#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.

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.

Replying to: kegger117 (Jan 18, 2008 9:08 am) 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.

Replying to: bankai247 (Feb 21, 2008 6:07 am) 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.
#81 of 195 no juice, juice by mspinder Feb 22, 2008 (3:07 pm)
I thought this would be something kind of easy. There is no response at all, nothing, no click, no lights no juice to the battery, nothing. Then, disconnect the positive battery cable from the battery and reconnect it and like magic it starts right up. It does not do this all the time and with no particular pattern. I can't have the only Sonoma that this has ever happened to?
#82 of 195 out of ideas please help! by rdracing14 Feb 24, 2008 (12:34 pm)
I am having trouble with my 97 GMC sonoma 4.3L V6. It is not getting any fire to the coil. I have replaced the coil, distributor, cap, button, pickup, plugs and wires, crank sensor, coolant temp sensor, and swapped out computer. Still no fire but it will turn over. Battery is good. Friend of mine hooked it up to a computer and its not reading any codes! What the heck can the problem be. I would really appreciate any advice because I am out of ideas! Oh and by the way when the truck broke down it backfired and blew out the top of a flowmaster!!!    Thanks in advance for any advise! Replies to this message: gonogo (Feb 25, 2008 8:49 am)
