20 Most Recent 1995 GMC Sonoma Questions & Answers


These old style check engine lights are pretty much just service reminders, and as such can be reset generally just by taking off the negative battery cable for about 1 hr. Still need to read codes, though. Check all your vacuum lines.

Make sure all the ends on your battery cables are clean and tight. I got a tow in because my car would not try to start even tried boosting to no avail. All my lights and radio was working but they said the cable was corroded and would not let the full power work. We replaced the battery cables and worked like new now.

Thier is no adjustment !

Valve lash is obtained through the use of hydraulic valve lash compensators. No provision for adjustment is provided.

There are several fusible links connected to the positive terminal of the battery and in the junction block.

3 on each side of the block. Access them from the bottom. 1 1/2 to 2 inches in diameter. There are also 2 of them between the engine and transmission.

Why did it overheat, did you fix the overheating? Are you saying it cranks good but won't start? If it cranks good but won't start, check fuel--spark--compression. Make sure battery has a full charge and battery connections all good. If the battery is down, we can't do any testing. At the starter motor motor, two voltage circuits, one comes from the battery, hot all the time. The other voltage circuit goes hot with key in the crank position is wired through clutch switch. The starter motor grounds through engine block. Any testing at starter make sure tranny is in park or neutral and parking brake is set. You can have the starter motor tested.

You should be able to see the lever that the cable pulls on to release the e-brake. You may have to remove a trim panel or two to see up in there. Use a screwdriver to pull that lever forward. Keep your face away from the pedal (dont ask how I know this.....).

In the video below you can see the lever that the cable attaches to at around 1:15 into the video. I know its not the same vehicle but the concept is the same.

Sounds like you have a vacuum leak. Use a can of brake parts cleaner to check for the leak. Spray you vacuum lines and listen for the engine RPM to change and when it dose you will have found your leak.

its an electric pump installed in the top of the tank with the inlet/outlet.
