427 with 1 Probelm...wont start HELP!
As the title says. Ls2 427 runs great runs fast 1 problem.....it wont start. I have tested battery, battery is good(12.7 resting volts). I even tried a diff battery and same thing no start. I had a volt dropping problem(stock alt bad) and the truck 145amp fixed that. Now out of no where it wont start. Noticed my fuel pump went out on me so i installed the racetronix pump and wala still wont start(yes the pump works you can hear it kick on and I have fuel pressure) Here is what has me scratching my head. The car wont start on its own but will start with a battery charger on it or a jump box.? Once the car runs it runs great not missing and volts are at 13-14 volts. But it wont start on its own seems to need help but I dont know why. Checked all grounds and +'s all good all hooked up right.
Im stuck lost and frusterated. PLEASE help...

Most likely in the battery wires. Either the ground wires or the power wires heading to the starter or alternator. I've seen ground terminals look fine from the outside but once you pull the bolt out of the terminal and remove the rubber boot the terminal and wires are all corroded causing a poor ground connection. I've also seen the AUX (+) on the driveside be loose or corroded underneath.

yes. 12.7 resting volts and when car is running 13.7/13.8 volts. When cracking the car over the battery only drops down to 10/11 volts. And yes connected battery charger/jump box to the battery. Load test shows or proves what exactly? load test the battery or the starter?
