1998 GMC Sierra V8 Four Wheel Drive Automatic 200000 miles
Truck first started missing out at low rpms and then one day it wouldn't start. First thought it was the crankshaft position sensor but I tried a new one and it did same thing. So I hooked battery charger up to battery and then tried to crank it over to see if it had spark and it about started with one plug wire off. So put wire back on and it started but it missed out when I drove it. It continued to not start ever since unless I have battery charger hooked up. When I try to start it up with out charger it just cranks and its rough sounding and sometimes it hits and about starts but just back fires and never runs. When battery charger is hooked up it usually starts but cranks a few times and acts like timing is off. It used to always start right away. Please give me some advice on what it could be. Thinking something with ignition or distributor or some sensor.
have the same problem?
