My chevy 95 Tahoe has been parked for a while with no battery, now I put a new battery, it cranks but won't sta st?
I ran into a similar problem with a Cavalier, turns out that the on-board computer needs to have constant power. Even if the battery is very low or even dead, it still has to be connected. If the battery is removed it breaks the circuit and stops the command that lets the engine start. After the new battery was installed it would crank but not start, the dealership told me that I had to have it towed to them to have the comp reset, which would have cost around $150 total. Thankfully a mechanic friend of mine had a diagnostic machine and was able to reset it for me - cost me a case of beer. He then showed me a (not so simple) trick around this for the future. Once it is running again remember this. 1 Have the new battery and jumper cables ready, 2 Loosen the battery terminals on the dead battery but DON'T take them off. 3 Connect jumpers to the car battery cables and to the new battery, like you were jump starting from just the new battery. 4 Remove the terminal cables from the dead one in the car and remove dead battery (be careful not to let them come off the cables OR the good battery) it's OK if it disconnects briefly, but reconnect it A.S.A.P. 5 Put the new battery in and connect the terminals BEFORE removing jumper cables. Once they're on the terminals just take away the jumpers and tighten the nuts. That's how you change a battery without letting the car ever lose power. Hope that helps Jose. Good luck, safe driving.
