DEAD BATTERY!?

DEAD BATTERY!?

When i turn the key it makes a ticking sound?? could it be the battery??

make sure you have all your grounds in place.

Is the motor not cranking or is it just simply not starting? Not turning over is more often used with the car cranking, but not running. Your last post makes it sound like it's not cranking.

After you've checked your grounds (specifically the grounds on the alt, and the one for your ignitor), start looking at the starter. It could simply be a bad starter selenoid. Or your battery might not be totally dead, but it may have been sapped enough by your old alt (assuming you replaced the alt because it had gone bad) that it just doesn't have the juice to crank.

well i hook up the jumper and got the car to start now but it dies out after 5-10 secs..???? could it be ground wireS??

from the sounds of it, the alternator's not taking over running the car from the battery after you start it. I would triple check to make sure you have all the grounds grounded out properly.

well the alternator ground wire leads bak to the fuse box?? is it suppose to go there?? or should i relocate it??

Take your jumper cables and connect only the negative cable from neg terminal on battery to ground screw on intake manifold.-See if your car runs more than the 5-10 secs you stated earlier.

Get voltmeter and put positive lead on alternator output terminal and negative lead on shock tower and see how much voltage is produced should be around 13-14 volts.

With the car off test ground on alternator putting positive lead on alternator ground terminal and negative lead on neg post on battery. Should be less than 1 ohm.If 1 or higher, clean battery terminals and try again. If still high recheck grounds on alternator.Check fusible links in main engine fuse box.

o yea and i was wondering could it be my ignitor chip.. cause i put in a maxima ignitor chip cuz it looks similar to the z32 ignitor?? lmk if anyone have ever try the maxima chip

Ignitor chip has nothing to do as to why the car is not turning over.Once you fix that problem move on to the next one.

If the car turns over properly and runs for 5-10 sec then you have more than a simple wire problem.

If it runs for 5-10 sec and cuts off what happens when you hold the gas in? Does it die instantly or what?

I need more details to address the problem.With the limited info you provide a little over 100 things pop in mind as to why a car would only run for 5-10 sec....

Ignition timing is one of those on the list. (not engine timing)If the sparks aren't firing at the exact time that they need to (ignitor chip) then the engine will shut off.

Yea it runs for 5-10 secs and yes it still dies even when im holding on to the gas.. ive try to check if i got spark and cycle one have strong spark but then 2 and 3 cycle have like a weak spark.So the only way to change the ignition timing is by changing the chip?? and could there be any problem with the ECU???

Having the wrong ignitor chip causes problems when the CAS sends the signal and it gets incorrectly translated.

Base ignition adjustment can be done by hand via the CAS. This is only small adjustments though.

I'd definitely recheck the wiring for ground issues. From the ecu all the way to the plugs.

Also check the ignition wires that run next to the firewall (rear of motor) to make sure none got frayed when you installed the motor.
