Question about 1999 Chevrolet Blazer

1 Answer

Wiring Problems? I have been having on going problems with my blazer. Took it to the garage and was told that the security fired the wiring to the fuse box and the neutrual position sensor. They fixed that problem, my truck ran great for a couple of weeks and then quit again. Now I've been having problems with it starting again. I have to start the truck with a live wire to actually get it started. I was told that the wiring harness in the steering column could be bad. Took apart the dash and the wiring harness under there is chopped to pieces. All the connectors are cut off and the wires are all taped together. What should I do next?

If the chopped and taped wiring was done by the shop that worked on it, and it worked after they were finished, It's likely that they did the right job (short of replacing the entire harness) but may have done a sloppy job, resulting in your present problem. Removing burned connectors and joining wires is OK, but they should be soldered and carefully taped, otherwise connections can break, or shorts can happen. Check a few connections they made...If not soldered, either bring it back to them and have them do it correctly, or get out your soldering gun and one by one, solder them yourself. One important point though...If you find any wiring that is beginning to melt, then they have fixed the result of the problem but not the cause...That will then need further diagnoses.

I'm having problems with a 2002 Chevy Blazer 4.3L not turning over after changing the plugs

Check the firing order. If you took all the plug wires off at the same time, then there is the problem. Back firing out of the intake is a sure sign the firing order is wrong.

My 1997 chevy blazer caught on fire. The problem was the wireing. Is there a recall on it.

Call any GM dealers sevice dept. wioth your VIN in hand and tell them that you've had a wiring issue (don't tell them of the fire just yet). and ask the service writer to run the vin for recalls or service bullins about the wiring or the items that were involved in your fire. If the vehical burnt down you might decide to let officials handle it ( fire or Police) as they may say you need a lawyer to help you recover even if GM knows about a problem. The one I know about is the O2 senser wiring shorting to the exhaust pipe and the resulting fuse failure makes the vehical shut down. but theirs no fire.

I have a 1992 subaru svx with a couple of problems. 1. all of the gauges arent working except the tempeture gauge and i dont know why. everything else works inside the car lights, a\c, radio. ive checked...

the alarm system was most likely not installed correctly, when you install an alarm system you need to know what you are doing or you can cause countless problems in wiring, as for the gauges i would suggest checking all wiring behind the cluster (gauge panel) look for wires that have been cut and if you can not find anything i strongly suggest taking it to a mechanic for trouble shooting.

Sounds like your fuel pump is going bad. Have your mechanic do a pressure test on it.

Look closely at the wiring on the starter. It sounds like you may have reversed the two smaller wires. Looking at the starter from the wire side, the small connection at the 2 o'clock position is the one that fires the solenoid, (6 o'clock being the big wire into the starter)

S10 blazer lacks power, bogs under acceleration

Check your coil output, buy a cheep spark tester. Pull of a spark plug wire and plug in the tester(ground the other end), set it to bridge a gap for 30,000 volts.Have someone start it and make sure the spark will jump the gap on the tester.Danger-Very high voltage! It will light you up if your touching the tester while the car is running!You'll be able to see a bright blue spark(and hear it as well) if your coil is good.If it's a yellow thin spark it's probably the coil.
If you have good spark, check the fuel filter and fuel pressure at the fuel rail.
Back firing could be timing,cam position or crank position sensor.Worst case scenario, timing chain or belt.
