#3263 of 3449 Re: Fuel Pump?? [deniced] by johnss10 Sep 04, 2008 (2:14 pm)
Replying to: deniced (Aug 31, 2008 10:40 am) This really sounds like a loose connection. Alternator is 14 volts, battery is 12 volts, so the alternator is going offline when the voltage drops to 12. Could be alternator or battery, or ground. I had a similar situation and it turned out that the hole in the battery for the positive cable bolt was too shallow, so the bolt bottomed out and was not really tight. A washer under the bolt fixed it.

Hi   I am new to the forums and as such don't have much of an idea how it works. I recently bought a 95 GMC Jimmy and have noticed that the truck seems to dart to the left of right when I am driving. There is also quite a bit of play in the steering wheel. I have also noticed that the truck seems to lean to the passenger front side when turn sharp corners. I am wondering if anyone would have a general idea of what could be causing this problem. The truck is in mint condition other than having 314,000 km, but the engine and transmission were re-built at around 170,000 km. I will be taking it into a shop soon, but i don't want to get ripped off, so I though I would ask here first. Thanks, in advance, for your time and help.

Idler arm, tie rod ends, and center link are easy to change. Ball joints, you need to know what you are doing as the springs are involved and care must be taken to compress them safely during the repair.
#3266 of 3449 2000 Blazer4X4 Trouble by kmb6013 Sep 12, 2008 (4:53 am)
Does anyone have any info as to why my 4X4 comes and goes as it pleases? The lights on the dash blink or go out completely and the truck runs like garbage and now the service engine soon light comes on. It feels like the brake is on until it gets into second gear (auto trans). If I manually shift gears it's not as bad, though (again...auto trans). I've been searching for related issues for 4X4 problems but can't find any. I'm trying to diagnose this myself so I don't have to pay a mechanic a couple hundred bucks just to look at it. Any help would be greatly appreciated.

Replying to: mrurl (Feb 01, 2001 12:48 pm) the anti-theft system is full of bugs. there is only one way to fix it and that's by bypassing the system. however, the only way to do that is by having a remote starter put in. i went through the same thing and replaced the ignition and switch but it still happened. after i put the remote starter in i never had the problem again and that was 2 years ago.

Replying to: dbraganza (Sep 10, 2008 7:52 am) Slop in the steering could be a lot of things, as mentioned. Also, if 4WD the axle hubs and wheel bearings may need to be replaced. Thats a lot of miles, and most people don't lube the front end parts very regularly, so a lot of wear is not suprising. I would go to a front end alignment shop first, preferably non-chain, and have them check the alignment, usually $25 or so. Stick around while they do it, and they can show you where the free-play is. Once you know what is needed, then you can get some estimates on repairs. For parts, I've been using Rock Auto, online store, good prices, quick shipping, usually name brand parts. I don't have any vested interest in the store, just good results. Tie rod ends are less than $10, not too tough to do at home, ball joints less than $20 each, much harder to do at home.
#3269 of 3449 Diagonstic by duntov Sep 16, 2008 (3:05 pm)
Unfortunately, most repair shops will charge you a diagontic fee and it may be as much as $90. It may be waived if the shop does the work, but then you must trust them to install the better quality parts and not just charge you for the better parts and install junk parts made of Chineseium. Rock Auto is an excellent source of good quality name brand parts and I use them quite often in my restorations. However, but you must intstall the Rock Auto parts yourself. If there is a job above my pay grade, I have a younger gauy I found on Craigs List who will install my parts while i watch. I pay him $40 per hour and I still come out cheaper than taking it to a crooked repair shop. I would estimate that 85% of the auto repair shops are crooks. That is the only way they can make a decent profit.

I have a 99 blazer 4x4 that I put in 4 low and the light on the dash just kept blinking, althought the vehicle felt like it was in low I don't believe the front was working. I then put it in 4 high and the light wouldn'tstop flashing also. when I put it back in 2 high all was wll. I tried this a couple of times and had the same result. Whaddaya think?

Replying to: chevguy1 (Sep 21, 2008 5:24 am) Your Blazer needs vacuum pressure from the manifold to shift into 4wd. So I'd start by checking the vacuum lines from the manifold.

Replying to: toleson (Dec 15, 2007 11:17 pm) I would change the dimmer/headlight switch. i had no dash lights only my aftermarket radio.
