Starting problem

Hello all my name is: Del
I have a: (GTO, TT 1990)
It has the following issue: (I have just removed induction pipes had them powder coated, refitted them, then tried firing her up it started then cut out now just turns over but wont fire, plus can’t remember where the thin rubber tube went to from the dump valve? also the metal pipe leading to the rear turbo is there suppose to be a seal there?). appreciate any help on this.
checked fuses today to try and solve this issue, found a 15amp blown fuse under dash (drivers footwell) marked engine replaced it she fired up then died and wouldn’t start?? checked fuse and it had blown again, so replaced it again now wont fire up at all??
