I have a gmc Sierra high s15 1982, the truck is not starting, we change wire coil, we change the router cap and nothing. It's cranking but not all the way. Any ideas?
It's sounds like it's going but nothing.
Check all the spurk plugs. Everything
has a spark, please help?
is the Batt a full charge are your +Pos_ -Neg wires making good connections. if all is good then did you move the timing by chance? Or did you make sure all the coil wires are on good. Did you hook up the HEI power wire on the coil, if you did not it will crank over but will not start. Re check all simple things that you did first. Did it run before you did work?
