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?

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.

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.

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.

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.

96 S10 suddenly dies by smothjazz

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.

I have just recently replaced my intake gaskets, my engine had "puked" mixing the oil and coolant. after i replaced it and alllowed the sealant to sit for over 24hr , i had changed the oil., and drained the radiator.
now.
it wont start. It cranks over has gas, spark, . i cleaned the spark plug holes out ( removed all plugs and turned over a couple of times spitting everything into rags), and allowed to sit for a couple hours b4 placeing new plugs in. i had to turn the rotar on the distributor 180 out cuz it was poofing through the intake, after the 180 out fixed that. but still same situation, the battery is good getting 14-15v has been on a charger most the time to keep it charged.
basically, I have spark, fuel, and no start, i have also tried using starting fluid as well to no avail,was putting smoke out the exhaust a few times while cranking, i am assuming this has no relation to my actual problem. and to top it all off im in the middle of getting ready to move.

Here is my update. It has been about a month since I replaced the wires (one week after the fuel pump replacement), and its been fine since. I strongly recommend anyone having random starting problems to replace the spark plug wires first. Use the best set that the auto store sells, which are usually only in the $20 range. This is one of the least expensive ways to take a first step at solving your starting problem.

When you get #1 TDC on the compression stroke is the rotor pointing to #1 on the distributor cap? How many miles does it have on it.
