1. Pressure switch: The pressure switch may not be shutting off the compressor when it reaches the set pressure level. If this is the case, the switch will need to be replaced.
2. Check valve: The check valve prevents the compressed air from flowing back into the compressor pump when it is not running. A malfunctioning check valve can cause pressure to continue to build up, even when the compressor is idle. A damaged or worn-out check valve may need to be replaced.
3. Piston rings: If the compressor's piston rings are worn or damaged, air can leak past the piston and cause pressure to continue to build even when the compressor is idle. In this case, the piston rings will need to be replaced.

your anti theft device is activated,you need to lock and unlock your doors a couple times with the key fob,not the key,and then you need to put the key in the ignition and start it,if you dont have your key fob,call your car dealer to get a new one,they are programmed for each car only,you cannot bypass it.

Get the codes read. It sounds like a crank position sensor

Just lock and then unlock the drivers door lock with the key.

Setting a code P0322 for missing or erratic 4x reference signal. Also experiencing long crank times. Tests/Procedures: 1. Check for an erratic signal from one or both of the CKP sensors. 2. Check for a square wave signal at ignition module on the Purple/White wire. 3. Verify the wiring from the ignition module to the Powertrain Control Module (PCM). P0322 ICM 4X Reference Circuit Malfunction - With Automatic TransmissionPossible Causes Setting Conditions •Fuel control signal circuit is open •Fuel control signal circuit is shorted to ground •IC module has failed •PCM has failed DTC P0340 and P1376 not set; engine running; CMP sensor signal detected in the last 4 seconds, and the PCM did not detect any 4X fuel control pulses for 4 seconds. This code sets in 1 Trip(s).

You may need to bleed off the air in the gas line.

The link below is not exactly like your compressor but will give you an idea of how heads are assembled. If gaskets need replacing try making them out of automotive gasket material or use the metal from aluminum soda/beer can. If you need to replace a reed valve, make it out of feeler gauge material. The reed valve needs a little wiggle room to work, try to use gasket material of same thickness. There are two chambers in the head (upper most part), one chamber is intake the other is exhaust. The intake valve is usually slightly cleaner looking than exhaust valve (exhaust valve gets hotter, looks burned) and exhaust chamber in the head is usually darker sometimes oily. Intake reed is closer to piston. Exhaust reed is closer to top of the head. http://www.ereplacementparts.com/campbell-hausfeld-dp400000av-2005-air-compressor-pump-parts-c-32345_32355_33008.html

Perdon, soy Mexicano pero no se practica el espanol. Asi es que voy a darle un explicacion en Engles. Check for suction at the intake. If the compressor is pumping air, there will be good suction. If you do not feel suction or air is seemingly coming out of the intake, most likely the valves /gasket are faulty (remove the head/heads and replace parts as needed). If there is good suction at the intake, then most likely air is leaking out of system(check all connection with soapy water) .

Tap the bolt of the puller while you tighten it, spay some penetrating oil on the shaft and leave it for a while and try again. If that is unsuccessful, apply a little heat to the flywheel and try the above again.

First, how much pressure are you at when it is going off? If it is high pressure, this is a serious and potentially dangerous situation. the pressure relief valve is a safety release to keep it from blowing. If it is at low pressure it would be rare for a PRESSURE RELIEF VALVES have to have a real problem. Check to make sure it is seated properly. Often there is a round wire on attached to make a handle for manual release. If this gets hung up on surrounding parts or twisted it might set the valve on the pinnacle of release.

If you remove the motor cover or small
plate,on the back of it or on the outside of the
motor case on the label,you should see the
connections for either voltage

You always want to use the 240 volt, to save electric,
and wire a 1900 box and duplex for it

It should, by code be on it's own circuit

Line one and two is what you use for 240
and there should be others you move for
that choice
