Was it running before the old battery went south? Did you have a check engine light before you replace the battery?
To get a 1990 Corvette to start if it turns over and the battery is good, check to ensure the fuel filter is not clogged. You also need to ensure it has plenty of gasoline.
Need a little more info. Is it trying (but failing) to turn over? What's it doing? has new battery and relay. just filled up the gas tank, it turns over and turns over, but wont fire. ends up wearing the battery down. even with a battery charger it wont fire.
turn the key? no start? check the battery connections. clean them make sure they are tight turn the key no start? turn on the headlights if you have bright headlights, the starter may be the issue. if you have no headlights, look at charging the battery after battery charge turn the key tries to start or clicks probably a dead battery if the car turns over and just won't start do you have gas? If the car turns over and tries to start that means the battery and starter are good now you need to find out why you are not either getting spark of fuel.
If the car will not start after replacing the battery, then the battery was not the problem. If it will not turn over, you may have a bad starter or bad connection. If it turns over but will not start you either have no fuel or no spark. You will have to determine which.
it was the battery. i put a new battery in it and it turns over good.
If it turns over, the starter could be dragging. Could be your battery cable along with dirty cable ends. Also, I was lucky enough to buy a bad battery.
Get your battery tested, I think a new one might be in order.
If the car turns over, gets gas and just will not start try the ignition module. CAR TURNS OVER
there is a main fuse link off the battery
If it turns over very slowly, check for bad battery and ground connections. It should turn over quickly if you jump start it. If it doesn't, the battery connections are bad and/ or the battery is bad.
Turns over but will not start or will not turn over? Is there a small wire at the battery, positive side that is not connected?
If it turns over slowly like a dead battery it could be a bad starterIt if turns over normally, but hard starting, could be fuel injectors leaking
