Question about 2000 GMC Sierra

1 Answer

Stopped running on the highway as i disengaged cruise

Appears there is no problem with battery. engine wants to turn over but only sputters slightly, will not start or run.checked small pressure valve at injectors and seems to have plenty of pressure and fuel. tank is half full. before romoving truck from flatbed wrecker with truck on incline position, it started but was certainly starving for fuel and could not accelarate without killing motor. 3 or 4 days prior security light came on during starting and went out.

It sounds like ou may have a weak fuel pump. if all it does is sputter then its starved for fuel. you might also check for water in the tank if theres enough water built up it wont run right

What does the MIL code "PO 320" mean, please?


code p0320 refers to cam shaft position (CKP) sensor/engine speed (RPM) sensor--circuit malfunction=== causes --wiring--CKP/RPM sensor ---ECM
because the engine runs ok until it is on cruise control I would be investigating the RPM sensor for a fault
The cruise control takes its control from the RPM sensor and if that circuit is interminable the the cruise control doesn't know what rpms to maintain.

Does the speed sensor being bad make the engine run rough?


Yes the speed sensor could affect the cruise control, no it would not have any affect on the engine performance.

2002 Sable sedan choke/missing/sputtering intermittent


The PO 316 is still misfires om first 1000 revolutions
so the shop did a poor job for you on resolveing the
cylinder misfires

Try a diffferent shop

Have to clean the MAF Sensor & replace upstream
oxygen sensors if over 100,000 miles

Need the correct oem spark spark plugs/any brand

No reason the gas filter should be clogged unless it was in
the car for 10 years

Fuel pressure should be checked

Need to check for cylinder misfires on a road test of 20
miles or more with professional software in Mode#06

Cruise control not working when it was it seammed to make the motor run very ruff when i disengaged it by using brake pedal


If the cruise control makes the engine seem to run very rough until disengaging it, there could be a problem with the engine itself. As, most cruise control systems just pull on the throttle cable to maintain speed on the highway based on setting the speed with the button.

So, I would look into the engine maybe having an issue with spark plugs, or wires, or another tuneup or mechanical issue.

98 plymouth breeze slight jerking and sputter while accelerating and cruising. no rpm or speed loss. battery light came on first, no check engine light is on?


If your battery light is on, you need to have the alternator tested. If you have a voltmeter you can test it yourself. It should have at least 14 VDC at the battery with engine running.
I'm not sure this is related to the sputtering, but it might be.

I own a 2005 GMC Canyon Five CYL and the cruise control stopped working last niight. You push the button and no cruise. I checked the fuse and it is ok I exchanged with another 10AMP and no change still...


Start with the simple and check the fuses and the Stop lamp switch. Check your brake lights, if they're not working, the cruise won't work either. If they're not working, check the fuse for them, if the fuse is fine, then take it into the dealer, there's been a recall issued on the brake switch, so it should get fixed for free.
Cruise Control Disengaged
The powertrain control module (PCM) disengages the cruise control operation based on the signals from the following switches:

* The stop lamp switch
* The TCC brake/cruise release switch
* The clutch release switch, if equipped
* The cruise control On/Off switch

The TCC brake/cruise release switch and the stop lamp switch are mounted on the brake pedal bracket. When the brake pedal is applied, the normally closed TCC brake/cruise release switch opens and the normally open stop lamp switch closes. The PCM detects a low signal voltage on the TCC brake/cruise release switch signal circuit and a high signal voltage on the stop lamp switch signal circuit. When the clutch pedal is applied, the normally closed clutch release switch opens and the PCM detects zero voltage on the CCP switch signal circuit. The vehicle speed stored in the memory of the PCM will be erased when the cruise control On/Off button is turned OFF, or the ignition switch is turned OFF.

The Cruise Control System will disengage when the PCM detects that a driver override function has been active for approximately 60 seconds .

When the Cruise Control System is disengaged, the PCM sends a class 2 message to the instrument panel cluster (IPC) in order to deactivate the cruise control indicator.

Cruise Control Inhibited
The powertrain control module (PCM) inhibits the cruise control operation when any of the following conditions exist:

* A cruise control related DTC has been set.
* The vehicle speed is less than 40.2 km/h (25 mph) .
* The vehicle is in PARK, REVERSE, NEUTRAL, or 1st gear.
* The engine RPM is too low.
* The engine RPM is too high, with fuel cut off.
* The vehicle speed is too high, with fuel cut off.
* The system voltage is not between 9 volts and 16 volts .
* The Traction Control System (TCS) is active for more than 2 seconds .

Thank you for using Fixya and start with replacing the stop lamp switch. Even though the brake light work, it;s been known for that switch to cause your issue. that's way there was a recall for it.

When driving my kia it seems to stall but not cut out just momentarily ? and i have a light on dashboard look like a little tap .... slight noise from engine sounding a little like loose belt maybe


2001 kia sportage, 164,000, driving on highway and engine starts to sputter momentarily, then runs good , then sputters, runs best if you barely push gaspdal, to much pedal and sputters again

Continous surging and stalling


Per your description, I would suspect a fuel pump issue. When the fuel pump is running the pump impeller heats up. On an older pump the impeller can begin to seize up and momentarily stops and starts. Some times it just stops and has to cool down for a couple of minutes, then is ok for a while.
To test this theory, when the engine stalls and stops, your mechanic can use a rubber mallet and hit the bottom of the gas tank, this will free the pump impeller and the car will start again.
Or, have him install a fuel pressure gauge and go for a drive. If the pressure begins to fluctuate and drop, you know the pump is causing the issue.
Good luck, let me know.

Car suddenly turns off


Check your RPM sensor.  Mine did virtually the same thing.  It was NOT the fuel pump like Audi dealer said-after I repaired it.
