[slaughtermimms]

For anyone; I have a 95' Q45 w/about 98,000 miles, would not start jumped started right away. drive for about a day no problems. Went to get food, would not start, tried jumping again would not start, took battery had checked came back w/ at less 600 cranking amps, battery one and half yrs old 84 month from Infinity. Took it to shop had put in new starter, will start however if it is turned off, will not start. We are thinking the security system will not reset, can someone tell me what to do or how to to do it. Please help, I need to get car going for job, been out of work for two yrs. Someone please help dont have alot of money dealer. Again HELP PLEASE!!!!MY EMAIL: [email protected]

I think Infiniti dealers still use Interstate Batteries which are great batteries but like anything else will die if abused and neglected.

The security system most likely is not the problem unless the horn is defective and one of the Anti-Theft relays is malfunctioning. As the lights would also flash and the horn would sound alerting you.

Check the alternator and load test it (All electrical equipment in the car on) and check to see that it creates 12.5 volts or more at idle with a full load. This is a simple test that can be done with a multimeter or Nissan Consult (Or equivalent).

Well, great to see one of the original board members back.

Wonder if you might have to trace this one. Neutral switch? Just a guess.

Not sure if Interstate or not it has Infinity lable on it however and the gen. and starter have been tested, starter was bad replaced, still does not start. Thanks everone for the input, still will not start,but everthing else works, raido,windows,horn,lights.....etc.

Does the starter even turn over when you try to start it?

Check the starter relay and replace with a known good one if available since its a easy fix.

Glad to test and share my knowledge.

No the starter does not turn over or even click,all relays fuses wires and fuseable link have been checked and tested by the shop, I have also supplied them with service manual. the battery has 600 to 620 amps under load. The shop can start the car and it will run fine UNTIL it runs out of gas or it is turned off; then it will not start again. That is way I was asking if there is a way to reset the security system. OH almost forgot; when you contact battery cables there is NO spark at all. Hope this helps

If you have a good battery and good connections at the battery the jumper cables should spark like crazy if the ends are touched together. Are both clamps connections at the battery posts secure and tight? The OEM negative clamp wears out with time and doesn't grip well. I had to slide in a piece of lead to get mine to tighten until I replaced the clamp. To verify, check continuity with a volt meter from the negative battery post (not the clamp) to the ground on the chassis. Do the same with the positive cable from the battery post to the connection at the starter. Also clean up any corrosion on the clamp or post at the battery and the connection point on the opposite end. You could also have a bad battery that's not holding a charge or a dead alternator but you'd have warning lights.

If it's a security issue (doubtful) turning the key in the trunk lock should reset it.

I have done everything you brought up and more, cup holders look nice, but would not work in a 95' Q thu, I just do not know were to go from, ................to the dealer and take out loan on my house to pay for it. I want to take this time to thank everyone this has responded; of course there has to be a fix

Good to hear from you, how have you been doing?

[Infinitiguy19]

I doubt its a ignition switch but thats possible. I am still thinking battery or alternator. Or sticking relay is causing the battery to drain too fast?

The battery terminals are clean as can be, right?

Boy this forum sure is slow!

Battery and altermator are good both tested, relay was weak replaced, terminals cleaned as clean can be, plus a little deleic grease. I guess see what the shop has found out, and then to the dealer, no choice. I want to thank everyone that has given feed-back. Dont give up on me PLEASE!!

[blacklist74]

I had the same problem. It was my starter relay...

[Infinitiguy19]

The dealer will not be able to find the issue easily and cheaply if we can't online.

When the car can not be started is the battery at least at 12.5 volts?

Can you tell us the battery voltage at different conditions?

[maxnix]

BINGO!

Get under there and use some well placed hammer persuasion.

Interstate batteries went from Fort Worth to Mexico two years ago, along with Optima. Dekka and one other is still in US.

I want to thank everyone for the responce to my post; GOOD NEWS! The Q is fixed.......to start with, the starter was burned out plus the starter relay was also burned out, both were replaced and the shop still could not get it to start. Took it to the dealer......they first tell me it was going cost $500 to over $1000 to fix. GREAT NEWS GUYS! .......the mechinc found a wire going to the starter relay had come lose, SO BE ON THE LOOK OUT ending cost $125, first shop were real good; they did not change me because they did not fix it. Thanks again for the support!
