I recently got the codes for running lean and random misfires. I replace the spark plugs first thinking that the coil pack and wires were still good but the codes we're still coming up. So I replaced the coil pack and kept the original plug wires I got with the truck for a week until I could get new wires. My problem now is that after I put the new wires on, all in the right firing order and corresponding plugs, it won't crank or start. I've just replaced the battery since it was old and the fuel pump relay as well but same story, no starting. My question is there any way I could've messed up putting the plugs/wires/coils that would've caused this.
