It could be a tooth off or too advanced and cause this to happen. Kristen June 1, 2012 at 11:13 am I agree with FreeAutoMechanic, but also if the battery connections are loose, dirty or the wires are too small, like if you put the battery in the trunk, you will need larger battery cables. marvin June 17, 2012 at 4:52 am a new timing chain has been installed. it get gas on a good turn, then the battery get weak. put a new ignition coil, but can:t spend enough to keep the mechanical fuel pump and ignition going. marvin June 17, 2012 at 11:22 pm i”m still having trouble wit the olds 98 307 engine. the battery dies out so quickly, do you think i have a elecrtrical ground? Freeautomechanic June 18, 2012 at 10:44 am Probably just have a weak/bad battery. If you have a bad ground or loose connections the cables will get hot after trying to start the engine.
