Click on the link.
I tried to get everything on one page, makes it a little small to read. Check for voltage and ground at the starter motor. Any testing make sure tranny is in park or neutral and parking brake is set. Two voltage circuits, one comes from the battery, hot all the time. The other voltage circuit goes hot with key in the crank position and the starter relay energized, goes to starter S terminal. The neutral or clutch switch is also involved in that circuit. Use a test light to check for voltage. The starter motor is grounded through engine block. Make sure battery has a full charge. When you check fuses, also, use a test light and check voltage on fuse circuit, applicable fuses.

SOURCE: 99 Silverado wont crank?

If it was a timing chain problem causing the click and no crank you would not be able to turn motor over manually. I feel it is electrical and state my previous request as the solution thanks. please rate if this was helpful or repost so i can help you further.

SOURCE: 2003 Chevy S10 won't start

Are you sure its the starter? did you try it in neutral? could be park neutral switch, or ignition switch, or if its a standard shift maybe it has a switch on clutch that it has to be depressed to start and its bad. As far as jump starting you cross the maine or big post on starter to small or little post on starter to do that, on a v6 starter it on the right side under exhaust manafold, and i think its on the same side on a 4 cyl.

SOURCE: 01 Silverado Intermittent no start

If new starter and solinoid doesn't do the trick you might check and see if there is an adjustment on the electrial part of the ignition switch down on the colum. I had one causing a problem one time. It was like you just couldn't get the key to turn quite far enough. but a very minor adjustment on the switch worked. It was like there was an expansion or contraction in the switch because when it was warm weather it was fine but cooler didn't want to work as well. This problem was on a 86 Elcamino so things may be different on the 01 Silverado.
I have an 02 Silverado with 50,000 and no problems yet. Hopefully your new starter and solinoid will do the trick because its kind of a pain messing with ignition switch to try that.

It's hard to figure out whats going on with out any codes. Im thinking maybe the fuel pump. To check it after it stops and doe'snt start squirt some starting fluid into the carb and see if it wants to start. If it trys to start then it's a fuel problem.

I have a 87 Chevy Silverado when its Cool it starts up and runs after I Drive it about 2 miles cut it off And try to start it acts like the battery is dead or dying


Your starter and/or starter solenoid are having a typical GM heat failure. Replace the starter and solenoid, check to see that your battery cables and starter cables aren't fried (replace them if they look burnt), then consider placing a heat shield blanket between the engine block and your starter to prevent the issue from recurring.

My 2008 silverado won't start battery is charged


No, it isn't an ignition issue.

Check power to the starter motor solenoid.
If this is getting power when cranking, then the issue is with the starter motor solenoid or starter motor. Replace.

2003 Silverado 1500 HD 6.0 Liter starting issues


I am having the same issues on my Chevy 03 HD 1500. It takes at least two turns of the ignition to get it going. I have replaced the battery, Fuel Filter, Fuel Engine Relay and I am now Replacing the Starter Engine Relay. If you have any other suggestions let me know! I will share as well. Also, last couple of days Oil Pressure Gauge is acting strange. It will read from 1/4 point to 3/4 point while driving. Working on that as well.

1993 chevrolet s10 blazer 4.3l clicks but wont start


Sounds like you have a bad spot on the starter armateur...and will need to replace the starter.

If its the original, and you have over 50K miles then its probably a safe bet that your starter is bad, and will fail totally soon...if thats not the case now.

97 k1500 5.7 liter vortec misses on cylinders 3 and 5 while idling. about 1500 rpm only cylinder 3 and 4 miss then at 2000 rpm only cylinder 4 and 8 miss. what could cause this?


I have had continuous missing issues on my 1997 Silverado after i had a new engine installed 30,000 miles ago. Today I purchased a new gasket for the EGR Valve and removed it. The mechanic had re-used the old gasket when he replaced the engine and cut corners to save $2.00. I found he had installed the EGR bass-ackwards causing my check engine light to stay on and the engine always to miss. Engine runs GREAT now

2000 silverado sometimes start, other times not so much


To determine if recognizing park is the issue simply place vehicle in neutral and attempt to start with your foot firmly on the brake. Starter may have a missing tooth or starter solenoid may have an issue. I would also check ground wire to frame and connections at the starter for fraying or loose connection
