i have a 1989 max .some times it run's great then other times it dont start.like it lost fuel or fire but both are there.spark is hot red spark and the fule is at 36-42 psi. i can losen the fule line going in to injc and let it bleed off and the car will start right up.it has done this to twice so far i bleed the fule line and go to start it and it start's right up so any help on this. it is making crazy

 

spark should actually be blue.
other than that I'm not much help

 

ok i look at the spark one more time tonight and it is blue .i am sorry..
