It shouldn't be,however.....when replacing batteries,or simply disconnecting and reconnecting to clear a code for example,always hook up the positive terminal first and the negative terminal last,and,with the ignition OFF.Infrequently,if a battery is hooked up with the key in the ON position,it can damage the vehicles computer....(PCM,TCM,BCM,etc etc)And the reason for hooking up the negative terminal LAST is to avoid arky sparky's off of your wrench which can also damage the vehicle's computer (s).Try disconnecting both negative terminals of both batteries and let sit for minimum 20 minutes,then reconnect,and see what you have.

We hauled a trailer about 150 miles pulled into space. Tried to start the truck back up and it just clicks. Have power. Tried to jump it but it just clicks. 2001 F350 powerstroke diesel V8


ours did that the other day. diesels have TWO batteries. for us the solution was that ONE battery had loose cables. this would give you a truck that still has "power" for lights, fuel pump, everything to make you think its normal, but it NEEDS both batteries to crank. hope it helps! i know it seems like a stupid solution, but hey

My 1990 olds cutless ciera got hot and shut off. then it acted as if it wasn't getting any gas


If this is the tech 4 2.5L it could be a TCC problem. Try pulling the plug by the battery that leads into the transmission. If that doesn't solve the problem than it might be the module.
