Question about 2000 Chevrolet S-10

4 Answers

S-10 won't start

Charged battery. lights and warnings, radio work when you turn the key. truck wont start. Tried it in neutral and tried it in park. Thought if I rolled it forward or backwards a little and tried it again it may help, no luck. When I turn the key it makes a snap sound followed by a shhhhhh sound. without turning the key to off if I try it again it just makes the snap sound the second time. It doesn't make any clicking noises or any other noise other than the single snap sound.

The snap sound is the solanoid on the starter. you need to look at the starter and see if the big red wire correded off the starter. also check the ground wire going to the front of the engine as they also like to corrode/loose connection. check your battery voltage at the battery and at the starter on the big red wire.check these while cranking the engine with some help from a friend. if all these look ok then you probably just need a starter.
good luck

My Answer:

Being a Degreed expert in this Electronics field this should be fairly easy. See my professional references posted at the end.

First of all - It appears (notice I say appears) that your charging system is functioning OK if you did the QUICKIE alternator/regulator test and that part appears to be fine. Did you?

Next - Never ASSUME you have a good, fully charged, or even a NEW battery whatever the case may be. I've seen brand new batts fail a few months after purchase for no known reason at all. Water level should be topped off esp during Hotter weather as water level will drop as the batt ages.

AND - when in doubt - Always do a hydrometer test on each cell, and make sure all cells read equally at approx 1.285 to 1.290 - indicating a fully charged batt.

Next - do a batt LOAD TEST.

When doing a LOAD TEST with an external 100 Amp Load Tester make sure you disconnect the POS terminal cable (or better yet both batt cables) on the batt before doing a good Load Test on a "supposed" fully charged batt.

Batt voltage on a good fully charged batt should never drop much below 11.4 to 11.7 volts doing a 10 second load test using a 100 Amp Load Tester similar to say one bought at Harbor Freight Tools for like $15 when they are on sale. If the voltage drops below 11.4 volts, or even say 10 volts - then your batt is NO GOOD. That is - if it indeed is FULLY charged??

If the top of the batt is wet (for whatever reason such as dew-point or leaky batt acid) this will cause the batt to self-discharge right across the top of the batt. Just like putting a small light-bulb across the batt posts and causing a drain. It happens more times than you care to know. When I worked at SEARS I seen it day in and day out......trust me I know this for FACT!

If the batt posts are very very dirty then that very possibly is your problem right there (you'll need to remove both cable clamps, and clean both the clamps and the batt posts until the lead is nice and shiny and then re-tighten again!).

If your batt is being run down for any reason you'll need to do a few more checks below:

Next - you'll want to check for a couple things at night, or else daylight will work as well - if you have good eyesight. You want to check and make sure your "backup lights" aren't ON when the Headlights Switch is turned OFF and the Ignition Switch is OFF as well. Sometimes a SHORTED Transmission Backup Light Switch will cause a battery drain with everything shut off. Sometimes!

Also - If you have any Interior Lights left on when the SUV doors are all closed that will surely drain the battery down.

A radio/stereo left ON will do the same as well.

A shorted tail-light (or any marker light) will also cause a battery to drain over time.

Any vehicles that have an under the hood light Mercury Tilt Switch for the Engine compartment sometimes can have this switch mounting come loose and when you shut the hood the light will actually stay lit thus draining the batt down as well. Make sure you check it at NIGHT during darkness as it will show up better.

If any of the above proves indeed to be a batt drain related problem, then we nest need to isolate the related problem.

In which case you will have to do an actual DVM in-line amp meter test to see just how much current leakage (shorting) you have. A fuse block isolation test will next have to be done to isolate from which circuit leg the short (or current drain) is coming from.

Once that circuit is isolated then it's just a matter of finding the shorted device or shorted wire(s).

If you just added anything new electrical wise to the Jeep recently- then that is a good starting point - for if the problem wasn't there before that time, and now it is - then there is your culprit!

If you are using an external battery charging PV (Photo-voltaic) panel, and it's bad for any reason - then it will drain your battery down as well, esp if the blocking or back diode goes bad.

Also - If you have a dual battery system with a BATTERY ISOLATOR installed you might want to double check all your wiring there as well - as I've seen them go bad and cause many a battery problem!

Having said that above -

Some Ford models also have/had a dual SOLENOID system with one being right near the batt, and the other one (normally) mounted on the starter.

Both solenoids will need to be checked in that case, as the starter solenoid might be good but the "ignition" solenoid might be bad - as to having bad LOAD contacts inside or else loose Batt +12 volt cables!! Cables can get loose or else go bad at the crimped lug ends!

It's rare that the starter itself or the starter solenoid has a bad ground, as then the solenoid mounting bolts or starter mounting bolts would have to be pretty darn loose. It happens but not that often. Usually the flywheel will make a GRINDING sound first and that is a BIG indication something is terribly WRONG there!!

If all the above proves NOT to be the apparent cause, or seemingly not related to the starter problem itself, then very well the starter brushes are shot - as in worn out! At which point a replacement starter is needed. Providing this is the OLD starter indeed, and not a rebuilt one to begin with that just has been replaced recently. Is it the original, or OLD starter?

If so and if it's had over 100-150,000 miles on it - chances are it's SHOT.

It's gotta be something I just went over here - as I covered everything......

Let me know what it was OK? Post a reply here and please rate my troubleshooting fix.

Thx,

Frank

Try replacing the fuel sending unit first. Then check your ignition relays. Are you ruining any codes. because for the most part your truck will tell you whats wrong if your pump is bad it should run a low fuel pressure code and if there is something with the ignition you might run a oxygen sensor code. when you turn it over do you smell gas.

Sounds like starter motor given your slow to no turnover, I assume your new battery has full charge, if not, check with meter, it may be a defective battery, or another issue with connections, did you clean cable connections when you put in new battery? I assume your engine was running properly before battery change and is not partially seized due to overheating or low oil.

Good luck,
