i had the same exact problem took it to mechanics and no one could figure it out.....til one day i was messin around and banged on the asd relay and it started....after that when it wouldnt start i would pop the hood bang on the relay and it would start until i got a new relay....i know that a relay off of a neon will work and they cost a whole lot less thats for sure....
i have a complete 420a that i blew up.....the head is fine but the bottom end is gonna need some work.....im willing to part it out...just make me and offer....bc i need to get a new bottom end or and whole new engine...thanks
