P0320 99 WON'T START WHEN HOT

1999 Ford Windstar

Engine Performance problem
1999 Ford Windstar 6 cyl Front Wheel Drive Automatic 200000 miles

I have a 99 windstar. It will die while driving as if the ignition key was turned off. It did bring on the check engine light with a P0320 code. It will start up and run again after I wait 2-3 hrs for the whole engine to cool down, then it might die again after 5 miles of driving. I erased the code after I installed a new crankshaft sensor. It ran fine for a day then it all happened over again without bringing on the code this time. Next I changed the coil pack. It ran again, but now is still dying out while driving down the road and won't start unless it is allowed to cool down for 2-3 hours. The code has not came back after the first time.

They are asking me to check voltage across a set of wires that I just disconnected, OHM's yes, voltage can't do it. I guess they want to see 5 ohms from the PCM to CKP sensor wiring while both the CKP and PCM are connectors are disconnected.

Yeah don't make sense? Unless you plug it back in. But then stage 2 say's plug it back in? We have already checked the condition of the pins. So plug it back in a test it that way.

I bought a PCM from that ebay seller I offered $100 and he accepted. I figure that getting voltage of 1.7 VAC while the engine is turning tells me the crank sensor is good and no spark at the wires means no spark issue, I am going to swap the PCM. It is all after this heavy rain we had. $100 can't go wrong. This thing is really fix or repair daily, F.O.R.D.

I think $100 is a very good price. I'll keep my fingers crossed. Cars used to run just as good without all these solonoids, sensors etc. Etc. Ha ha. Let me know how it goes please.

Happy Xmas & new year

Did you see the website for the PCM? I hope it works well. I suppose they have a good test bench for this stuff. Yes cars without sensors and stuff are more my style. I was an ASE mechanic and switched to aircraft. These computer cars are ok if you have the test equipment.

I put the new PCM in and it won't start. The guy that gave me the PCM and said I might have to do the 10 minute PATS key relearn procedure because it is a new remanufactured PCM. I either have a system A, B, C, D or E. In the PATS relearn procedure, it says to install a scan tool or the J2534 Global programer to the data link connector. How can I do this?

Sorry I have not got back to you sooner. Try these steps first. I thought the PCM would have come preprogrammed with your old data?

PROGRAMMING SPARE KEY(S) WITH TWO PROGRAMMED KEYS
NOTE: This procedure will only work if 2 or more programmed ignition keys are available and there is a need to program additional keys. If 2 keys are not available, perform PROGRAMMING TWO KEYS/ERASE ALL KEY CODES. Instrument cluster PID SPARE_KY must be enabled for this procedure to operate. To enable this PID, perform SPARE KEY PROGRAMMING SWITCH and enable spare key programming switch. If programming procedure is successful, new key(s) will start vehicle and THEFT indicator will illuminate for 3 seconds. If programming procedure is not successful, new key(s) will not start vehicle and THEFT indicator will flash for one minute (after flashing for one minute, THEFT indicator will flash fault code). If necessary, repeat programming procedure. If programming of key(s) is still unsuccessful, perform self-diagnostics. See SELF-DIAGNOSTIC SYSTEM. Maximum of 8 keys can be programmed into system. If procedure is not performed as outlined, programming procedure will end. Ignition keys must have correct mechanical key cut for vehicle and must be an encoded key.

Insert the first programmed ignition key into ignition lock cylinder. Turn ignition switch from OFF to RUN position (ignition switch must stay in RUN position for one second). Turn ignition switch to OFF position and remove ignition key from ignition lock cylinder.
Within 5 seconds of turning ignition switch to OFF position, insert second programmed ignition key into ignition lock cylinder. Turn ignition switch from OFF to RUN position (ignition switch must stay in RUN position for one second). Turn ignition switch to OFF position and remove second ignition key from ignition lock cylinder.
Within 5 seconds of turning ignition switch to OFF position, insert a NEW unprogrammed ignition key into ignition lock cylinder. Turn ignition switch from OFF to RUN position (ignition switch must stay in RUN position for one second). Turn ignition switch to OFF position and remove ignition key from ignition lock cylinder. The NEW ignition key should now be programmed. To program additional key(s), repeat key programming procedure from step 1.

Well, I gave him my VIN and mileage and the part #. He mailed the new one to me along with a note saying that I might have to perform the 10 minute PATS re-learn procedure to get the car to start. I think this involves having a scan tool or J2534 global programmer according to the directions. I only have 1 key for my van currently. That is the problem

What about this. How do you do it. If 2 keys are not available, perform PROGRAMMING TWO KEYS/ERASE ALL KEY CODES.

Looks like you will have to get someone to come along and reprogram for you or have the vehicle towed to a shop.? In england we had tech's who would come out and do this. But I have never had to do this here (in the U.S.) Yet. So I don't know if they even do this.I'm sure they do I will look into it and let you know?

Key Programming - Erase All Keys & Program 2 Keys
Insert Ford Service Function (FSF) card into NGS tester. Turn ignition switch from LOCK to RUN position. With NGS tester connected to vehicle, enter PCM then select SECURITY ACCESS PROCEDURE. This procedure will take 10 minutes to perform. After the security access procedure has been completed, a new menu will be displayed with command options. Select IGNITION KEY CODE ERASE.
Turn ignition switch to LOCK position and disconnect NGS tester. Insert first encoded ignition key into ignition lock cylinder. Turn ignition switch to RUN position for 3 seconds. Turn ignition switch to LOCK position and remove first encoded key.
Within 5 seconds, insert second encoded ignition key into ignition lock cylinder. Turn ignition switch to RUN position for 3 seconds. Turn ignition switch to LOCK position and remove second encoded key. Both encoded ignition keys should now start vehicle.
NOTE: Security access must be granted to erase ignition keys, enable/disable spare key programming switch, or perform parameter resets for PCM. This procedure has a 10-minute time delay prior to granting security access during which the New Generation Star (NGS) tester must remain connected to vehicle. After security access has been granted, security access command menu is displayed which offers various command options. Multiple security access commands can be executed (if necessary) prior to exiting security access command menu. Execution of all necessary security access commands prior to exiting command menu avoids the performance of an additional security access procedure and the associated 10-minute time delay.

Key Programming - Security Access Procedure
Insert Ford Service Function (FSF) card into NGS tester. Turn ignition switch from LOCK to RUN position. With NGS tester connected to vehicle, enter PCM then select SECURITY ACCESS PROCEDURE. This procedure will take 10 minutes to perform. After the security access procedure has been completed, a new menu will be displayed with command options. Select as many functions as required before exiting this menu. Once this menu is exited, security access procedure must be performed again to perform additional commands.
NOTE: The spare key programming switch is a programmable switch which provides the capability to enable/disable the normal customer spare key programming procedure detailed in the owner's manual. This programmable switch is provided as a convenience for rental company fleets or other fleet purchasers who may not want the spare key programming procedure available to the vehicle driver. The spare key programming switch state can be viewed using PCM PID SPARE_KY.

Key Programming - Spare Key Programming Switch
Insert a programmed ignition key into the ignition lock cylinder. Insert Ford Service Function (FSF) card into NGS tester. Turn ignition switch from LOCK to RUN position. With NGS tester connected to vehicle, enter VIC then select SECURITY ACCESS PROCEDURE. This procedure will take 10 minutes to perform. After the security access procedure has been completed, a new menu will be displayed with command options. The default setting on all new vehicles is ENABLE. Select SPARE KEY PROGRAMMING SWITCH. Set SPARE KEY PROGRAMMING SWITCH to ENABLE to allow keys to be programmed or DISABLE to make key programming not accessible.

NOTE: This procedure will only work if 2 or more programmed ignition keys are available and there is a need to program additional keys. If 2 keys are not available, perform KEY PROGRAMMING - ERASE ALL KEYS & PROGRAM 2 KEYS. PID SPARE_KY must be enabled for this procedure to operate. To enable this PID, perform KEY PROGRAMMING - SPARE KEY PROGRAMMING SWITCH and enable spare key programming switch. If programming procedure is successful, new key(s) will start vehicle and THEFT indicator will illuminate for 3 seconds. If programming procedure is not successful, new key(s) will not start vehicle and THEFT indicator will flash for one minute (after flashing for one minute, THEFT indicator will flash fault code). If necessary, repeat programming procedure. If programming of key(s) is still unsuccessful, perform self-diagnostics. See SELF-DIAGNOSTIC SYSTEM in PASSIVE ANTI-THEFT SYSTEMS - CONTINENTAL article in ACCESSORIES & EQUIPMENT. Maximum of 8 keys can be programmed into system. If procedure is not performed as outlined, programming procedure will end. Ignition keys must have correct mechanical key cut for vehicle and must be an encoded key.
