2005 suburban cranks but wont start
after jump start truck has no interior light with opening and closing of door .
power lock don't work and it will crank but not start
Battery is OLD...7 years and they go stale and put out reduced voltages..and cannot accept a re-charge anymore....but the cables from Black clamp to the block and the black clamp to the chassis/fender should be able to pull 60 amps CCA...you might check the grounding at the coil-pack~ think most likely it's Corrosion on the battery and connections to the chassis at fault here~
