Question about Chevrolet Blazer

1 Answer

Does anyone know why the 2000 blazers have an issue where they will not start when it rains???

My 2000 blazer has 147K miles and for some reason when it rains it won't start most of the time. A friend had one and had everything from plugs to all sensors changed, they just got rid of it after spending hundreds of dollars, at state certified repair shops. I am sure that someone must know how to fix the problem!!!

    Well it isn't running when it won't start,so it isn't storing a code I can retrieve,I have good spark,plenty of fuel,no moisture inside the cap, no carbon tracing. my cap and rotor wasn't the cheapest($55.00) AC plugs,Bosch wires,and there are some times when it rains that it will start,As I said earlier my friend had spent hundreds of dollars in parts including all sensors,at a very reputable repair shop. Nothing worked in her favor, and I also know other people with the 4.3 in other trucks that are having same problem. I really like the blazer and don't want to get rid of it!!!

Hello Mr. Guy with Blazer.
Firstly, do you have a check engine light? If so, please do go by the code and check references.
If not, then does it have a distributor? If yes, then please check the distributor cap and rotor as condensation can cause issues with pickup or spark.
If no, then check the ignition coil, ignition module and other sensors.

SOURCE: 2000 chevy blazer braking problem

sounds like your abs is kicking in. they are referring to the wheel hub/bearing assembly. not locking hubs for 4wheel drive. if you have a sensor dropping out the abs unit thinks a wheel is locking up and activates. this is why you feel the hopping and could be the hub or just the sensor

Dear Gandhi
1) You better check the 'Idle control relay' - and pray this is not your computer - who may be shorted ( The Computer that govern all elec. functions in the car - is also getting signals from your Mothor Mounts' to ensure a more balanced ride' If one or more of the Motor Mounts ( There are 3 ) are defective - they send a signal to the computer - and the yellow light ( Check engine soon) - will appear'
2) A Computer can only be fixed by a Nissan dealer ( est. $750 ) 3) The Idle control valve - can be adjusted too ( Again - by a Nissan Dealer only .
4) It is NOT an easy problem nor cheap . In short - your best bet is with the dealer - and ask them for a diagnostic ONLY ( est. $100 ) Don't tell the dealer what YOU think or did .......just tell them the 'Yellow light comes on' .......they'll take it from there.
Sorry I don't have better news today .

Best of luck

SOURCE: 2000 chevy blazer won't start after changing fuel filter

if it does not start after you check your distributor cap that means you took the car out of timing, when you put the distributor cap back on you did not put it is the correct position, now you need a mechanic to get the timing of the engine

Is the BCM on a 2000 Chevy Blazer S-10 plug and play

I would say no. You have the resistor key for the ignition, right? The bcm is programmed to read that resistance or it will not enable the start relay.

Transmission issue, when in reverse heard a clunk, then a whining sound....later there was no reverse...2001 chevy blazer I had the exact same thing happen just today on a 2000 Chevy Blazer. Two weeks...

The loss of 2nd 4th and reverse is a common failure on the 4L60E. What happens is the reaction shell has separated from the sun gear. Often a whole transmission is cheaper simply because the remanufactured unit from GM are reasonably priced and the warranty is 3yr 100,000 miles.
