Evap sys incomplete and gas pumping shutting off

modelageek · #1 12-10-2014, 08:07 AM

I am having an issue with the 2004 in my sig. New motor installed from an 09 a week ago. I have never driven the truck until the motor was put in so I am not familiar with any previous issue. The truck had a 5 month old current inspection sticker on it when I bought it with the bad engine(timing chain failure) I have driven it for about a 6 days and 300 miles. The evap system will not complete. I have no codes. I also noticed that the gas station pump will shut off when filling the tank. I have to fill it slower to keep it from shutting off. my guess is that the 2 are related. It's been pouring out for 2 days so have not had a chance to look it over very well. I did look under the hood and the hose from the Tb to the solenoid on the drivers fender is connected along with the hose that runs to the back of the truck from the solenoid. I own an air compressor if needed. all thoughts are encouraged.

You need to find someone with a scan tool that can do an evap test for you

could be a problem in the filler neck

I inspected the filler neck and vent and it looks fine. The truck sat around for a total of about 3 months in the summer/fall. Maybe some spiders got in there. I will blow out a few hoses and see if that helps. I am waiting to see if it throws a code. I imagine eventually it will.

I would imagine it is something in that area, especially with the gas blocking up

Somewhere in my travels some time ago, I remember reading about a guy having this problem (can't fill fuel tank at a normal, reasonable fill rate, gas blows back out and pump shuts off, repeat, repeat, etc). Turned out it was a problem with the EVAP canister. Either here or on TRS, there is a how to and either pics or a video showing how the guy opened the canister and did a fix. At the time I didn't focus on the details, only the issue and the general solution. Maybe this will inspire someone who has been through it to speak up..............

*Could be a youtube vio showing the canister fix (?).

**Edit: the guy who did the write up was working on a Ranger with the newer style canister. Buy that I mean the long, rectangular one up by the spare tire and not the old setup with the small canister under the hood and down low.

Anyone know the best way to disconnect this hose (with the yellow clip).

cowboybilly9mile · #8 12-13-2014, 11:40 AM

There's probably a fancier way, but I use a small flatblade screwdriver or a medium jewelers screwdriver and push/poke/gently pry on those then pull to separate the connection. Looks like the same style connector as used on the fuel filter.

Got it off using a pair of channel locks poc. Blew out the evap hoses. See if that helps.

modelageek · #10 12-17-2014, 01:20 PM

I removed the filler vent and blew air through it. I also removed the hose at the canister and blew air through that. It seems to fill up better now. Only stopped once out of 3 refuelings. The system is still not ready and there are no codes after 600 miles. What could keep it from completing but not throw c odes? Hmmm?

Our work vans do this from a blocked or dirty filter for the evap system. Don't know if its the same set up our work vans are Chevys. But as soon as they change that filter works just like new.

Setting the evap monitor on a Ranger is a PITA. Mine STILL hasn't set after replacing my battery well over a month ago.

You have to have a bunch of conditions met to the LETTER in order for it to set.

Here's the exact procedure.

Quote:

The following procedure is designed to execute and complete the evaporative emission repair verification drive cycle and to clear the Ford P1000, Inspection And Maintenance (I/M) readiness code. When the ambient air temperature is below 4.4°C (40°F) or above 37.8°C (100°F) , or the altitude is above 2,438 meters (8,000 feet) , the EVAP monitor will not run. If the P1000 must be cleared in these conditions, the Powertrain Control Module (PCM) must detect them once (twice on some applications) before the EVAP monitor can be bypassed and the P1000 cleared. The EVAP bypassing procedure is described in the following drive cycle.

Drive Cycle Recommendations
Most OBD II monitors will complete more readily using a steady foot driving style during cruise or acceleration modes. Operating the throttle in a smooth fashion will minimize the time necessary for monitor completion.
Fuel tank level should be between one-half and three-quarters full with three-quarters full being the most desirable.
The evaporative monitor can only operate during the first 30 minutes of engine operation. When executing the procedure for this monitor, stay in part throttle mode and drive in a smooth fashion to minimize fuel slosh.
NOTE: For best results, follow each of the following steps as accurately as possible.

Drive Cycle Preparation
Install the scan tool. Turn the key ON with the engine OFF. Cycle the key off, then on. Select the appropriate vehicle and engine qualifier. Clear all Diagnostic Trouble Codes (DTCs) and carry out a PCM reset.
NOTE: This step bypasses the engine soak timer and resets OBD II monitor status.

Begin to monitor the following PIDs: ECT, EVAPDC, FLI (if available) and TP MODE. Press Diagnostic Data Link, PCM, PID/Data monitor and record, press trigger to select each PID, then start.
Start the engine without returning the key to the OFF position.
WARNING: STRICT OBSERVANCE OF POSTED SPEED LIMITS AND ATTENTION TO DRIVING CONDITIONS ARE MANDATORY WHEN PROCEEDING THROUGH THE FOLLOWING DRIVE CYCLE.

Preparation for Monitor Entry
Idle the vehicle for 15 seconds . Drive at 64 km/h (40 mph) until the ECT is at least 76.7°C (170°F) .
NOTE: This step allows engine warm-up and provides Intake Air Temperature (IAT) input to the PCM.

Is IAT above 4.4°C (40°F) and below 37.8°C (100°F) ? If not, continue with the following steps but note that the EVAP Monitor Bypass portion of the drive cycle (step 13) will be required to bypass the EVAP monitor and clear the P1000.
Cruise at 64 km/h (40 mph) for 60 seconds .
NOTE: This step executes the Heated Oxygen Sensor (HO2S) monitor.

Cruise at 72 to 104 km/h (45 to 65 mph ) for 10 minutes .
NOTE:
This executes the EVAP monitor if IAT is above 4.4°C (40°F) and below 37.8°C (100°F) .
To initiate the monitor, TP MODE should equal PT, EVAPDC must be greater than 75%, and FLI must be between 15 and 85%.
Avoid sharp turns and hills.
Bring the vehicle to a stop. Idle with the transmission in DRIVE (for automatic transmission) or NEUTRAL (for manual transmission) for two minutes .
NOTE: This step executes the ISC portion of the Secondary Air/CCM.

Pending Code and EVAP Monitor Bypass Check
Using the scan tool, check for pending codes. Conduct normal repair procedures for any pending code concerns. Rerun any incomplete monitor.
NOTE:
This determines if a pending code is preventing the clearing of P1000.
If the EVAP monitor is not complete and IAT was below 4.4°C (40°F) or above 37.8°C (100°F) temperature range in Step 8, or the altitude is above 2,438 meters (8,000 feet) , the EVAP Monitor Bypass (Step 13) must be carried out.
EVAP Monitor Bypass
Park the vehicle for a minimum of eight hours . Repeat Steps 5 through 12.
NOTE:
This allows the bypass counter to increment to two.
Do not repeat Step 4.

Thanks. I will give this a shot and report back!

SUCCESS!

Thanks for the help . I reset the puter with my scanner and let it sit for 2 days. Then over the next week I made a few 20 mile highway trips starting from a stone cold truck following the precedure the best I could. My IAT never was above 40F. Just today on about the 4th trip the evap system completed. Waiting on line as we speak to get the truck inspected.

Thanks again!

No problem. I need to hook my truck to see if the damn monitor has finally set on mine.

However, my emissions aren't due until October of 2015 and my truck will pass emissions with 1 monitor not set. So.....don't really care.
