Ford van won't stay started

Hi, my sister called and said her ford arostar van,1994 I think, will start but it is rough and soon dies. I don’t know if it a fuel problem, or a spark problem. I have never worked on a van before.

Anybody have some suggestions ?



The simplest thing to look for is a broken or detached vacuum line or air intake line. This era Ford EFI is sensitive to problems with the manifold air pressure (MAP) sensor. It is generally located on one of the valve covers, Black plastic box about the size of a matchbook, and has a vacuum line running to it. If the vacuum line is detached or broken, the engine will run poorly, if at all.

Thanks, I’ll give a look.
