#3353 of 3449 Re: gear shift indicator light flashes with turns signals [Mr_Shiftright] by pvanman Mar 28, 2009 (1:15 pm)
Replying to: Mr_Shiftright (Mar 26, 2009 6:34 pm) Mr. Shiftright, took your advice, bought another flasher this time at NAPA, and, bingo! Turn signals work and the shifter light is back to working normally. The place I bought the original flasher the guy at the counter didn't speak English too well and I think we had a breakdown in communication. Lesson learned.   Thanks again for your advice.
#3354 of 3449 Removing starter motor in 1995 Chevy Blazer 4WD 6 cylinder by chevyride22 Mar 31, 2009 (9:45 am)
What is the easiest and best way to remove a starter motor from a 1995 Chevy Blazer 4WD 6 cylinder? Should I remove the connections first? I tried removing the connections from the starter by going through the wheel well. I also tried dropping the starter to get to the connections, but could not get the starter to come out. Do I need to take the flywheel cover off, or should I be able to get the starter out without removing the cover? The flywheel cover bolts are very tight (cannot loosen even with air tools). Please advise on how to take starter motor out. Thanks. Replies to this message: Mr_Shiftright (Mar 31, 2009 10:17 am)

#3356 of 3449 fuel gauge bounce and high speed hesitations by demonhide Apr 01, 2009 (4:10 am)
I read a lot about fuel gauge bouncing, some say possible grounding issues on sending unit. The bouncing needle works fine till half tank then stays there. When i first start the truck it will slowly go to roughly the right spot then bounce up and down. Once I start moving it goes to half a tank and stay there. The whole thing is kind of annoying at best, but can be dealt with. I guess I should state this is a 99 Jimmy with about 130k miles. I have nearly replaced the entire front end ( ball joints, a frame, bearings and hub) Last thing I had to replace was muffler system to cold power loss. But the most important thing I want to fix is the high speed power hiccups. I do 150 miles a day on interstate. Low speeds this vechile is very powerful, But at 70 mph, I am getting this random hesitation or power hiccup. It is rather hard to explain as it is hard to realize unless you push the truck, but if you push it to far it will just shift down and go like a bat of hell. Any ideas what i can look at? Thanks in advance Replies to this message: johnss10 (Apr 21, 2009 4:08 pm)
#3357 of 3449 lean by 20blazer00 Apr 20, 2009 (4:22 pm)
I have a question for you all. I have just noticed that my blazer leans on the driver's side( or its somehow lower on that side). Now is this common for blazers? I just happened to look at the parking lot at work which is flat and level, but my blazer was sloping on the drivers' side.    2000 Blazer LS 4x4 Replies to this message: johnss10 (Apr 21, 2009 3:00 pm)

Replying to: 20blazer00 (Apr 20, 2009 4:22 pm) This is not uncommon in 4X4's they use torsion bars in the front suspension, since the front drive axle's go through where the coil springs would be. There is a ride height setting procedure in the Haynes or Chilton repair manual. Also, a front end shup will do this as part of the alignment. The alignment may well be out as well, so probably best to take it to an independent, locally-owned shop.
#3359 of 3449 Re: fuel gauge bounce and high speed hesitations [demonhide] by johnss10 Apr 21, 2009 (4:08 pm)
Replying to: demonhide (Apr 01, 2009 4:10 am) These two things might be related. The high speed miss could be a weak fuel pump or clogged fuel filter. Cheapest/easiest is the fuel filter.   The gauge is either a poor connection, or more likely a worn float assembly. The float assembly and fuel pump come together for these vehicles, so replacing the fuel pump/fuel sender may fix both problems. About $130 for the parts. I'd check with Rock Auto on the net first, ususlly have best prices.
#3360 of 3449 96 gmc jimmy blowing fuses..... by victor60 Apr 25, 2009 (9:18 am)
My 96 GMC Jimmy keeps blowing the #9 fuse. which control the fuel pump, fuel control relay sensor, the ecm. All of these have been changed and yet it still blows the fuse. Stopping the engine from running. After they were changed it started but when i put it in reverse it shut off. And blow it again. Now when i put the key in the position it blows the fuse.
#3361 of 3449 Blowing fuses by 20blazer00 Apr 26, 2009 (3:35 pm)
To me that sounds as if you either have a short or a bare wire exposed.Maybe in the fuel system, like between the tank and body. I'd guess that when you put it in gear it viberates and shorts out or maybe just cranking it causes enough to short the wire(s) out. I'd have to start there, and run down the wires until you find it.
#3362 of 3449 Fuel pump wiring harness by duntov Apr 27, 2009 (2:48 am)
Whenever the fuel pump is replaced, it is recommended to replace the fuel pump wiring harness and the screem. The wiring harness and screen usually does not come with the fuel pump and must be purchased separately.
