| Ok, I have V6 in my 2000gmc sonoma that will not crank when attempting to start. The dash lights up, under the dash clicks(normal sounds) are there, under the fuse box relays click as well but no sound at all coming from solenoid or starter. This happened twice before in recent weeks, after long attempts at jump starting it did start like nothing was wrong, however this third time it will not crank. I replaced the battery, no fix. I really believe its a bad +battery cable, there is more than one wire on the + side so its possible, the one looks bad and I am going to replace it...Also, where is the starter on the v6 4.3.any help at all would be appreciated | |

Replying to: adam6479 (Jan 15, 2008 1:07 pm) My problem only coincidentaly occurred after I had it serviced for an engine light on and poor idling. They checked/"cleaned" the EGR valve (said it may have been sticking open - which you'll read causes poor idle or even failure to start), replaced the fuel filter (said it was extremely clogged). The truck immediately ran great, but the next day I experienced my first "no-start". When we experience the no-start, some of us do two things: 1) keep trying until we eventually wear the battery down, at which point calling for a jump start which somethimes gets the truck going, and thus leads us to mistakenly think its a battery power issue, or 2) keep trying until we flood the engine, which is when you smell raw fuel and it takes anywhere from 1/2 hour to a couple days later when you try to start it and it gets going like no problem. Anyway, I took it back to the shop that week and they checked the fuel pressure (apparently was at 36psi), so a new fuel pump was put in. Then it started running poorly again(maybe the EGR that I did not replace), but the truck started alright for about a week, until this morning. After trying to start it a few times in about 10min span, i finally let it sit for about 25mins, and then attempted again to start it. This time, after two extended attempts she finally wound up and caught - just as the Road Service Guy was pulling up to attempt a jump start. I haven't figured it out yet, but this weekend I'm going to put in a new set of spark plug wires. A few times in the past the spark plug wire change has done the trick when I had poor idle and performance. As it was explained to me, they get crappy over time - especially the cheaper ones - and what happens is they become more prone to taking on moisture. This is why a warm vehicle (or one thats only sat a few hours) starts right up - because the wires are nice and dry and delivering full power spark. You let it sit a couple of days and the suck in the humidity and are cold and you have trouble starting on the first attempt - and then you end up in situation #1 or #2 i described above. I'll let you all know if it works.

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 !!!!!!!

| 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? | |
