Question about 1998 Chevrolet K3500

1 Answer

1998 Chevrolet C3500 dies randomly when driving down the road - uphill, downhill or flat surfaces. Typically doesn't happen when it's cold. Sometimes it starts back up and sometimes it doesn't. When the engine dies, the Security,brake,anti-lock and service engine lights all come on. Sometimes you hear a clicking under the dash. A new ignition switch was just installed and diagnostics done with no results???

U have an intermittent electrical connection causing the hassle. Check and clean all wiring junctions, etc. Also work the connections by sliding them in and out many times to remove any oxidation. U have to remember that a car's electrical system is low voltage and the slightest bit of corrosion can screw things up - example is dirty battery terminal wires with a new battery. Car will not crank but clean the terminals and away you go!!!!!!!!!!!!

SOURCE: anti lock brakes activation

if abs activates when it should not,,, it means abs module senses one or more wheel sensores under 3 mph and the other sensores are above 3 mph. .the cause of this is usualy a bad wheel speed sensor or excessive air gap between the sensor and ringwheel. you need an abs data scanner to hook up and go for a test drive to find out which sensor is the culprit.

If it has injectors it has a ecu, if it has an ecu it has a diagnostic port (normally under the drivers/passenger dash) if you look down at seat botton level you should see a small black port) You can go to any auto zone or parts place and they will scan it for free. You may have a head gasket issue with overheating or your cooling fan(s) may not be turning on. Check the codes first

sounds like you have a wheel speed sensor going out.. need to have it scanned to see which one is dropping out and making abs kick in..

Won't start when facing uphill or flat only when facing downhill.


sounds like a fuel pump fault, gravity is the only thing feeding the engine, then when engine is running the suction is sucking fuel in.

my younger brothers' truck did the same thing and there was a relay up under the dashboard that would get hot and shut of(kind of a circuit breaker unit) most of the operating systems will flash at you when only battery voltage is available which explains the lights coming on..these newer trucks also have a performance chip in the system that will act up when it gets warm also..replace this and you may be ok..let me know what happens also.. good luck.

Died and wont crank


If it died and won't crank, sounds like you lost power to something.
Does the warning lights come on when you turn the key on ?
Got headlights ?
A mechanic would check for voltage at the starter and work back from there.

I have a problem with my 2004 impala 3.8 V6 I will drive down the road and it will randomly die and won't start back up. It will turn over and everything but won't start. But if you let it


Possibly a crankshaft position sensor had the same problem with one of my former vehicles. Be careful buying a new one though it is an electronic part and it is not returnable at most part stores. That is what it sounds like to me though.

Teryx in limp mode


need more info what happened when it wen't into limp mode. were you just driving down the road, uphill downhill? there could be any number of reasons. Limp mode is so that you don't wreak the engine. What year car? did it throw an engine light. if so have it read to find out what is the problem. Other causes low antifreeze, low oil, trans overheating. You can try to unhook the pos battery cable for 10 minutes, if that does't clear the computer then you will need to see the dealer.

Cruise control will not maitain the speed it is set on. going up a hill it gets slower and going down a hill it gets faster


My experience is that cruise control works on level roads, uphill you have to control speed yourself same for downhill. Exception is very powerful cars. Did it maintain speeds before? (uphill + downhill)

Today suddenly my 4runner 98 V6 started to rattle in a slow gear and when going uphill the car had a sulfur smell but only when pushing it uphill the engine light came on but turned off after 10 minutes...


Take it into your mechanic ASAP before you throw a rod and destroy your engine, check oil level also...DO NOT DRIVE IT ANYMORE or you may be looking for another car soon.
