02 Infiniti Qx4 took the stock radio out and now it want start check the battery it’s good what else could cause it not to start I even put the radio back in still nothing

SOURCE: 1998 infiniti QX4 break squeeling

some times it might be that it just needs to be sanded down or there is too much break dust. so just spray it down with a power wash and if it doesn't work try to sand down the roaters. but be carefull.

SOURCE: Battery completely dead within 1-2 hours

Disconnect the negative side of the battery. Hook a volt meter on the negative cable end, and hook the positive end of volt meter on the negative post of battery See what it reads. If it reads 12 volts, pull fuses one by one, and replace until the volt meter drops down. Whatever fuse you pull, and the voltage drops down to 2 volts, that is where the problem lies.

SOURCE: how many catalitic converters are on the 2001 infiniti QX4

There are only to Catalysts monitored by the ECM. There is a wide pipe near the front of the exhaust system that looks like it houses a catalyst, but it doesn't. Look for the rear O2 sensor, that is where the catalyst is. If the bolts that hold it on are not badly rusted, and depending on your mechanical aptitude you could replace them, otherwise take it to a shop. Have you checked the warranty coverage with the dealership?

SOURCE: 02 VW GTI Radio says CHECK

This worked for me (radio in 2003 VW Golf):
Radio says "CHECK" but is otherwise unresponsive. Turning car or radio on/off doesn't help.
On the far right of the radio, there's a round TUNER button. Press it for 5 seconds. Your screen will then show some digits, but the unit is still unresponsive.
Press tuner button again for 5 seconds. Radio should now be 100% again. Let me know if this works for you.

SOURCE: MY 2001 INFINITI QX4 KEEPS SAYING SERVICE SOON

First off, make sure that the gas cap is tightened beyond three clicks. If it is and has been then there are many things that could be causing the light to come on. But let me start by assuring you that it is not something that requires immediate attention. The sole purpose of the service engine light is to detect malfunctions of emissions related components. If the gas cap isn't tight, the computer system detects an incorrect amount of pressure inside the tank due to vapor leaking out of the filler neck. If the cap is tightened after a period of time the computer detects the right pressure and the light will go off. However, on QX4's the most common cause of the light is oxygen sensors, or cam and crank position sensors, and finally intake valve timing control sensors or solenoids. O2 sensors measure the amount of oxygen in the exhaust gas. Normally I have seen that in damp and wet conditions these sensors are more likely to intermittenly give false readings. That being said, although the SES light is not an emergency situation, it will need to be addressed at some point, as the Engine control module takes the readings from these various sensors and automatically adjusts things like idle control, and air fuel mixture ratio, and eventually will to some point affect the performance of the vehicle. I have seen folks drive 100K miles with a service engine light on, so if you don't want to spend a 200 or so dollars right away, I would take the car to autozone, have the codes retrieved, and report back to this forum, at that point I would be able to advise you a little further. But more than likely you could continue driving the car without any driveablility issues.
