2003 Nissan Pathfinder - Answered Questions & Fixed issues

I think you could use this manual method instead.. My nephew use it to repair my car and it's totally repaired now. Here's the website he bought it from. reliable-store

Your owners manual should have a troubleshooting chapter. It also has codes many times for tire pressure causing lights to go on.

run the fault codes could be low fuel pressure from the EVAP system not venting the tank properly but the codes will point to the fault area

Not all coolers look like radiators. I wouldn't think it should cost that much. Try somewhere else.

Check for a loose ground cable connection and inspect the distributor and inside the cap for excessive wear or signs of issues like leaks or metal shavings.

If your issues are related, it sounds like you have a bad ground somewhere. I suspect you have two separate issues though. The starting issue sounds like you have a dead spot in your starter, which is the beginning of the end for that starter. Your A/C issue sounds like either a bad pressure switch in the pressure side, a clogged filter/drier, or a compressor starting to fail. I hope this helps.

Need a scan tool to perform this function.

This could be so many things you need to run basic tests. Fuel pressure correct? Nice fat blue spark? Clogged exhaust? TPS?

Your question is too broad, in my opinion. What kind of problem are you having, fuel--ignition--something else? Your local automotive parts store should have a parts book. There are several online parts books that you can look at for free. rockauto.com is just one of many.

most likely the IAC valve is bad , which damaged the ECM also. Have replaced couple of ECMs for this code in 2003 pathfinder. P0507 is an ICS code , which is linked to faulty IAC valve., but the ECM is an issue also, most likely. Find ECM on ebay. and replace the IAC valve with new one. Wait one minute, your model pathfinder also has giant recall for strut towers rotting out, so have your local dealer check your VIN for the campaign. if the car is rotted beyond repair in certain areas by the struts, Nissan will buy the car back and give you money for it. Check the vin with your local dealer.

There is a paint on rust converter . You paint it on the rust and it turns it back into metal . After that i would spray the rubberized under coating to protect it.

There is a left and right switch if they both are

Have you checked the throttle body to see if the ventury butterfly is operating properly? Its most likely a fuel prob. You may want to check fuel pressure as well. So e parts stores will rent or loan a gauge to check it at the fuel injection rail at the intake manifold. I would start there to make sure you are getting proper pressure and volume. Ask your parts store or dealer for what pressure should be. And make sure you leave the guage on for ten min or so while the car sits not running to see how fast pressure falls.

Check engine light on? Could be catalytic converters. No engine light. Have history codes read.
