Replacing Spark Plugs | Chevy G20 Van 

I'm having issues with my buddies 89 G20 van. We changed plugs, wires, cap and rotor and ignition coil but it won't start sometimes. It did have a weak spark and loss of power. Runs strong now. Any ideas on what else too look at??

Im probably going to have to change the alternator too soon

you have to remove one of the seats first

No you don’t have to remove seats. Once you unclamp both sides, wiggle it out buddy

Two clamps on each side, and wiggle it out
