Question about 2002 Chevrolet TrailBlazer

Diagnosing starter or celinoid problem...or short

2002. will start fine 3-4 times, then nothing. not battery. how do I tell if it is the starter or celenoid or something else. the starter makes no noise. putting a screwdriver across celenoid will not engage starter or start vehicle. seems to new to be starter but it does have 100,000 miles. I need to determine cause and order parts to have a shade tree mechanic do work. no choice due to money. it does not seem as if it is an engine problem, but i was wondering about possible short? back glass is out and I have to manually push on backside of locking mechanism or it does weird things. sorry...I am a woman with limited mechanic speak! teressa

    THANKS for the suggestion. I def will try this as strangely, when I put it on a charger, it still wont start, but when I swithced charger to rapid charge, I got it to start sunday. wish I hadnt as it started just fine for first 3 times and then stranded me 30 miles from home with my 88 y/o mom!

    I had to call towtruck. they are ones who thought it was for sure starter, but the cables are not great. it is a brand new battery. I will try this

    j_jayhoon,



    when you say replace cables. where do they originate at opposite end from battery? sounds stupid I know, but was wondering? I am going to ask my neighbor to pick me up some when they go to town and need to know exactly as they are even more car ignorant than I am.

    whfen you say check the fuse panel and look ..."position" of starter relay, what position do I want it to be in, and what does it look like? I only know about fuses in the panel...are there other items in the actual fuse panel? you arent talkng about the fuse panel under the dash I take it. I will look under the hood and see if I can spot another fuse pane is it just for the starter relay? .1st, I will change the battery cables like was suggested...and pray that is what it is!



    I may not be mechanical but am determined and resourceful! if I can find a book telling me how to do this, then I am good! thanks you all, teressa

May be starter relay this will be under the hood check the fuse panel under the hood and look for the position of the starter relay. change this it is cheap and see if that helps. and your sure your battery is fully charged when there is no activity because it will not engage if not enough juice. start at the relay though and well move on from there.

    relay would be against the firewall which is what divides the driving compartment and the engine. it would be a small square looking device with wires coming out of the bottom side of it. the fuse panel under the hood may also contain this relay. check your manual. if you dont have one, GET one because they are a wealth of information and can save you thousands of dollars in the long run.

IGNITION STARTING PROBLEM


If the starter is turning there is no need to try to short past the solenoid. It shouldn't harm the computer to do so, but all that does is make the starter turn, which it is apparently doing anyway.

First of all, common sense tells you, that you didn't need 6 sensors

Codes do not tell you to replace anything
Study OBD2 Systems

I have a problem when someone say for a long time

I assume that means up to six months

If your not a car person capable of diagnosing &
make at least some repairs,then you need a repair
shop ,after a couple of weeks,at least for some issues

Either study cars & obd2 or pay a shop while your learning

the remote starter is not going to damage the starter, but if wired wrong it could damage the wiring or fuses, or run the battery down from a short.

After disconnecting the battery, check your ground wire connections and your positive cable connections to starter. They could be coroded and loose. I believe their is a celinoid relay after the battery make shure that is clicking if not replace if needed.

Starting problem, starter doesn't enguage. good starter, battery, celinoid, ignition lock, flex plate.


Have you chk. the starter switch on the steering colume under dash? Or is starter drive kicking in but not engaging teeth in flexplate? If its not engaging teeth on flexplate starter needs to be shimmed, or if its missing the teeth altogether on flexplate or bearly catching the teeth, top of starter nose wear it bolts up needs to be filed down to engage the teeth on flexplate.

bad ground wire on battery,if everything dims in vehical while turning ignition and I mean from bright to almost nothing thats what is wrong,if not some have a small fusible link to solenoid that blows or gets disconnected or corroded.
your ground wire will look fine but maybe have broke or corroded connection inside or on ends,had same problem with more than one vehical.easy check use a jumper cable from negative on battery to alternator bracket and give it a whirl.
