Hello everyone asking about my friends older van it won't start and the spark isn't the nice blue spark its all orange

Not knowing much about the van, go over the complete electrical system. Check/replace:
. Battery--ensure it's fully charged.
. Fuses--use test light or multimeter to test all under-dash and under-hood fuses.
. Check for codes.
. Spark plugs--exact brand and plug no. that came with the van.
. Coil
. Spark plug wires
. Ignition Control Module

AutoZone should be able to check the coil and Ignition Control Module for free.
