will not start by olehambone

I have a 94 gmc sonoma, v6, manual trans. about 200,000miles. Great truck. A couple weeks ago when starting it would be real slow like the battery was getting weak. Now when I turn the key I get nothing, no click or nothing. Lights work etc. service engine light comes on. So I took battery out and had it checked. It was ok.
Someone said it had to be alternator. I replace alternator, still nothing, no sound or click. Now someone said it must be starter. Where is the starter on this truck and I thought if it was the starter I should hear a clicking sound? What do you think?

starting issue w/99 gmc sonoma by jayoebee

I have a 99 sonoma w/4.3 h.o. It was cranking and finally would catch after 2-3 attempts. I cleaned out the iac motor and the ports and intake sensors. It'll start right up for the first few attempts then it will just crank and not catch at all. Once it is started and running it will start up immediately but if it sits overnite it wont start at all. Any input would be greatly appreciated

Sounds like no power to the ecm, did you check the fuses. Should be an ECM B and ECM 1. Not that familiar with a 86, it does sound like a power problem, short maybe.

I am having a problem close to that same thing. after reading one of the responces on this web site I think I am going to try what they suggested, running a power wire from the battery to the power block on the firewall, the one the courtsy light goes to. It seams to me I heard about this problem a long time ago but had forgoten it. Anyway, Ill give it a try and let you know how it works out. If you decide to try it, let me know how it works for you. GOOD LUCK!!! erg1

1999 S10 Fails to engage the starter after warmup by wtpooh43

My 1999 2.2L S10 fails to engage the starter after the engine warms up. Now slow down, it only happens 2 times ever 30 days. Next, if you leave the key in the "on" position for 3 to 10 minutes, and then turn it to the "start:" position, it will then engage the starter and crank. What is happening?

Check the electrical connections, poor connection are known to be intermittent.

S 10 not starting by erg1

It sounds like your ignition switch is getting worn out.Not the key switch where you put your key in but on the top side of the steering column there is a metal rod that runs out of your key switch down to your ignition switch, which is mounted on slots so it can be adjusted, although I would suggest replacing it if possible, but I know money is tight. Good Luck with it and let me know how it works out for you! erg1

This really sounds like the ignition switch (half way down your steering column, on top) not your key switch! Im sure that will fix your problem. good luck erg1
