GMC 1500 Pickup Problems
Intake Manifold Gasket May Leak Coolant or Engine Oil
The intake manifold gasket may develop and external engine oil or coolant leak. In some cases, an internal coolant leak may occur causing coolant to mix with the engine oil. Running the engine with a coolant/oil mix may result in engine damage. Replacing the intake manifold gasket should correct this issue.
Inside/Outside Door Handles May Break
The inside and outside door handles are prone to breaking.
Windshield Wipers May Fail Due to Faulty Wiper Motor Control Board
The windshield wipers may not work intermittently due to a faulty wiper motor control board. Our technicians tell us that lightly taping on the wiper motor when the fault occurs should temporarily get the wipers working again. Some vehicles were recalled for this problem and some were not. You will need to check with your local dealer to find out if a specific vehicle was included.
The Fuel Pump May Fail Causing the Engine to Stall or Crank Over But Not Start
The fuel pump may fail causing the engine to stall and not restart. Our technicians recommend replacing the fuel filter every 30,000 miles to help prevent undue strain on the fuel pump.
Overheating and/or Coolant Loss Due to Leaking Quick-Connect Fitting
The quick-connect fittings for the heater hoses tend to leak engine coolant. This problem commonly occurs because the metal housing has become brittle, which can break and cause leaks.

GMC 1500 Pickup Stories
Bought my '98 new and have put 249k fairly trouble free miles on it. Ditto on the fuel pump - lost mine 1500 miles from home and paid the price. Ride is uncomparable - I ordered a decked out 2wd with 5.7 and tow package and sound system - better road rig than a Caddy! Going to keep it for some time to come - better than a new one.
love this truck,had a few basic repairs,but engine and transmission have been awesome.
I love my truck! These trucks really are pretty rock solid, but it IS necessary to service these vehicles on time and with quality fluids and parts. The biggest problem areas with these trucks that I have found are the fuel pump, intake manifold gaskets, A/C compressor, inner and outer door handles, and maybe I'll throw in the distributor but that's not really a big deal as long as you are getting your tune up done around 100,000 miles. The fuel pumps seem to like to fail around 100,000 mile, so if you have a truck of this vintage, from a few years back to a few years newer, with the original pump with over 100k on the clock, start saving up. The fuel pump alone, (for a quality pump), is generally around $500 - $700.
diz truck is just like mine and fuken bad ass
great trk lots of miles 305 engine never a major problem
