Can a bad alternator be the reason a 1995 Eclipse will not start even with a new battery?

It could be the starter. The alternator only charges a battery.

It could be a bad ECU, if you don't see "check engine" light up when ignition is turned to "ON" position, then It may be that the ECU needs to be replaced.

im gsboi101. If you put a new battery then it could be the white wire from the positive connection that fallen off. Check all wire that suppose to connect to the Postive side of the battery.

i had a problem like that and took it to a shop it was a relay sensor behind the dashboard.it cost around $120. to have it fixed.

I had a similar problem, get a gage that will test the charge of your battery. Test the charge, then take all the wires off of the red clip on the battery and test again to see if it's the same charge, if not - one of those wires is holding ur battery down. Try playing with it - taking off only 1 wire a time and testing it's charge until u find that one wire. U will quickly learn what this wire does, mine turned off my inside car lights, radio, and the ability to roll up windows when car is turned off before i open door. to know if it's ur alternator, turn on ur car, then take off the red clip from the battery. if the car stays on, it's not ur alternator. Ur battery only starts ur car, the alternator holds the charge to keep it on. So if the carn turns off when u take off the red clip to ur battery, chances are - it's ur alternator

If u have an off market alarm, this could do this too. I had a kill switch on my Prestige alarm, and i had to completely remove the alarm when my alarm started acting up and my kill switch was disabled.

We probably need more information. You can pretty much guarantee it's not the alternator.

Does it turn over at all? If it DOES then it's not the starter, battery or alternator. You need to make sure you're getting spark and that it's not something a little deeper than you think. If it DOESN'T then it's probably the starter, the starter solenoid or the main fuse. Check the fuse box and make sure all the fuses look fine. Your next step would be to replace the starter and/or solenoid after making sure the wires to them are not broken somewhere.

The most common reason for a vehicle not to turn over is a bad alternator. If the alternator is not charging the battery the engine will not start, regardless of the battery age.

Check your alternator--a lot of times they go about the same time (for no reason).

As long as the battery is fully charged it will start no matter the condition of the alternator. Eventually the battery will run down if the alternator is not keeping it charged.

Yes, the battery starts the engine, and as long as the battery is fully charged the engine will start. The battery will loose it's charge if the alternator is defective and not replenishing the charge of the battery but the alternator has nothing to do with starting the engine.

It will start if there is enough charge in the battery to turn the engine over. However if the alternator is weak then the battery will not be charged fully.
