Replying to: gorbey (Sep 09, 2008 9:33 am) 1. It can make the idle irratic 2. Located on the front of the engine. Go to Autozone online and you can look up the part and see what it looks like. 3. Easy repair.

#38 of 65 Bad relay by duntov Dec 27, 2008 (6:07 am)
If the accessory control switches are functional, it is likely that the relay for those accessories is bad. Replace the power door lock relay because it is also common to the other accessories you mentioned. You can use Power Door lock Relay from AC Delco F1788, $42 (GM 88922752 - MSRP $78 ); Standard Motor Parts RY246, $26; or Air Tex 1R1269, $23. That relay was used on many GM vehicles with power door locks since 1980. The relay is located behind the headlight control switch cluster on a 1989 - 1995 S10 Blazer. I am not sure where it is located on other GM vehicles. If a auto repair shop replaces the relay, they will charge 1/2 hour labor cost plus the cost of the relay. That will be about $100+ total .replacement cost.   A bad relay can also cause a 200+ ma parasitic power drain on the battery even when the ignition key is off. If the vehicle sits for a week or two without being started, the power drain could completely discharge the battery, especailly if the battery is over 18 months old.

Replying to: RABIII (Jan 02, 2009 10:51 am) P0719: Do your brakelights work? This is the code for low voltage in the brake light circuit. Blown fuse?   P0753: Transmission solenoid related. How is the transmission shifting? Could be anything from a shorted harness to the tranny to a bad shift solenoid. Replies to this message: RABIII (Jan 06, 2009 11:56 am)

Replying to: jlflemmons (Jan 04, 2009 8:59 pm) p0719 - Corrected by installing a new break switch and fixing a frayed wire.   p0753 - Corrected by replacing both solenoids in trans.   $54 in of parts & $314 in labor to to pass emmisions test.   Go figure.....
#42 of 65 2001 Chevy Blazer S-10 4.3L 2 door by Corinne1961 Jan 21, 2009 (11:21 am)
I've had some problems with my blazer. It started skipping/missing a little, not much. Drove it from a cold start about 3 miles to get gas, gave me trouble cranking but did eventually crank. Did this a couple times. Drove it between these events and then one day at work tried to leave and wouldn't crank again, at all. Tried a few days later, no luck. Been about 3 weeks and this morning it did crank, idled for about 15 minutes, drove it a couple blocks and parked it, shut it down, restarted it but did start hard. Talked with a mechanic and was going to drop it off for them to do the fuel pressure check and all. Cranked right up, ran a minute, then stalled and now it won't crank again.   We put a new fuel pump on it about 1-1/2 yrs ago but the oil changes haven't been kept up for the last year or so. The check engine light has been on for a long time but never did anything about it because it seemed to run fine. We are short on vehicles and I need help. Hoping it's not the spider injector. Can anyone give me direction?
