ok so i was changing the plugs out and the ratchet hit the +pos side of the battery lead. i went to start it up and nothing at all worked. checked every fuse and relay and nothing was fried. put my spare battery in and started right up. so i went later to go drop off the other battery at the autoparts store and it wouldnt sart up. so i popped the hood and tried again and i saw an arc come from the +pos side of the lead and itstill didnt start. nothing works now and im bck at square one. what should i do

not you battery. Check the ground wire.

loose connections at battery or worn out

ok so it seems my ground is good and so are my connections. i put in an optima and still no start. bells and lights stay on momentarily but when i turn the key it clicks and everything shuts off. could it be my altenator? or maybe the leads or wires

Do you have fuel pressure and spark?

mine did the same thing i had to change out my connecters on the end of the cables that connect to the battery

thanks you guys. come to find out it was the battery. they were all three dead. weird haha
