Okay. I'm new to 350s especially new to vortec 350s. The issues: this truck was a bargain deal. The previous owner said that the truck ran and drove. Battery went dead. They bought the Walmart special and didn't notice that it was reverse posted. After they hooked thebattery up, it blew a lot of fuses and it had no spark. They replaced all the fuses, computer, and cam sensor. They got fed up and soldit to me. I work at a scrapyard, and we've got another 97, so after some testing, I determined there was no spark coming from the coil, and replaced the coil/Icm assy. Now I get spark. But it does not fire. If you open the butterfly, shoot ether down the hole, and crank, it pops in the exhaust a bit and has sounded like it wants to start. It just wont. Any suggestions? I understand these are spider injected? Would that have something to do with it? Any help would be appreciated
