1993 GMC Sierra - Page 9 - Answered Questions & Fixed issues

Shift module? Are you talking about a control for the transmission? The Engine computer controls the transmission. What kind of problem do you have? I can likely help.

open hood, passenger side of car, right past the air cleaner is a tube (snorkel) MASS AIR FLOW SENSOR going with 4 wires going into it,
that should be it! thanks 4 inquiring

THE ELECTRICAL TERMINALS ON AC CLUTCH COIL IS BROKEN OR DAMAGED THE CLUTCH COIL HAS TO BE REPLACED.YOU DONT HAVE TO REPLACE THE WHOLE COMPRESSOR.YOU WILL NEED COIL REMOVER TOOL AND BEARING DRIVER TOOL.

is it the gland nuts leaking or the pipe itself has blown, gland nuts tightened if seals are okay, pipe itself needs replacing

Yes, the fuel pump could be bad, but the sending unit and gauge should be replaced at the same time necessitating taking the gas tank down.

Your clutch has welded itself to the flywheel and should need extensive work to get it off. Go to a mechanic with the truck and ask him how much this will be as I have never seen, only heard of this happening to a truck of that size. Thanks for asking!

I see this problem fairly often and you can get the fitting out but you need a bit of patience to do so. I remove probably 6 of these a year and how I get it out is to take a new, very sharp, hacksaw blade [just by itself] and very carefully using the blade by hand cut a 2 or 3 equally spaced vertical grooves through the fitting. The fitting is a fairly soft pewter like metal and cuts fairly easily just the same you want to just cut through the fitting until you are just up to the threads in the intake and not beyond. Once you have these grooves cut you can take a very sharp pointed chisel or center punch and with a small hammer you can catch the edge of the fitting and and tap & peel it away from the manifold piece by piece to remove it. I've tried several specially made "easy outs" to remove these but the problem is that the fitting is stuck so hard to the intake that it just will never turn out again. I replace these failure prone fittings with a simple hose barb type brass or steel fitting and then replace the heater hose with a new piece of plain hose. A really tough broken fitting may take me a half our or so to remove but expect to spend a couple of hours on your first one. Good luck!

adjust the idle, check the carburator system...., also check the battery and alternator.

It only does this with a trailer hooked to it? Do you know what transmission it has in it?

Try checking to see if you have dislodged a vaccuum line, Was the distributer loose and and been moved? ensure the cable for the automatic choke is still connected on the carby, hope this helps

The line when you have the air conditioning on it feels cold to the touch,almost freezing, that's the low side.

If it is for the gas gauge, it is built in with the fuel pump in the gas tank.

It would have R134 in it. You'd need to see if there is freon in it, if it's low, or if it's all leaked out. You may need new O rings, new lines, new condenser, or a new compressor. Could run anywhere from a couple hundred dollars, upward to $1000.

Go to your DMV office and pay for a duplicate title.

Did you try a 3 stage injector cleaner and intake snake. Cleans throttlebody of carbon. I had to push a truck into the shop because it would barly idle did all that and it did wonders. Guy squaked the tires leaving because of the power that was given back. Also high mileage oil, Full synthetic on older motors can cause pan gasket sweats.

Oxygen sensor[s],map sensor and fuel pressure regulator.Although you should have a check engine light "on" with any sensor malfunction.I would look at fuel lines for a leak under vehicle.

rack and pinion needs replaced

most auto stores can get it for u or online book/auto parts stores --rebuild is not the easiest thing to do will need certain tools and a press -- also need to know which trans u have 93 had 2 [count the bolts on the pan] the 4L80E has 17 pan bolts --the 4L60E has 16 bolts ---easiest would be a salvage yard or u pull it yard most trans are under $100 good luck

3 things a engine needs to run. Gas, air and spark.
You have spark so.........

Front driver's side.
