94 s10 4.3 wont start
Plugs wires cap fuel battery and alternator are all good.
Truck spins over but wont start. Sometimes when I crank it
makes a whining sound like fly wheel maybe.
Does it have spark? Pull a plug wire and test. If not, you have an ignition system problem. Does it have fuel? Starting fluid is the easiest way to check (remove air filter and spray a bit in to see if it starts). Does it have timing or compression?
Yes coil and plugs are all new. And fuel tank if gas pump is working fine.
