ok guys here's my problem i just put a new motor in my car and everything seemed to go OK. But when i went to start it the car started and then about 2 seconds later it turned off. So i checked all my connections and made sure they were all tight and tested all relays and wiring that has to do with fuel. When the car does turn on it revs to like 2500RPMs and turns back off right when it hits about 2500. the car is a 87 T2. thanks

 

did you check all the vacuum conections too? sounds like a vac. leak to me.

 

sounds like a vacuum leak. make sure turbo inlet duct is on all the way. then make sure you didn't leave off any vacuum hoses.....

 

actually it sounds like you dont have the intake tube or the maf connected, ususally a vacuum leak will try to rev higher before cutting off.

i second checking the manifold. same thing happened to me on my 91 n/a, but the engine also made a funny whine when it was briefly running. i had a bracket sandwiched in with the intake gasket instead of having the braket sit on top of the manifold.

thanks guys just wanted you guys to know got it started was a loose vacuum line. The problem now is the car just won't idle and stalls below 2000RPMs i tested the TPS sensor and it tested bad so i am going to replace it i have one laying around from my old motor and i will tell you guys how that goes. also does anyone know why my car sounds like a helicopter?? doesn't sound like my old motor i checked the timing and its good, so tell me what you guys think thanks again
