1994 GMC Sierra Questions & Answers
My truck seems like is not passing gasoline,
I would start with the ground by the fuel tank that leads to the fuel pump. Corrosion has been known to cuase erratic fuel issues on these trucks. Remove the ground lug (bolt) and scrapand wire brush the frame good ,the ring terminal at the end of the wire and the underside of the bolt. Check the wire end for rot (if it flexes too much) replace the ring terminal and put some silicone or heavy grease under it and attach securely to the frame. If that doesn't work you may need another pump I had to replace my replacement after 5 years (buy a mid range priced pump) not the least expensive from Am*zon or R*ck Auto.
Rear wheels not spinning. Front wheels spin when in 4 drive.
Hi First of all check the adjustment on the rear wheel thats sticking sometimes the brake pad comes away from the metal it is fixed to this maybe the case on your vehicle, the make & year of vehicle would help further but I a sure you got something to check now. Please leave me feedback, Malcolm Campbell.
1994 Sierra C/K 1500.
The lock cylinder is the most likely suspect and is in stock at your favorite local auto parts store. To change it, the steering wheel has to come off first. The lock cylinder is held in place by one screw. If there are more problems, you will see them when the steering wheel comes off.
94 gmc 1500 transmission mount broken??
Let me get this clear.. you did not remove the cross member to drop the pan?? WHY?.. If you broke the bolt loose that is made into the transmission mount.. you need to be able to tighten the mount somehow.. if you can't tighten the mount, yes, you need to replace the mount . NEXT TIME - Use a jack stand under the front of the drive shaft to hold up the transmission.. this will make the job easier!!
94 gmc 4x4 1500 overdrive sometimes works
Check for a transmission speed sensor fault (OBDII scan). Loss of speed sensor signal will result in no torque converter lock up, and no overdrive. Also transmission filter should have been changed at 80,000 miles. Age of your vehicle(1994) warrants the filter service. Transfer case (4WD) needs to be serviced as well.
