#3026 of 3449 Re: 93 blazer fuel problem , or electrical [repairdog] by chevguy1 Jul 18, 2007 (7:33 pm)
Replying to: repairdog (Jul 18, 2007 2:37 pm) Thanks for the reply. Just tuned up and it is a vortec with the spider injectors. Fuel pump was installed two years ago( Delco) I have another new fuel pump and injectors. If you were to guess where would you go first. Also the injectors were installed two years ago just after the pump a shop. He said they couldn't get new so I got rebuilt. Replies to this message: repairdog (Jul 21, 2007 3:53 am)

Replying to: chevguy1 (Jul 18, 2007 7:33 pm) I would look at the regulaor and lines (nut kit) under teh intake if you haven't been in there as they usually start leaking - any gas smell under hood. Test the fuel pressure.
#3028 of 3449 4x4 Motor/Encoder problem by xpender Aug 03, 2007 (7:51 am)
I have a 98 Jimmy with the 3 buttons on the dash. Everything started last winter when I tried the 4x4. I was at the mall (in 4x4), backed up from the stall, put it in drive and did not have any wheels engagement. The engine was reving, but was not going anywhere. Played with the transmission shifter and got it going again. After that time I tried to use the 4HI and It would not go to 4HI, the light would blink and the 2HI light would come on. No switch appened. I was able to go to 4LO. I replaced the Motor/Encoder. Took it for a spin and the 4HI engaged once. I stopped, put it in neutral tried to switch it back to 2HI and nothing happened. Again the engine was reving without any engagement. I switch it to 4LO in emergency mode. Then I was able to switch it back to 2HI. I checked the vaccuum hoses and they seemed good. Checked the vaccuum switch, and the ball inside was stuck. I replaced it. Took it for a spin. I was driving in 4x4 Hi, stopped at a red light, while waiting I switch it back to 2HI and nothing happened. Tried to go but the truck was not going anywhere. I had to switch it to 4LO the emergency way. Then I was able to switch it to 2HI. Never able to switch in 4HI. The light would blink, and would go back to 2HI. After playing with all 3 switches trying to get the 4HI going, I lost the 4LO too. Now nothing happened in 4HI and 4LO. I can hear the TCCM relays switching, but cannot hear the motor/encoder moving anymore (used to). Is it another motor/encoder that I have to replace? If yes, why did it stopped working after a few hours? Did it burned out? How can I tell? Any help would be appreciated.
#3029 of 3449 Error Code P-0101 by jpmccr Aug 06, 2007 (6:19 am)
Ok, here's the poop. First: 2001 Chevy Blazer LT, 4.3L V6,4X4, with 104,530 miles. My wife is on the way from the airport and she gets a SES light (steady, not blinking). Engine runs but rough. No misfiring or backfires. She stops and calls OnStar and they tell her it is an emission (?) issue and gives her the Error Code P-0101. Did some research on the internet and it looks like it might be a Mass Air Flow Sensor. Am I close?? What is it and is this something I can fix or is this a shop only fix??? Please help . . .

Replying to: jpmccr (Aug 06, 2007 6:19 am) Never mind guys . . . Replaced the MAFS ($115.00) and it runs great now.
#3031 of 3449 Ok one more time by jpmccr Aug 13, 2007 (1:59 pm)
2001 Chevy Blazer LT (104,520 miles)with error code P-0300. OnStar ran a diagonistic and came up with this code. What is it, can I do it, or is this a shop repair????
#3032 of 3449 Re: Key stuck! [draslanson] by c8zz Aug 14, 2007 (4:29 am)
Replying to: draslanson (Jul 09, 2005 12:58 pm) I realize it has been quite some time since you posted this, but I was wondering if you ever found a solution. I have a 2001 Jimmy and my key will not come out at all. It had been sticking intermitantly but last night it stuck for good. So of course this morning I had a dead battery. Any help would be greatly appreciated. Replies to this message: stuntman12 (Sep 05, 2007 8:13 am)
#3033 of 3449 Transmission 98 Blazer by dwbwv Sep 03, 2007 (1:03 pm)
I have trans fluid coming out the transmission vent.Any ideas on what would cause this..I had someone local look at it and they said the seal between the transmission an trasfer is leaking and over filling the transfer case making it back out the vent...

#3034 of 3449 Key stuck release by stuntman12 Sep 05, 2007 (8:13 am)
Replying to: c8zz (Aug 14, 2007 4:29 am) Did you try pushing the release with a key or a screwdriver? There's a little hole on the steering column--I think it's on the bottom (sorry, I haven't done it for a couple years). Stick something in there, push (you might have to fiddle around a bit), and your key should come out. That's how you get the key out when the battery is dead (that's how I know).
#3035 of 3449 Electrical problems on 87 K5 Jimmy by 87k5jimmy Sep 10, 2007 (11:32 am)
I have been over this so many times and can't figure out the problem. when the truck is running it runs great but when I shut it down the battery goes dead. the stereo and dome lights go out alot at the same time but when it is left to sit for awhile i have to jump it then everything works just fine again. PLEASE!!!!! help me I love my Jimmy and don't want to have to sell it. I can't sell it I love it too much. I don't have the money to pay an automotive electrician to figure it out so if anyone can help I would be MUCH ABLIGED!!!!!! I will help you as much as I can on other issues.
