Not at all, it has absolutely no connection. If in doubt better change the relay first than changing the fuel pump, its cheap.

I googled this for you: What does that mean? The Evaporative Emissions System (EVAP) allows fumes from the gas tank to enter the engine to be burned, rather than vented into the atmosphere as an emission. The purge valve solenoid is supplied switched battery voltage. The ECM controls the valve by operating the ground circuit, opening the purge valve at specific times allowing these gasses to enter the engine. The ECM monitors the ground circuit as well, watching for faults. When the purge solenoid isn't activated, the ECM should see a high voltage on the ground circuit. When the solenoid is activated, the ECM should see the ground voltage pulled low, close to zero. If the ECM doesn't see these expected voltages, or senses an open in the circuit, this code is set. Potential Symptoms P0443 trouble code symptoms could be just an malfunction indicator lamp (MIL) illumination. There may be no drivability problems at all. But, it's also possible to have a lean condition or a rough running engine if the purge valve is stuck open. Usually though, these symptoms are accompanied by other EVAP codes. Another symptom may be excessive pressure in the gas tank in the form of a "whooshing" sound when the cap is removed, indicating a purge valve that isn't working at all or stuck closed. Causes To cause a P0443, there has to be a problem with the purge control CIRCUIT, not necessarily the valve. Usually they are a unit housing the valve and the solenoid as an assembly. Or it could be comprised of a separate solenoid with vacuum lines to a purge valve. That said, it could be any of the following: * Bad purge solenoid (internal short or open) * Wiring harness chafing or rubbing another component causing short or open on control circuit * Connector worn, broken or shorted due to water intrusion * Driver circuit inside powertrain control module (PCM) is bad Possible Solutions 1. Using a scan tool, command the purge solenoid to activate. Listen or feel for a clicking coming from the purge solenoid. It should click once, or on some models it may click repeatedly. 2. If it doesn't click with scan tool activation, unplug the connector and examing the solenoid and connector for damage, water, etc. Then check for battery voltage on the feed wire with the key on. If you have battery voltage, then ground the control side manually using a jumper wire and see if the valve clicks. If it does, then you know the solenoid is working properly but there is a problem with the control circuit. If it doesn't click when you manually ground it, replace the purge solenoid. 3. To check for a problem on the control circuit (if the solenoid tests okay and you have voltage to the solenoid) plug the solenoid back in and remove the control circuit (ground) wire from the ECM connector (If you're unsure how to do this, do not attempt). With the ground wire removed from the ECM, turn the key on and then manually ground the Purge valve control wire. The solenoid should click. If it does, then you know there is no problem with the control wire to the solenoid and there is a problem with the ECM purge solenoid driver circuit in the ECM. You'll need a new ECM. However if it doesn't click, then there must be an open in the wiring between the ECM and and the solenoid. You must find it and repair it.

i have this 2001 commander since 2 months and i wanted to know when do i need to changed the fuel filter.

the car had a sudden loss of power after 10 min of starting and came back to life after 3 self. why did this happen

when changing the fuel pump do i need to replace the relay as well? thanks

Recently, my malfunction indicator light came on and i was told that it is evaporation emissions system failure. these guys are charging me bomb to fix it and i would like to know before i spend my money what dose this mean. thanks

Check the pads and drum for sure. But your problem more likely is the brake booster getting weak and aged.

Have you filed with ATF III? If yes then you need to steer steering left and right for filling the pump fully. Check the PSF level and if its low top up and it will stop the noise.

my break pads have to go long way before they engage and almost halfway to the ground for a complete stop any idea on this

after replacing the power steering pipe and refilling the fluid the pump got noisy. what happened

Its a clear indicaton of low AC gas, Check for leak from O rings in the nozzle and refill the AC gas with little AC oil.

They are located near the front bumper behind the grill to one side of and below the radiator. Look for a small black cylindrical object with two wires coming out of it.

Please dont do drive with Engine oil light on Your engine oil pump has failed and many components inside engine is running dry. May be the damage is already done or it will happen soon after you fix new pump. If you hear clanking noise from engine then that means crank main bearing or crank connecting rod bearing is fried due to heat as oil lubrication was missing. It will be very unlikely if bearng are still fine. Only if as soon as you seen this engine oil light and stopped the vehicle.

You know both route and its upto you to choose. Both routes cost almost same if you rebuild or get used one. I choose to rebuild so to be 100% sure that i have almost new like engine after spending 4k-5k.

my AC keeps switching on and off very fast not that the car is heating up or anything nor is there an issue of the compressor then what

May i please have the location of ambient air senor and the procedure to replace it in 1997 cherokee. thanks

my 2001JGC is getting a check gauge light come on so i changed the oil pressure sensor and still the light stay on i got all the oils changed and now i dont know what to do.

my wrangler's engine froze due to low engine oil, i unfreezed it but its not the same. it knocks badly and is in very bad condition. is it advisable to rebuilt it and install the same or do i get a new one and get rid of this. thanks

Its a 60AMP blue color fuse on center bottom.

Get dobinsons for 500 / pair Ranchos 800/ pair Rough country 350/pair

Desert rides usually have that, its quite common problem. Get red color can of Carb Cleaner (Carburetor) and put some generous amount on O2 chip and it will help if not solve 100% problem atleast it will make difference of about 75% change in O2 sensor performance.

Thats a nice find dude. Good work and thanks for sharing, really appreciate it.

Engine fan approx 400 - 600 dhs Fuel pump is around 300 - 500 dhs Depending on which year, older year are cheaper and newer than 2007 is slightly expensive.

can somebody please tell me where is the fuse for alternator located in 1999 Cherokee? thanks

which shocks are the good and not very extravagantly expensive for my 2003 Liberty??????
