#181 of 444 99 s-10 Starting issues
Mar 07, 2008 (6:45 am)
I've replace the starter twice on my 99 S-10 2.2 5-speed, 132,000 miles. This time I replaced the starter and flywheel. F'wheel had a broken tooth. It still acts strange. The engine tries to "kick back" when cranking. Reminds me of a wet distributor cap from years ago. I removed the ECM fuse and it cranks fine, so I'm pretty sure it's ignition related. Once it starts, it runs perfect, no check engine light, no codes. Someone suggested replacing the crank sensor and the cam sensor. I did, no change. I'm know I'm going to ruin another starter and flywheel if I don't solve the problem. Has anyone heard of this problem before? I do have new plugs and wires on it, but I've never replace any coils.

I reread your first post, you have quite a mess there. Little history, did this just happen all of a sudden or was there work done or was it jumped.
You say no head lights, I would start there first, with every thing off the head lights will come with the switch. Unplug one of the head lights, with switch on should be power there, I like to use a 12 volt test light in a situation like this.

Well, I took a chance a bought a couple of coil packs and installed them. That fixed the problem!! I hope this post may help someone in the future with the same troubles.

I will check the power to the headlights today. however I'm thinking there will be no power since the headlights do not come on (with the headlight switch on, the parking lights come on).
So, here's what happened that day...I drove the car to work and everything was fine. I went back out after work and the car seemed to start normal, however I noticed the headlights were not on and the brights icon was on in the dash. I didn't really think anything of it until I hit the brakes and the engine died.
The only work that has been done recently (aside from oil changes) is a starter replaced about a month ago and the alternator around 6 months ago. I did jump my sisters car a few weeks ago (not sure exact date).

Have you had it checked for codes? You could still have power to the head lights and they will not come on without a ground.
I own a 99 Sonoma 2.2 auto. I have lots of information on the 99, the head light schematic looks like a bowl of spaghetti.
The 99 also has a BCM, Body Control Module, not sure if that could cause your problem.

No engine codes. I have the Chilton repair manual which has several wiring diagrams that I've been looking over. It almost looks like there's 2 seperate issues, the lighting and the heater. I'll check back once I look at the power to the lights...
#187 of 444 Do i have a short, bad voltage regulator or something else ?
Mar 12, 2008 (5:41 pm)
this is the first time posting on this forums and only because i'm about to loose my job because my truck is making troubles.
I bought a 83 s-10 (2.8l v6)from a car shop last week. when i testdrove it everything except the headlights worked fine. they said they're gonna fix it and i can pick it up at night. when i came to pick it up i had to compression start the car but the headlights worked. i drove for 5 minutes and the lights started getting dimmer and the turnsignals stopped working.I pulled into a gas station, turned off the car, turned it back on and it worked fine again. 15 miles later the voltage dropped all the way down and the engine died. My buddy came with another batterie and i could drive it to my house. The next day i drove it all day (never used the headlights) but at night and probably 20 minutes after i turned on the headlights the voltage started dropping again and i turned the car off before it could die again. Then nothing worked anymore, not even a click to start it.
Next morning it started without any problem and again ran all day. even had it running with the headlights on for a while and it worked fine. then again at night i had the same problem and i turned the car off(had to jumpstart it the next day).
Autozone tested alternator and it was fine...
the wiring seems kinda screwed up so i wonder if i could have a short
any helpfull tip is much appreciated !
thx in advance
#188 of 444 Requesting Electrical Diagrams for A/C Heater
Mar 24, 2008 (1:02 pm)
I've a 95 S-10 2.2l, and I'm trying to work on fixing my heater/a/c issue, and I believe that it is a grounding issue, but I'm unaware of where the grounds are for this.
So if any of you have or know where I could get them, I would be much, and greatly appreciated.
#189 of 444 All turn signals come on at the same time...
Apr 13, 2008 (1:22 pm)
I have a 1985 GMC S15. When the lever is right, or left all of my turn signals come on at the same time. Would there be any help out there for what the problem may be?
