Help Spark disappears????

Any help on this.

 

Replaced injector caps and reinstalled plenum.

 

Car won't start just keeps flooding + the spark starts nice and bright then fades to nothing. Also one of the coil pakes looks like it melted.

    Paul C[/u]]PTU??

     

    have you tried replacing the coil pack?

     

    everyone is saying PTU and I know it makes sense, but I just want to cover all bases.

    just wondering how the PTU could cause a melted coilpack?

    If one of the PTU transistors went short cct then it may feed a constant 12V to one of the coil packs causing it to overheat?
