Car won't start! Need help asap

[brendanl96]

I have a 1990 300zx and it wont start. My lights and radio all turn on but when I go to try and start the car, I get no response.There's no click or anything when I turn the key. I already disconnected the battery and that didn't work and then I tried jump starting it and that didn't work either. Can anyone tell me what the problem might be and how to fix this please?

there might be something called a starter relay that might be bad, check under the hood on the drivers side there is a black box pull the cover off and you will see some green and blue relays i think there is one for starter test it to see if it is good or bad (service manual will show you how to check them) once again im not 100% on this but just something to check

starter relay is in the driver side wheel well in the very back of it, just bolted to the body not in one of the fuse boxes (as per TT.net)

thanks for the correction lol do you think this could be his problem ?

I think your right about it being the starter relay.Im going to replace it and see if it works

[t.mcginley.jr]

Its cheap and easy to replace, so if it works or doesn't work it's not a big deal. It sounds like this is your problem and your starter is not making any attempt to start the engine because it probably isn't getting any juice. If you really wanted to test the starter you can apply 12V directly to the starter (bypassing the starter relay) and see if the starter turns. If it does then you know its the relay. Also if it was just the starter, jumping it should have worked.

Yep..starter relay

My car just started doing the same thing haven't checked the relay though... But while I try to crank my car it drains my battery power.. Is that still a sign of a bad starter relay??

[brendanl96]

I had your problem a while ago and if you try to jump start it and it doesnt start then it is your starter relay

[t.mcginley.jr]

I had your problem a while ago and if you try to jump start it and it doesnt start then it is your starter relay

This. If you jump it and it starts then it's probably your battery. AutoZone or any parts store should be able to test your battery and your starter. But if you apply 12V to your starter and it starts then its your battery.

If the relay is bad will it make a sound
