2001 s10 2.2 automatic: radiator end cap split and white smoke pouring out from under hood. pulled over in 30 seconds and shut it down. couple hours later replaced radiator and filled it and overflow to capacity. started fine and warmed up to about 165 when steam erupted from drivers side of engine. shut it down, looked for leaks/drips/holes found none. now the engine wont start. whats next?

My mechanic found the problem of why my 1997 Chevy s10 died suddenly while driving it.   He said that the wire going to the ignition switch was rubbing against something and after 9 years of rubbing finally grounded/shorted out the wire.   This must have been going on for 9 years. Probably never inserted properly at the factory. Replies to this message: acrumpler (Jan 04, 2007 7:24 am) vikan (Jan 04, 2007 3:17 pm)

Ok, i have a 2001 Sonoma V6 with 107k on it. For the last couple months i have had a loud clicking sound coming from the engine, pretty sure it is the lifters. I personally have no way to get to them without a shop but i'll keep trying. The problem is this: When i start up cold, i get the clicking and when i accelerate i can redline the oil temp/pressure. At about 3rd gear it'll head back down but every press of the gas will pump it back up. After maybe 5 minutes, sometimes longer, sometimes shorter, the clicking will cease and the pressure stays in the middle of the gauge. I've changed the oil and filter a couple times, i've used thickener and thinner in the oil but nothing has worked. I spoke to a fella at a NAPA shop and he knew of an oil pressure issue with older GMC/Chevy trucks. He says they lowered the oil pressure in these trucks.   Anyone have a similar problem by chance? I'm stumped and i can't believe it would be my oil pump or anything like that. Replies to this message: jpf (Nov 18, 2006 7:59 pm)
#36 of 168 91 S10 4.3 Deceleration trouble by brijar Nov 04, 2006 (9:18 am)
I have a '91 S10 4.3ltr. automatic, 93k miles. This past summer it suddenly started dying as I'd decelerate for a stop. I don't have a tach on the pickup, but it seems the rpms drop too low. It will make a deiseling sound, shimmy and shake, then die. The first time this happened I could not get the pickup restarted. Finally (after many tries), and then after keeping the accelerator on the floor it finally started. I've since not had trouble restarting it, sometimes I have to put the accelerator to the floor, but it always restarts. [On that day I drove it about 8 miles before the trouble started.]   The pickup has had good maintenance. New plugs, wires, fuel filter. After this happened I changed the fuel filter again. That didn't help. I took it to a mechanic and he cleaned the throttle plate and the idle air control valve. He claimed he couldn't get it to die, but it didn't take long for it to die for me. I thought he may be on to something, so I bought a nee idle air control valve and installed it (along with cleaning the area it seats into a little more). That seemed to help for a while, then back it went to the same old die on decel mode. Sometimes I'll just be sitting at a red light and it will decide to start deiseling and try to die.   I've also examined and changed a few of my vacuum hoses, but that has not helped. I tried running a can of Seafoam through it. That seemed to help some, then it got over that and has continued the same symptoms.   I'm suspicious someone could have put something in my gas tank to have started all of this because one of my '04 vehicles started having symptoms a little similar to this at about the same time. I may be a little too paranoid, I don't know. Possibly some bad gas? Wouldn't that have worked itself out by now? I've driven it quite a bit.   I've not had my fuel pressure checked yet. I've wondered it it was safe to disconnect the idle air control valve and see how it runs then. Is that safe?   Any ideas what I should try next?   Thanks,   James Replies to this message: jneal (Nov 04, 2006 12:07 pm) hoodlatch (Nov 04, 2006 3:27 pm)

Replying to: brijar (Nov 04, 2006 9:18 am) I would change the throttle position sensor. That is the most common cause of this sort of problem and is fairly inexpensive. Replies to this message: hoodlatch (Nov 04, 2006 3:27 pm)

Replying to: jneal (Nov 04, 2006 12:07 pm) I had a similar problem on my 92 4.3 a while back. I started replacing sensor with new ones. It started getting expensive guessing which sensor was bad. Instead of forking out 30 - 70 bucks a piece, I started going to the junk yard where they were 5 buck a piece. Then when I found out which one was the culprit I would replace it with a new one.

Replying to: the_goat (Sep 01, 2006 8:33 am) I recently traded in my S10 with 91K miles. It had that clicking noise when cold. Some call it a "piston slapping" problem. I switched motor oil to the 75k oil for high mileage vehicles (10W30). It helped a bit. The best thing to do is not to accelerate too quickly or rev the engine right after start up. Otherwise, I believe there is nothing that can be done short of a tear down of the engine. Good luck.

Replying to: cpl123 (Jul 08, 2006 4:55 am) I am willing to bet that you have your problem fixed by now but I am going through the same problem now. Man it could be anything from a crappy ECM to pressure reg (i have a throttle body) clogged fuel line, filter, plugs, MAF, anything. After you pressure check your system, the pressure should be between 9 and 13 PSI. Since you changed your pump, I would lean to an injector. Best of luck Replies to this message: jrocko (Dec 28, 2006 11:48 am) vikan (Dec 29, 2006 8:16 am)
