So you guys.. i got a 97 Ls with a Jdm Gsr Bottom end and Type r head. i recently just changed the intake manifold. now all of a sudden my car wont start. we had to push start it. check the battery and it was dead.. and got it recharged.. and i hooked it up to the car and within a matter of min the battery is dead again and the car wont start. i have a feeling my radio and headlights are wired wrong because one time at the gas station i left my lights and car one when i pumped gas and after that the car died.. so any suggestions?

 

A batt. will not "die" "within a matter of min", more then likely you have a connection problem, check batt. to chassis and chassis to engine grounds. 94

 

One other possibility is that you killed the battery. A recharge will sometimes give a surface charge and you measure voltage but no amps behind it. That may appear to die in minutes, but was really dead and did not know it. Connection more likely unless battery was old and dying anyway.

 

alternator?
