If the pressure is slow to rise, you should consider changing the fuel filter if it has not been done in the past 30,000 miles.
Next, disconnect a spark plug and check for spark while engine is cranking. Use a spark tester or old spark plug grounded to the engine block.
Let me know.
Regards,

SOURCE: The air conditioning blows only hot air

Is that your static pressure readings??? If that is your static pressure readings that's good. When the engine running and fan on high and a/c compressor clutch engaged you should have 25 to 35psi on your low side and 200 to 350psi on your high side. If the clutch is engaged and that is your readings, replace your a/c compressor. Keep me posted, be glad to help.

SOURCE: pressure on low & high side reads 110 psi and wont charge

Check the exspansion valve its part of the evaperator on that car for being clogged.

SOURCE: air conditioning compressor will not kick in,

If it is above 100PSI, you are over charged. Any thing under, should be normal to low. You probably need to get it checked by a professional to make sure it has the correct charge, and the compressor is getting power when the switch is turned on.

If the fuel pump(s) run while the pressure is falling, replace the fuel pressure regulator and (although I'm sure you've already done this), replace the fuel filter. If the fuel pumps appear to be turning off by themselves, replace the inertia (fuel cutoff) switch.

What is the high pressure reading for charging freon for the air condition?


For charging purposes, you really should be monitoring the low side pressure. Depending on ambient air temperature, the low side should be between 30 and 50 lbs PSI. The high side can be between 135 and 330 lbs PSI.

2005 Lincoln Town Car suffering from low fuel pressure, I have Changed Fuel Rail pressure sensor, Fuel Pump driver, the fuel pump in the tank and the fuel filter but it is still showing only 26 psi fuel...


The ford spec listed in the ford engine control manual is:

General Specifications Item Specification Fuel tank capacity 71.9L (19 gal) Fuel Pressure Hot restart 448-482 kPa (65-70 psi) Key ON Engine OFF (KOEO) 140-415 kPa (20-60 psi) Key ON Engine Running (KOER) 170-280 kPa (25-40 psi)

Are you measuring the fuel pressure with a mechanical gauge or are you using a scan tool . If with a mechanical gauge, does the gauge have an air purge? What symptoms does the vehicle present. If running rough you could have a fuel injector leaking. Are you measuring the fuel pressure with the key on engine off? If so, did you cycle the key a few times? Good luck

Where is the a.i.r. pump located



The air pump for the secondary air system (emission control device) is located under the battery. If you do replace it, replace the check valve too, it is on top of the exhaust manifold and connected to the pump with a hose. The check valve fails and ruins the pump. Source(s): http://repairpal.com/volvo-850-1997/comm…
http://repairpal.com/air-pump-check-valv…
http://repairpal.com/air-pump

OR


I think they are talking about the pump to provide vacuum to the climate control when the turbo is putting boost in the intake manifold. The vacuum can come from an electric pump or from an engine driven pump, something like an old engine driven fuel pump. I needed an electric pump for my 765T, and all the wrecking yards wanted to sell me the engine driven form. (A new one was $500, and it wasn't that important to me.)

An engine that takes the engine driven pump will have a hole in it while the others will not have a hole. Source(s): 35 years maintaining my own cars, including 17 years with a 1985 765T

Automatic Level Control System Operation Check
Support the rear wheels or support the rear lower control arms when certain tests require raising the vehicle on a hoist. Use two additional jack stands in order to support the rear lower control arms in the normal curb weight position when a frame type hoist is used. Refer to Trim Height Specifications in Suspension General Diagnosis.

Refer to ALC Suspension System Check for electrical troubleshooting of the Automatic Level Control (ALC) system, or if DTC's are present.

Diagnosing Leveling Complaints Without DTCs Present Procedure
Perform the following preliminary inspections before performing the system performance test:

Inspect the ignition (pin A & pin H) at the ALC sensor connector.
Ensure that the ignition (pin A & pin H) at the ALC sensor connector connection is secure.
Inspect the ground (pin E) at the ALC sensor connector.
Ensure that the ground (pin E) at the ALC sensor connector connection is secure.
Inspect the ALC sensor link.
Ensure that the ALC sensor link is properly secured to the actuator arm.
Inspect the ALC sensor actuator arm for damage.

Air conditioner in 1999 mercury tracer won't work. It's not the compressor nor does it have a leak. what could be the problem?


the tracer is the same as the ESCORT, right?? TRY THIS--I WORK ON PLENTY OF ESCORTS--LOOK UNDER THE AIR CLEANER/CONE ASSEMBLY--THERE WILL BE A BLACK METAL BOX(FULL OF RELAYS) ONE OF WHICH IS THE A/C RELAY--TRY TAPPING ON IT WITH A LONG SCREWDRIVER OR SOMETHING SIMILAR WHILE U HAVE THE A/C ON. IF THE A/C SUDDENLY STARTS WORKING U NEED TO GET A NEW RELAY BOX(I THINK ITS CALLED A GEM MODULE) i do have a question- does the blower motor work?? how do u know the compressor is good??do you have 12 volts going to it??? this relay box is pretty common to go bad--u have to remove the air cleaner in order to get to it.get back to me.

Where do I recharge ac at


there are 2 ports one for low pressure and one for high pressure. the low pressure is bigger in diameter and is usually close to the dryer and or fender and firewall. the high pressure is near the condensor on the fron of the vehicle. if there are caps for the ports low will be blue and high will be red. low side pressure should be 35-50 psi and high pressure should be 135-150 psi
