its not the battery just put a brand new one in. and its not the voltage regulator either. now it wont even start up just turns over
 
you said you can here the fuel relay when you turn key yes. Anymods done to this sled? It's an 06 yes?
 
06 yes. modds would be gutted exhaust. ram air kit. pull power commander v set up. nos kit ect ect. but i took all the pcv out to test and that isnt what is affecting my sled. i think that it might be my block grounds, but cant confirm this util later
