#68 of 195 1995 Chevy S-10 Major Problem by gettin_lefty Jan 18, 2008 (3:01 pm)
History of problem Two weeks ago my service engine light started flashing at a rapid pace. The engine started acting like it was fuel starved or not getting proper spark. I managed to limp home by taking automatic out of gear at stop lights and keeping foot on gas to keep revs up. When I got home I turned engine off -tried to restart--would not start-would crank but NO start.   Had it towed to local garage-they said their code scanner could not get ECM box to work or could not get codes. Replace ECM box with new one-still same thing. Checked fuel pressure-OK-checked spark to plugs -OK-checkd voltage to injectors-not ok no voltage at all.   Have tried everything--this 4.3 V6 does not have a crankshaft sensor --has distributor--does anyone have any idea at all what the problem is???   thanking all in advance Mike   http://theconservativearmyforumreview.podomatic.com/

I have a 2000 S-10 , 4.3l. 135000mi. Bought this truck new, about 3 years ago it wouldnt start. Turn the key and just a click. Thought it was a bad battery, replaced it and still no start. All the dash lights worked, normal buzzers and sounds, but when you turn the key you just get a click. Starter never even tried to engage. Took it to my mechanic and he said it was a small wire that was loose, and it started fine from then on. He never showed me this wire. Well now its doing this again. Again, I replaced the battery, also have replaced the starter. The fuel pump was replaced 14 months ago. My old mechanic is gone now, so I cant ask him. The local repair shop says he is finding nothing wrong, and no computer codes showing anything. HELP !!!!!!! Replies to this message: mc22x3 (Oct 31, 2009 3:13 pm)

Replying to: nitrate (Oct 10, 2007 4:32 pm) I FINALLY SOLVED MY SAME EXACT PROBLEM. I had someone look at the coil at night while I started the engine. He noticed an arching at the coil. Upon removal of the coil I found white electrical burning marks at the coil frame on the side. Replaced coil and every thing fine now. On moist days the coil would short to its frame. As the engine heated up the moisture path would evaporate and them would run fine. HYope this helps.

I have a 2000 gmc sonoma pick up. At times it will not start. I get absolutly nothing. No click, no lights, no sounds, nothing. It won't start with a jump, still nothing. I have a new battery and starter. But, if I disconnect the positive battery cable from the battery and then reconnect it, it stars right up everytime. Any ideas?

Replying to: mspinder (Feb 12, 2008 7:54 pm) When you have a no start, check with a 12 volt test light to see where you have lost it. A test light is better than DVOM, it puts a load on the circuit. Check the battery cables for corrosion, could be a bad positive cable. Replies to this message: mspinder (Feb 13, 2008 6:55 pm)

Replying to: gonogo (Feb 13, 2008 9:29 am) Thanks for the quick reply. When I have no start there is no juice coming to the battery. The minute I disconnect the positive cable and reconnect it I have juice and the truck starts right up. Battery cables are clean and free from corosion.

Replying to: mspinder (Feb 12, 2008 7:54 pm) Is your key the type that has the security chip on it. I just had a go around with the same symptoms your having with another GM that turned out to be the key chip. Replies to this message: mspinder (Feb 16, 2008 2:37 pm)

Replying to: hoodlatch (Feb 14, 2008 8:41 pm) The truck does not have a rermote door opener. Believe me this is really strange. No power at all, then, disconnect the hot battery cable and reconnect it and it stars with no trouble at all, all kinds of juice.
#77 of 195 96 S10 suddenly dies by smothjazz Feb 17, 2008 (1:57 pm)
I hope one of you gearheads out there can help me. My 2.2l w/auto 96 S10 with 280K will suddenly die on me. I was traveling at about 100K per hour when it was like someone turned the key off. The speedo went to 0, and I could hear the relays in the glove box ticking away. I coasted to a stop, and I could hear the relays clicking. The speedo seems to be jumping at about the same rate. By process of elimination, it was the most left relay that was clicking. The check engine light also flickered on and off. Turned the key off and on a few times, and the clicking continued. Turned it off for 10 mins, no clicking , tried to start, and it ran as if nothing was wrong. No check engine light. Very interminit, sometimes twice a day, sometimes nothing for 2 weeks. Seems to be better when weather is cold. No change if tank is near full or near empty. Sometimes the truck will not start if sitting for a few hours, but will go after a few hours. Have had it in the shop several times, but no luck. Don't know if it's related, but I have an ABS light on. Could this issue be caused by an ABS speed sensor? Does this truck have a speed sensor? Thanks in advance for any help you guys can give. I'm happy my wife isn't pregnet and we had to depend on this truck.
