Why won't my van start?
In past 12 months, I have replaced MANY parts in my 1992 E-150. Suddenly, it will turn over fine but not fire. A few days later, I was successful in getting it started. Then, a few days later again, it again cranks just fine but refuses to start (or even 'cough'). Someone suggested fuel pump. It is one thing I do not have record of changing. Where is it? And is it expensive to have replaced (with labor)?
