Ok, a little background first. I bought this car back in October. The car ran fine but would crank slow occasionally like the timing was too high, usually when hot. For the past 9 months the car has been getting an overhaul. I went through everything except the engine and trans. I popped a new started in it too. Today I went to start it and it cranks real slow, so slow it wont start. I assumed the battery (optima red top) was dead from sitting for 9 months. I hooked up jumpers and while it cranked a touch quicker, it was still not even close to fast enough to start it. The battery is in the trunk with 1/0 cable running from the positive terminal to the cut off switch, then to the front of the car to the starter solenoid. The ground is 1/0 to a spot in the spare tire well. 2awg cable runs from the solenoid to the starter. I have a few grounds going from the chassis to the engine. I am lost. I picked up a 600A jumper pack but I am pretty sure I will see the same result from it. I am half tempted to run a new cable to the starter and replace the solenoid. Maybe also make a big ass ground to go from the chassis to the engine. Any suggestions?
Oh yeah, I know vapor lock is a common answer but this is not the case since the car has not run in 9 months. Also you can rule out timing too advanced because I disconnected the coil with the same result. Any help would be appreciated.
