Hello
The
engine and the automatic transmission in this vehicle are computer
controlled and in most cases when a fault occurs a fault code is
stored in the memory of the computer control module. There are
exception to this, such as the Mass Airflow Meter and fuel pressure
problems. What must be done is to have all the basic testing done
such as a scan of the system for fault codes as well as a check with
a live data scanner tool for engine functions that are not within
range of normal, a trained technician is required to know what is
correct and what isn't, then based on careful diagnostics done from
a factory repair manual the correct part is replaced or the wiring
repaired or the computer replaced (known as the PCM), which is very
rarely the problem. Other basic checks must be done as well such as
mechanical problems with the engine as well as engine state of tune
and mileage on the engine. The transmission can have mechanical
issues as well such as no gear engagement at all or a filed pump or
other pressure related problems.

Cant find my oil pressure
you'll need to remove the doghouse, the cover over the engine in the passenger compartment. Sometimes you have to remove one of the front seats to get it out.
The oil pressure switch/sending unit will be just to the drivers side of the distributor. I’m happy to assist further over the phone at

How do i replace the orifice filter of 2001 chevy express 3500
The AC orifice is a metered hole has a screen filter and it should never need replacing unless the system has some kind of failure like a compressor that is coming apart and piston fragments are getting into the orifice. The Orifice is located at the inlet tube to the AC Evaporator core on the firewall on the passengers side on most GM cars and trucks.

1999 chevy express wiper stay on when wiper switch off replace motor it still runs
the only solution for that is to check your switch. Using your electrical tester when the switch is in off position check connectivity in ohms, if there is a connection it means faulty switch. Replace the switch. If the switch is ok then check the wiring going to the motor, the wire might be grounded. what i mean is that something bypass the connection, when you find it just take it out or cover it with electrical tape or insulation to cover open wire.

Chevy express 1999 didn't start, i have a code p1336. i've change the crank shaft sensor but it didn't strat and i have a P1336 code again
Trouble Code: P1336
CKP Sensor System Variation Not Learned
Possible Causes:
Set the parking brake and block the drive wheels for safety.
Verify the hood is closed.
Read the trouble codes. If a code is set, refer to that code.
Start the engine. Allow engine temperature to reach at least 158?F (70?C). Then key off.
Select Crankshaft Position Variation Learn procedure on Scan Tool & start the vehicle.
Apply the brake pedal firmly and verify the selector is in Park.
Increase accelerator pedal position until fuel cutoff is reached at the test rpm (e.g., 5150). Quickly release the accelerator pedal after fuel cutoff is reached. The CKP system variation compensating values are learned when the engine speed (rpm) decreases back to idle speed and the procedure terminates.
Read the trouble codes and recheck for DTC P1336.
If DTC P1336 runs and passes, the CKP system variation "learn" procedure is complete. If not, look for other codes. If no codes are set, repeat the test procedure.
