#1404 of 2018 need help figuring the diagnosis
Dec 22, 2005 (8:49 am)
I have a 2000 GMC Sonoma and I was driving down the highway going about 70 mph when it just turned it self off and wouldn't restart. It acts like it is out of gas but it couldn't be because I had just filled the tank not but minutes before. It's had all of it's scheduled maintence through out it's life and even with the one previous owner.
My peliminary thoughts are that it's either a fuel filter, the fuel pump, or may be the aniti-theft mechanisim malfunctioning. Has anyone else had a similar problem if so what was the diagnosis? Just trying to save my self some time and money and get er' back on the road.

I also have a 2000 Sonoma. My Sonoma als recently went dead. I turned on the truck, it ran for maybe 3 seconds and then it went dead. We tried to jump it too but nearly melted the cables. There is no electricity at all, no lights on the dash board, nothing. There is also no head lights. Any idea what happened?

This does not sound good ...
As it "did" start and run a few seconds - I'd check the following;
Possibility # 1.) Battery is OK but you have have a major cable open - Check Cable leads to / from battery, Engine, starter, Grounds to Engine, frame, etc. etc. Remove the Batery leads, Check the battery Voltage, Check the cables / resistance on all leads. Use a Volt/Ohm meter ...
or - 2.) You have a real major DEAD SHORT. (the fact you melted your jumpers indicates this my be the problem) - A Short In the battery - or in the Truck. Remove the Battery leads, Check the battery for Voltage and if at 0 volts - check for short between terminals. Check the +12 cable for contunity to ground. If it's in the Truck - Start disconnecting ONE cable point at a time with the OHM meter hooked up and Isolate the short ...
I'm hoping it's the battery - or an easily found short (Cable rubbing, bad starter/Alternator... Alternative is you fried all the electronics .... Hope not ...
Good Luck - Let us Know what you find!!!

Yes, Ive noticed that the light gets brighter.
What could be the problem exactly? Where can have it checked?
Sorry about the bold type.

When the Truck senses a problem with the ABS - to puts the light on at under full brightness ...
Could be a number of ABS things - but check your sensors on each wheel. Wires my be cut - sensor / bracket bent - too far away from the rotors - so it can't sense the wheel spinning ...

Key on, engine off, jumper ALDL terminals A and H as shown below. Count the flashes on the brake warning light and post the codes:

Dec 26, 2005 (12:47 pm)
I have the same problem with my 2000 Chevy S10 Blazer. The power windows don't work at all. The fuse is fine, but the wiring diagram says there is a 30 amp circuit breaker that I can not find in the I/P fuse panel or in the under the hood fuse box. Anyone know where this circuit breaker is hidden or what else I should look for?

2000 S10 with 2.2 Litre, 85000 miles. Truck would start and idle fine, and it would even run good for about three miles. Then, it suddenly had no power. You could turn off the ignition, and it would start right up, but lacked power, coughed and spit.
Code read po171 which is lean on left bank. First, I changed plugs and fuel filter...no change. Changed both of the 0/2 sensors..no difference. Changed tp sensor and the map sensor...same thing. Disconnected exhaust to check for bad Catalytic converter..same thing.
Fuel pressure was fine....at idle! At speed and heavy throttle, the pressure would fall quickly. I changed out the fuel pump and PRESTO!!!! Problem solved. Damn thing runs as good as new now.
I pulled off the bed of the truck and the fuel tank was right there. 8 15mm bolts, and a couple of electrical connectors and it lifted right off. Made my life easier.
