at first and my car ran ok for 2 days. Then yesterday it wouldn't start up. The fuel pump works cause I can hear it but I need to check the fuel pressure but it needs to run to check the pressure correct? My car has a hell of a time starting and then dies like it ran out of fuel a few seconds later. Im running out of time on fixing this thing too so any suggestions or help would be appreciated.

*Edit* I didn't know this was for V-6 engines. I just did a search on fuel problems
