ok so last week i had a paxton novi-1000 installed on my 1993 mustang 5.0, and ever since i got it installed my car has been having trouble starting, like it will crank but it will not start but if i check it 5 hours later it might start up, today i missed work because my f^**#!% car wouldnt start and its really starting to piss me off and i have no idea what it could be, i brought it back to the place that installed it but when i brought it back it was runing fine but its craps out alot, any1 know how to fix this or what the problem can be?
