SOURCE: 2001 GMC Sonoma Ext cab 4.3l, quit while running

Pull plug wire and install a philips screwdriver into the plug wire get it 1/4 inch away from a good ground and crank the engine over, is there spark? if so check that you have fuel pressure buy renting a fuel pressure test kit from schucks or auto zone and turn the Key to run position with the gage hooked up, it should read 50 PSI turn key off and wait 20 seconds should still have 20 PSI of fuel pressure, if no fuel pressure check fuel pump relay, then check fuse to pump. if you have a bad relay and are not getting fuel then check the oil pressure switch to see if you have oil pressure at the switch if no pressure then the oil pressure safety switch has died and needs to be replaced and should stark after replacing. If you have fuel then check the timing to see if you slipped timing belt.

SOURCE: my 1998 gmc sonoma wont start when cold. fuel

A VERY COMMON CAUSE OF THAT IS THE ENGINE COOLANT TEMPERATURE SENSOR, YOU WILL NEED TO VERIFY PROPER OPERATION WITH A LIVE DATA SCANNER, BEFORE U TURN IT ON IN MORNINGS OR COLD, COLD ENGINE LOOK FOR CTS READING IT MAY READ -40 DEGREES, IF SO THEN SENSOR IS MALFUNCTIONING, BUT WILL NOT SET A "SERVICE ENGINE SOON" LAMP WARNING. OTHER WAY TO CHECK IS TO DISCONNECT SENSOR, I AM ASSUMING THAT WEATHER IS ABOVE 20 DEGREES. LET ME KNOW IF THIS HELPS, CAN ASSIST YOU FURTHER WITH UPDATES

SOURCE: need to replace the wiring for a 1998 sonoma on battery need to replace the three long wires

Why would the wires need replacing. You can avoid a lot of extra work by just replacing the battery clamps (terminals). Just make sure the polarity is correct (Red is +, Black is negative ) Always connect the negative wire to the battery post last to prevent arcing. Wear safety glasses when working with batteries as an explosion hazard is present. Use conductive grease on battery post to prevent corrosion.

How do i disarm warning chime on 1998 GMC Sonoma


Worn out key cylinder or ignition switch. Cant tell when key is off. There is a wire which as you put in the key it makes contact as the the key pushes this metal contact up. You can unplug it. It should be a blue wire you should be able to see once you remove the covers of the colomn.

1998 sonoma won't start


Your Battery is Corroded or Bad.... Pull your Battery, Clean the Terminals, Charge your Battery and have it tested and if it is bad, replace it. If it is Good, then Clean the Terminals and the Post REALLY GOOD and reinstall and your problem will go away. If your Battery is Good, test your Alternator. Your Battery should have 12.6-12.8 Volts. When it is Running, it should be 13.4-14.6 Volts Depending on your Alternator and Voltage Regulator

I have a 1998 GMC sonoma that wont start. we have already replaced the starter (new starter works perfectly) and it still wont start. we were wanted to check the wire that goes from the key switch to the...


Let's say that the battery and it's cables are good and charged and tight. and clean. You walk up and unlock the car and get in and close the door ( is the security light on? ) if it is can you put in the key and turn it on and does the security light go out? If it does'nt then you'll need to reset the security system. The GM way. With the doors all closed and the driver window down, reach in and turn the key to start and let go. the security light will be on steady, between 10 and 15 minutes it'll be out. Turn the key off and turn it back on and the security light will be back on, agian wait till it goes out. Again after it's out turn it off and wait a sec. and turn it back on, the light will come back on. again wait till it goes back out. this time ( the third time ) turn the key off wait a sec and then turn it to start and if everythings alright it'll start right up or crank OK and you'll have to finde another problem but the security system is'nt going to be it. If you battery is'nt good enough to do this you need a new battery anyway and your going to have all kinds of troble till you chcnge it.

1999 GMC sonoma starte installation


2.2L Engine remove protective shields as needed then remove front exhaust pipe. Remove the brace from the engine to the clutch housing, then disconnect starter wiring. 4.3L Engine 2 wheel drive just remove the right front tire and you will have access to the wiring. 4.3L Engine 4 wheel drive you must remove the differential carrier shield if equipped then remove the starter bolts and rotate the starter to get access to the wiring. Good Luck.
