Hi all I'm new to this forum Iv got a 1.6 silver top escort
I had to change the engine in it as the old 1 blew up . I got the same age engine Ect Iv changed it . Now it will run for 4 seconds then cut out . But if I put my foot on the gas it will keep running ???
I'm a little confused as Iv checked all the wiring and it's spot on and I now then new engine run as I drove it home in the other car
Hope some one can help me ..

 

Can we get a little more info like year, model ,possible anti theft system ?
Could you have left off a ground wire someplace?
