2001 GMC Safari Questions & Answers
When starting the van some times it works and some
If ignition and spark seem to be ok, it's time to look at your fuel system. When you say "turns off", if all electrical power seems OK, check the fuel pressure for faulty pump, plugged filter or faulty regulator.
@001 GMC Safari, No fan for A/C or heater, lights
Fusible link is in the main battery 12v wire somewhere between the battery and the fuse block. However, if that blew, the truck will be dead. I really depends where the lift wire was connected, and as you pointed out, that is bad as it may have burned out the wire it's connected to - focus on that connection and the other systems on it.
2001 GMC safari engine noise- sounds low,
not a bearing problem as they get noisier under load or rpms , not quieter
oil pressure always drops around 10% of full pressure at idle more if the oil is of low viscosity ( 5w10 or 15) use a mechanic stethoscope to determine noise source at idle
A/c control for dash
If you only get air blowing from the defrost & foot level vents check & replace the hard plastic vacuum lines under the hood with rubber vacuum line. That will fix your problem
Need to reset the BCM - How can I do that?
Disconnect the battery + for 15 minutes then turn the key forward and back off re connect the cable and that will reset the BCM. Dont know if it will fix problem but good luck!
Have dutch doors on a
If the actuator is working (You hear a "click" when you turn the key), one of the rods may have come disconnected from either the actuator or the latch. You will have to remove the upper door interior panel to gain access to these parts. If you are VERY careful, you may be able to remove it without damaging it, but you may end up having to get a replacement panel (Try your local salvage yard). The rods come from the factory with a plastic clip holding them into the socket. These deteriorate over time and allow the rod to pop out when the hatch is closed (Especially if it is slammed). Once you have the door open, you can reconnect the rod using a clip like the one pictured below, or by using a piece of "safety" wire attached through existing hole in the door panel to keep the rod in place. Hope this helps!

P1335 CHEVROLET
P1335 CHEVROLET - Crankshaft Position Circuit
Possible causes
- Faulty Crankshaft Position Sensor
- Crankshaft Position (CKP) Sensor harness is open or shorted
- Crankshaft Position (CKP) Sensor circuit poor electrical connection
Help with this
Symptoms
- Engine Light ON (or Service Engine Soon Warning Light)
- Lack/Loss of Power
- Engine Stall
P1335 CHEVROLET Description
The Crankshaft Position (CKP) sensor sends pulses to the Powertrain Control Module (PCM) as the reluctor wheel teeth rotate past the CKP sensor. The PCM uses the CKP pulses to synchronize the ignition and fuel injector operation, and to time the interval between each CKP pulse. The PCM determines when an excessive change in crankshaft speed occurs by comparing each new time interval with the previous interval. A misfire causes an unexpected change in the crankshaft speed. A certain amount of acceleration/deceleration is expected between each firing stroke, but if the crankshaft speed changes more than an expected amount, the PCM interprets this as a misfire. The interval between CKP sensor pulses is extremely small. At high engine speeds, slight variations in the following components make misfire detection difficult:
- Crankshaft
- Reluctor wheel
- CKP sensor
The PCM learns variations during the Crankshaft Position System Variation Learning Procedure. The PCM compensates for these variations when performing detect misfire calculations. Only a scan tool can command the PCM to perform the Crankshaft Position System Variation Learning Procedure again.
Perform the learning procedure after the following actions:
- A PCM replacement
- Any operation or repair involving the crankshaft, the CKP sensor, or the CKP sensor to reluctor wheel gap relationship.
- An engine replacement.
- The ignition switch is in the ON position until the battery is drained.
