I've done some pretty silly things and never blown a VN computer (delco) by shorting it out or jump starting. See if the computer will go into diagnostics before you do anything.

I explained it quickly here-

If you have a multimeter check your coil pack/s and DFI module.

over the year's i did my appentice ship for auto spark, i would often see some people come into the shop with car's that had no spark, well, i have good new's and bad new's.

good new's, your computer is fine, the bcm dont realy play any vital part on the spark side of things, it does have a funtion but not to make spark.

bad new's, igntion moduel is stuffed, if you have no spark, it wount be a coil, vn, vp have 3 dual coils, so unless they are all dead (which i doubt) you wont have any spark there. how ever if the ignition moduel is dead, you will have no spark, the igntion moduel controls the coils. ill write up a little dity 2morrow on how to check your ignition moduel


cheers

p.s. when you want to get a new igntion moduel, first you should check your old coils, why replace something that isnt broken. you can just get the igntion moduel seperately without the coils. it will save you a **** tin of dollars aust there.

Unless the VN is the first series which used 1 big coil (from my understanding). The second series VN used the 3 separate coils.
