My 95 Nissan Maxima suddenly won't start. It clicks multiple times when i first try to turn it over then seems to loose power. I can here the relay making noise and my headlights dont seem to dim when

the relay should not have any power to it. i would think there is a sort some were on the ignition. i would check the ignition wiring and make sure its not damaged or assembled wrong. relay should only get power when the key is in ignition and turned to start engine.

In rare cases your 1995 Maxima might use OBD2 but it is probably a OBD1. You could try an OBD1 reader but unfortunately OBD1 was not anywhere as useful for diagnostics as the OBD2.
SOLVED What scan tool do need 95 Nissan Maxima

You probably need a new starter. Try locating the starter and hit on it 2 or 3 times, then try starting the vehicle again......If it starts then you need a new starter.

It sounds like your starter relay could be bad.

Could be several things that caused car won't start, inculding starter, ignition, dirty or loose battery connections.

If it just clicks once when you turn the key it sounds like your battery. If it clicks multiple times when you turn the key, like a ratchiting sound, it is probably your starter.

i got a 95 maxima it has no power on the inside the windows wont work the seats the blower motor or the radio wont work either done checked all fuses and relays they are good what could it be

check first the ground connections and the terminals if they are loose. Check also the starter relay and its cables. Have the starter capacitor checked. If that does not resolve it go to the starter motor and have it checked.

It is most likely to be your fuel relay, however check your fuel filter and fuel pump.Hope this helps

Check power and ground to starter motor with circuit loaded (ie. attempting to start) If these are good then replace starter motor.
