1991 GMC Sierra - Page 8 - Answered Questions & Fixed issues

that problem is usually in the ignition switch.wiggle the steering wheel and the key at the same time in and out back and forth on the key if its going to come out its going to take a little more than the normal turn sometimes a little luck. make sure youre in park too ive seen that happen where the vehicle hasnt latched all the way into park.

With the radio off, hit set then use the scan and seek buttons to set the time. When you are done, hit the set button again.

a vacuum pipe air leak.......

OK, changing an AC motor can be easy or tough depending on the model car.

What year, make, and model car do you have?

You hit it on the nail, you have check every thing we would have checked here at my repair shop, it's going to be the turn signal switch, as you now the brake light circuit run's through it and more then likely your center top brake light works.Bad switch (turn signal).

It could be a dirty fuel filter. If the filter has been changed and it still shuts off, have the fuel pressure tested. Low fuel pressure will give the same symptoms of a dirty fuel filter.

2300????? Huh. I though they were 1500, 2500. i could be wrong. ususaly in the 3/4 tonne vehciles, they have a small block V8. I hae seen quite often a 350 cubic inch...but, depending on your transmission and engine braket mounts, not to mention mechanic skills and fabrication abilities, you could put whatever you want in it...As i said, probably a 350 small block is what was in there...probably

Hello! Let's make certain we are talking about the same item...You are changing the oil pressure sender; Correct? It has a single wire (Gray in color) and is located near the distributor; It is a lot easier to remove if you pull the distributor...Don't forget to mark the position of the rotor...

I’m happy to help further over the phone at https://www.6ya.com/expert/david_6df67de3b14de867

there should be a picture on the top of the radiator showing the diafram

each wheel behind the rotor

The ignition switch is located on the top of the steering column underneath the dash.

1. Remove the cover panel from under the steering column and you should see the bracket that holds up the steering column, but before you un-bolt the bracket to lower the steering column, you must remove the clip holding the shifter position indicator cable to the column. (put the shifter into drive and you should be able to see the screw that holds the shift indicator cable adjusting clip to the steering column)

2. Remove the bracket holding up the steering column and carefully let the steering column down as far as it will go, the steering wheel will probably be resting on the seat.

3. You should now be able to see the ignition switch on the top of the steering column, and the two mounting bolts. The high beam switch might share the upper ignition switch bolt, and you will then need to remove the high beam switch before you can remove the ignition switch.

4. Remove the ignition switch mounting bolts (usually 5/16 but I have also seen 11/32 and 3/8 size bolt heads used)

5. Remove the ignition switch by lifting straight up from the column to dis-engage the interlink rod from the ignition tumbler assembly, you should then be able to pull the ignition over towards you just enough to dis-connect the two wire connectors to the switch and then you can remove the old switch from the vehicle. (the interlink rod is sticking straight up from the steering column and it slides up and down with the operation of the key, it fits into a notch in the ignition switch and that is what actuates the switch)

6. Reverse procedure to install new switch, starting with re-connecting the wire connectors and be sure that the interlink rod goes into the notch in the ignition switch.

7. When the switch has been re-installed and is ready to be adjusted, turn the ignition switch to the "ON" position and hold the key in that position and slide the ignition switch up and down until it is in the on position and your dash lights come on, tighten up the ignition switch mounting bolts and then test the operation of the switch, and re-adjust if necessary until the switch operates properly.

8. Adjust the high beam switch by pulling back on the high beam lever and just taking up the slack in the actuator rod to the high beam switch, test the operation of the high beam switch and re-adjust if necessary.

9. When the steering column is bolted back up, re-attach and adjust the shifter position indicator by placing the shifter in neutral and slide the adjusting cable clip until the shift indicator is pointing in the neutral position, test the function of the shift indicator and adjust as necessary.

while motors warm up the computer supplies information so the motor works well. After it warms up the computer is guided by sensor information. It sounds like a sensor is going bad. Try to get a scanner reading which might show which sensor. The two main imputs to fuel are oxygen sensor and temperature sensor. Real common for O2 sensor to go bad.

Make sure you installed your fuel pump correctly, also check the fuel filters directions may be back wards

Try adjusting the shift cable or replacing the neutral safety switch.

See what you are loosing, spark or fuel.
(Note that a working fuel pump will build pressure, but if the injectors aren't "firing", you still won't get fuel.
Yours sounds like a possible ignition module.

V-6 1-6-5-4-3-2 V-8 1-8-4-3-6-5-7-2 Both turn clockwise. Number 1 is at the 5 o,clock position standing at the radiator.

Try putting a little heat to the nuts.A map gas torch with a flex hose if you can find one or cutting torch if you have access to one.I am not sure if there is enough room to fit a nut splitter in there.

the rods in back of the handle probably came off.

change the fuel pressure regulator as well located on the fuel rail

Release your gas cap, check the plug wire resistance and also check the EGR valve
