#672 of 1497 Re: My '99 5.7 has a security system glitch.. [jjuarez] by chevyss Sep 21, 2005 (2:34 pm)
Replying to: jjuarez (Sep 17, 2005 4:53 pm) Yes, I have a fix, and if you are a little handy you can fix it for good, for almost no cost!!   It is most likely a bad resistor wire in the ignition key circuit. I had same problem. Every once in a while, my '98 Sily would not start. Drove me nuts. I noticed my "security" light coming on every once in a while while I was driving.   Anyway, after getting stuck enough times, I finally got ambitious and did the permanent bypass trick on the security wire. I found some instructions on the web. I cut the yellow wire, then measured the cranking ohms resistance at 577. Then off to Radio Shack, where they had 560 ohm resistors +/- 5%. I bought a pack of five for 99 cents. I measured the resistors to find the best one. Closest I could get (to 577) was 554 ohms, so I soldered that one onto the yellow wire (processer end) and into the orange/brown wire. Total cost for parts; about $2, yeah baby!   The instructions said I needed to be within 1% to 2% on the ohms. I was more like 4% off the 577, but the truck fired right up with no problem.   This trick permanently bypasses those tiny little wires that go to the cylinder lock. Still working perfectly (after eight months). Plus, I went to see a buddy of mine who works with electronics and he built me a 576 ohm resistor using three in series. Someday I might install my new resistor which is almost exactly the measured cranking resistance.   Look on the web and you can find instructions, I forgot the link I used or I'd post it for you. Just make sure the instructions are applicable to your vehicle.   This should fix you right up.

Replying to: junster (Jul 26, 2005 4:39 am) 2 problems, 2 solutions.   For compressor problems, check to see if system was properly flushed and exp valve replaced during last compressor changeout. To prevent springtime startup failure, run air periodically during winter to keep system lubed and sealed.   For low air flow on Max AC setting, check recirc intake above front passenger footwell for debris (like a plastic bag) thay could be partially blocking or sucked into intake.

Replying to: tenaha1 (Jul 16, 2005 2:29 pm) I have a 1995 Silverado HD 2500 extended cab 6.5 turbo diesel that the engine dies while driving down the road. I have replaced several switches related to the fuel system to correct an on going problem. It started dying again and now the dealership says it is the fuel injection pump which was covered under a special policy untill 120,000 miles or 11 years, whichever came first. I have 141,000 miles on the truck and they want 2,000 dollars to fix it. I am trying to negotiate some relief in this repair. So far they have denied my requests. Did you find a solution to your problem? Replies to this message: jjtj (Sep 23, 2005 4:20 am) park11 (Oct 07, 2005 8:30 am) gmcrooks (Oct 16, 2005 9:29 am) gmcrooks (Oct 16, 2005 9:44 am)

Replying to: mel18 (Sep 22, 2005 11:08 am) These engines are known for this exact problem.. it could possibly be just the PMD unit. It's a small electronic box that sits next to the injection pump on top of the intake. For whatever reason, GM placed it right where it's going to pickup alot of heat. Over time, the heating/cooling effect kills this box. It's basically the computer control for the injection pump. You can pick up a new PMD on ebay for not a whole lot of money.. you'll even find many people offering the new PMD on a remote mount with a heat sink where you can mount the PMD away from the engine which solves the heat problem. It's a plug in installation & is very simple. Not saying it's not the pump, but I know many dealers jump the gun & say it's the pump when it may only be the PMD. Here's a link to what I'm referring to:   link title Replies to this message: park11 (Oct 07, 2005 8:30 am)

Replying to: iluvmytruck (Aug 17, 2005 12:58 pm) I have a 2003 Silverado and the tailgate falls going down the road also. Do you have a spray in bedliner? I wa s also wondering if there was a recall on this issue.

#679 of 1497 2000 Silverrado 1500 hard to start when warm by bykehoun Sep 24, 2005 (7:29 am)
My truck has a 5.3 engine that starts perfect when cold but you have to pump the accelerator or hold it down to start when hot. Is there a sensor or something that I can replace? Can't afford the shop prices. THANKS!
#680 of 1497 BYKE by ryanbab Sep 24, 2005 (10:52 am)
Do you have a starting problem like if you drive to a store park for 25 min to 1 hr and then its hard to start? Try checking your fuel pressure regulator. Pull the vacuum tube off after driving a bit. If you get gas out of the tube then your FPR is bad. $40 part and 10 min to change. I just had this problem on my 00 with 55K miles Replies to this message: bykehoun (Sep 25, 2005 6:29 am)
#681 of 1497 slow or disfunctional windows by chevymann Sep 24, 2005 (12:25 pm)
Hello, I own a 99 chevy silverado, and some times my windows go up really slow, even stop some times.. The other day I rolled my window down, and it would not go back up. I drove all the way to work with it down, and then on the way home from work, I was just messing with the switch and it went up. I am half afraid to roll it down now!!! Anyone have any ideas????
