#322 of 364 S-10 2.2 wont start after chainging timing chain by kthompson2 Feb 24, 2009 (11:37 am)
Timing Chain and tensioner broke on my 1995 S-10 2.2 had the timing chain replaced and now the truck will not start. I checked to make sure the timing chain was lined up right but still will not start. Replies to this message: mickeymouse2 (Feb 24, 2009 3:48 pm)

Replying to: kthompson2 (Feb 24, 2009 11:37 am) If all that checks out and the engine cranks but still doesn't start, check the compression. Valves may have got bent when the chain broke. Minimum compression is 100 psi on each cyclinder.

It all started at a stop lite. The service eng lite came on, started to miss and then died. It started up but was running real rough. Checked codes and said bad egr. Changed the egr, cpi unit as it was leaking, new ac plugs, wires, coil, cap, rotor. It runs great at an idle or when your rev it up, but when you put it in reverse or drive it starts to run rough. Take it out of drive and it runs smooth. fuel pressure is good. Need help. Replies to this message: egummer (Apr 10, 2009 10:17 pm)
#325 of 364 2000 SONOMA won't start when cold outside by darb324 Mar 03, 2009 (6:45 pm)
Having trouble getting my 2000 Sonoma with a 4.3L V6 to start on cold mornings when its around 20 degrees or less. The engine turns over but doesn't seem to fire at all. Not sure if its an electrical/ignition problem or a fuel delivery problem. The fuel pump runs when the key is turned on but am not sure if I should eliminate that as a possibility? It starts and runs fine when the temp outside is above freezing. Any suggestions or ideas would be appreciated.
#326 of 364 94 S-10, many issues by ralvey Mar 05, 2009 (6:25 pm)
Hey guys i have a 1994 chevy s-10 LS extended cab with the CPI 4.3 and select trac 4X4 system. i have many issues with this truck that i need help/advice with. 1. How hard is it to replace/rebuild the CPI system, what do i need other than the spider injection kit? 2. Where can i get a new cable for my 4X4 system(from the shift lever to transfercase) 3. both my windshield washer and intermittent wiper settings have gone. the wipers only run on the "high" setting. they both went at the same time so would that be the switch that has become inoperable?(cruise control still works...) 4. How hard is it to replace the antennae cable as mine was burned apart due to the exhaust manifold. Any help would be greatly appreciated as i need to fix this vehicle asap for my summer work. Ross
#327 of 364 2001 S-10 Over Reving by freddy0872 Mar 08, 2009 (2:04 pm)
Greetings! My dads 2001 S10 decided to take a mind of its own the other day. All of a sudden out of the blue it started to REV VERY HIGH! I can pretty much put the truck in first gear take my foot off the clutch and hold the brake and it wont stall out. I get three codes when I plug my reader into it. I get P0137 which is on O2 sensor and that is because he has an exhaust leak. I also get P0453 with is the EVAP and i also get P0507 which is Idle air controll system RPM higher than expected. Now between 507 & 453 i get lead back to the EVAP. Is this my problem? can anyone help me out please! We reciently changed out the fuel pump on it. and did plugs and wires. Thats about it. And help is appreciated!   Thanks in advance   Fred S.

Replying to: acobbold (Feb 23, 2009 4:28 pm) update From message #321, after all was said and done, I changed the actuator valve, the mechanic said that there was moisture in the air line and when it is cold the truck is in 2x4 even in 4x4 after it was fixed !      I then had to fix front Premium wheel bearings , after pricing 3 different suppliers Canadian Tire was the cheapest except for eBay, which by the way if you order O2 sensors off eBay make sure to ask if they are OEM, one's I bought had to be tampered with in order to fit properly, and no recourse because of the mistake, ask more questions...  all in all I forked out $686.00, truck runs perfect now YEH!!!!
#329 of 364 Re: What hose is this, how do I order [electech] by 92s10blazer Mar 27, 2009 (7:19 am)
Replying to: electech (Feb 17, 2008 9:56 am) Hi,          I have a 92 4.3 TBI.... If it's the same hose as i had leaking then broke when i tried to remove it, then i went to hardware store and bought a fitting w/ a nipple and spliced it in. by the way i had to use an easy out/reverse drill bit to get the old zinc type fitting out of the manifold. Mine was a quick connect fitting hose too... Hope that helps.                             -Eric

Replying to: retiredflyguy (Feb 28, 2009 6:28 pm) Check into the cadilidace converter.(sorry for spelling weakness).I've had same thing happen and it was a blockage in the exhast.when engine has no presure from trans it can expel the exhast easier but when it is drivin it builds up and bleeds back into the engine causing it to run like crap,draging an anchor,lack of power.
