Question about 2002 Ford Explorer

2002 explorer wont start

My explorer runs great most of the time. But about once a month when I go to start it , it will do nothing but click. All my lights are bright, everything works. I can hook boost cables to it from a running car and it starts straight up. Even without letting it sit and charge I can turn it off and it will then start back. I also can not just turn my ignition to the battery setting without starting it all the way for longer then 2 minutes or it has to be boosted. I have put the thick good battry terminal ends on it. I have had the battery & alternator checked and they are both working fine. I noticed it is worse on days it cold. could it be my battery isn't strong enough to pull my big V8 engine ?

You have the symptoms of a defective starter solenoid, the large contacts inside the starter solenoid get eroded over time and finally start to not make connection, that is the click and the no start, in most cases you can get it started by repeated attempts, but in the end it will strand you. The starter solenoid can be rebuilt for about $10 and an hour of your time to remove the starter from the truck.

Hi Custerd8t,

I'm sure you checked the terminals were clean and tight.
From your description, the symptoms still point to the battery(s).
Extreme temperatures can have a negative effect on them.

Question: Do you have a dual battery setup? You mentioned Batteries.

While a battery may read +12VDC on a volt meter, it's ability to deliver enough Cold Cranking Amps to turn the engine has been reduced. This is sometimes referred to as a 'Surface Charge'. It has the voltage of a fully charged battery, but not the performance of one.

But no one likes guessing games. Here's how to either confirm or rule out the battery as a problem.
It's called 'Load Test'. It tests the voltage under a simulated load, like turning the engine.

Most battery or auto parts stores will do the test for you for free.
Even though it works during the day after you get it jumped, the Load Test would still read as 'marginal' rather than 'good' if there is a problem.

At the same time, have them test the voltage while the engine is running to check the alternators charging capacity.

If the battery fails the load test, the acid level may be low. I don't know the type you have. If it's not the sealed type, it may be fixable. Otherwise, replacement would be necessary.

At this point I've stacked up three or four 'If's'. Let's see what the Load Test says. Get back to me with the results, we can proceed from there.

Good luck,
Mike

its the starter the solenoid is grounded though the starter when you put positive power to
the solenoid its grounded through the starter windings. when brush's start waring out
the stater cannot keep the currant constant under the load of starting the engine. but out of the car
the starter will run. if you bypass the solenoid it can not engage the flywheel and the starter
it will spin. It's the starter and get a new solenoid too.

Replacing the fuse the first time was the right move, becuase it could have been a fluke that it blew. Replacing it again and again was not! You should have found out EVERYTHING that the #2 fuse controlled and verified that the components weren't pulling excessive amperage (shorted condition). By replacing the fuse over and over, you might have made the problem worse by subjecting good components to something that was shorted.

BTW next time pick the oldest guy at autozone to help you, if the counter help knew their stuff they would have told you the same thing I just did!

I think you are having an intermittent ignition module fault, if its doing it ever few weeks or so then think the main board has a dry joint or a back wire on a plug to it. you would need an auto electrician to have a look. over time it will not do any start engine etc. and by then you would need to replace it. ( the part not the car)

My 2002 ford explorer wont start. lights come on


first thing to check is the battery and the connections at the battery. if all this checks ok then you should try and look at the fuses for the ignition system. this should get you going in the right direction.

Wont start


CHECK SHRADER VALVE ON FUEL RAIL FOR PRESSURE. IT IS COMMON FOR PUMP'S TO GO OUT. YOU CAN HAVE SOMEONE LISTEN TO TANK FOR A BUZZ NOISE ON KEY CYCLES OR TEST FUEL PUMP CONNECTOR HARNESS FOR POWER. TRY KEEPING AT LEAST QUARTER TANK AT ALL TIMES TO KEEP FUEL PUMP COOL,SOME PEOPLE DRIVE ON LOW AQLL TIMES AND KEEPS PUMP HOT CAUSING PREMATURE FAILURE.

1994 ford explorer wont start


Without looking at it sounds like you need a battery. If the battery over 5 years old it needs to go. Once you install the battery it will be well worth it to have someone check the charging system.
