9 OUT OF 10 TIMES a no spark crank no start issue is the distrubiter

during the summer it can be a main buss relay.

a new dist will run you a couple hundred

a new main buss will cost under 100

having a tech look it over before waisting gobs of cash on stuff you dont need...priceless.

now if it was running right befor you changed your switch and now its dead after you finished your install recheck your bolt in fuses 40-80amp.

spacifically your ECM fuse.

thanks for the info the problem was the imobilizer-the new key needed to be coded to the car's computer. duh
