#3440 of 3449 Fuel Pressure Regulator by 00blazer1 Oct 20, 2009 (6:16 am)
I have a 2000 s-10 style blazer and have problems starting with out shooting throttle body cleaner into it. Fuel pressure is low. we've come to the conclusion that its the pressure regulator. Can someone please link or tell me how to change it? I have the part but not sure if there is something I need to know about changing one beffore I get into it. Thanks in advance

Replying to: sticky23 (Oct 19, 2009 8:55 pm) Depending upon the mileage, you could have a bad throttle position sensor. Fancy name for a little device that tells the computer how far down you are pushing the throttle. When bad, these can do everything from screw up the idle to causing stumbles during throttle transitions to the symptom you described.   And yes, you do have multiport fuel injection. What you are seeing that looks like a throttle body injection is just the "air valve" to the engine. The injectors are not visible from the outside.
#3442 of 3449 Re: 2000 Blazer Electrical Problem [rafike32] by tim153 Oct 21, 2009 (8:56 pm)
Replying to: rafike32 (Aug 24, 2006 8:57 am) I am having the same problems. 98 Jimmy that starts and drives but many electric items are not working. Head lights will not come on, but high beams work, No radio, heater, outside temp is not working. NO inside lights, 2WD/4WD lights are not on, and no tach, speed, mile indicator.   This is strange any ideas where to start? I though it was the wire harness going from the fire wall to the keyed switch so i changed that and it did not help.

Any one have an idea on how to lube the cable assy. that holds the spare up under the blazer? Glad I was home in the driveway when I tried to lower it and not out on the road someplace, had to use by biggest screw driver and 12" cresent wrench to get it started down, after about 3" all was fine but I would rather not try my luck when I need to use the spair.

Replying to: bluejay5 (Oct 27, 2009 4:38 pm) Wash all the dirt and grime out, hit it with WD40 to stop any rust, then go with a good dry lube. You want to use a spray on dry lube liberally, but avoid things like grease as they will tend to catch and hold road grime. Replies to this message: bluejay5 (Oct 29, 2009 7:34 am)

#3446 of 3449 95 GMC Jimmy Rough Idle by groby Oct 29, 2009 (9:53 pm)
I have a 95 jimmy. it has started to idle rough, and now comes close to dying when I stop suddenly or shift gears. it also failed emisions testing in the idle with 391 HC (PPM). check engine light is on but i can't get a scanner to work. scanner says it can't make a connection with my car? Any ideas? thanks Replies to this message: Mr_Shiftright (Oct 30, 2009 9:14 am)

Replying to: groby (Oct 29, 2009 9:53 pm) Well you're kinda screwed if you can't get a scanner to work because you'll probably need one to turn that light off. You can't pass a smog test with that light lit up.   I think first thing I'd do is try another station to see if their scanner works. If not, you could have an issue with communicating with your car's PCM.   As for the high HCs, this is usually indicative of a misfire, which could be tune-up related, or a bad 02 sensor, just to name 2 things. Also could be a lean misfire, caused by vacuum leaks.
