Car ran perfectly before changing by valve cover gaskets and disconnecting my spark plug wires to organize them. I plugged all the wires back where they should be, I tried to start the car tonight and while turning over, poof sound up and out of the Sniper throttle body. I tried to crank it a few more times, would not start, only just turn over and then poof again, but this time it fireballed. Checked all spark plug wires by disconnecting and then reconnecting. Unhooked everything from the battery let it sit then reconnected. Will not turn over, I do have fuel pressure. Might be a timing issue from what I’ve read, but not sure how the timing could be off. Any suggestions?
