Hello I have a 1998, 3.3L 4x4 auto. 170,000 miles. My wife filled gas tank one day last week while it idling and it started acting like it was missing after that. She drove it 200 miles through the mountains and got it home. No codes. I opened the gas cap, that looks good, and the tank depressurized for no kidding, 5 to 6 minutes. At first it was heavy and wet fumes coming out, then eventually faded away. No visible leaks anywhere, or damage. I loosened the gas cap and drove it for 18 miles. No change. Acts like it's mildly missing. Plug and wires only 1 year old. No codes. Also, the RPM gauge shakes about 200 RPMs when it feels like it's missing. Any ideas? Do ya think my ignition coil just happened to go bad at the same time? Would that not toss a code? Much thanks!

That’s because the vapours are not being captured or vented when filling up with gas. The vapour travels up the filler hose and clicks the pump off.

I replaced a sticking EVAP Purge valve. The new part, I assumed was good, stuck too. The replacement valve was defective! This caused quite the wild goose chase hunting down the "Large EVAP Leak".

If your having a problem only while filling up the tank it usually means your charcoal canister is clogged & needs to be replaced...the purge valve solenoid on the engine only works during certain conditions while the engine is running...if you've already replaced the canister & are still having the same refueling problems, I would take a look @ the lines running to it👀 Maybe have a smoke test performed 💨

The valves should come in the box closed try blowing through the inlet hose and if you can’t blow through it that’s good means the valves closed now the next steps pretty easy take a 9 volt battery and some wire and hook up the valve to it if it opens and you can blow through it the valves good.

[@xtc___3027]

@@LeadDownRang3 did replacing the valve fix it?

[@ryans413]

The reason this happens is because when gas is hot like in the summer it gives off more vapour and if the purge valve is stuck closed it can’t be burned off by the engine so it starts to suffocate the fuel pump and the pump starts sucking vapour not liquid and it stalls the engine. This usually happens with less then half a tank of gas.

[@MowSow]

@@ryans413 I’m not sure what you mean by suffocate the fuel pump and it start sucking fuel vapors, the fuel pump is always submerged in liquid and sucks fuel from the bottom of the tank, so there is no way for the fuel pump to suck vapors. If the purge valve is stuck closed, the vapors will simply vent to the atmosphere from the carbon canister through the vent solenoid. The issue with summer stalling is the purge valve stuck OPEN not closed, as it is constantly bringing in fuel vapors to the intake, it’s worse when the tank gets empty, as more vapors accumulate above the fuel. When the vapors gets into the intake from a defectively open purge valve, it causes the car to stall as it’s displacing oxygen (air) and suffocating the engine as there isn’t enough air to burn the fuel.

What's the difference between a purge valve and a EGR valve??

[@aboaniss-8590]

Egr= exhaust gas recirculation It is literally recirculating your exhaust gasses to reduce emissions and save gas But on the other side The purge valve controls the flow of the fuel vapor that is in the gas tank to benefit from it by making the car rich if the air to fuel ratio needs to.

So a purge valve that gets stuck open doesn't always cause an error code? My car has trouble idling mainly on a cold engine and I've tried almost anything else like ignition parts and vacuume leaks. I got curious because I saw this EVAP system is also connected to the vacuume hoses. The motor runs like it's on 3 cilinders when cold and idling, but when I drive it seems pretty much okay. Can I test this in a simple way?

[@vossenspringer]

@@Clean-N-ShineInDfw I dont think it is the problem in my case, took out the valve and closed off both hoses to test...I assume this mimics the situation of a perfectly closed valve and I also assume the valve is not open when idling with a cold engine normally...

[@ryans413]

@@vossenspringer the valve hardly ever opens it only opens when the EVAP canister is full. Then the canisters vapour is dumped into the engine to be burned. You should not have a rough idle on a cold start because the engine would be in open loop and running off a set program in the computer once closed loop happens the engine takes feedback from the sensors all over the vehicle. Rough idle on cold starts could be the Idle Air Control Valve. Getting stuck and not fully opening when cold. This is what controls the idle when not pressing the gas pedal and it’s job is to slowly close and bring the idle down once everything starts to warm up.

@@ryans413 Thanks for answering my question, my rough idling was fixed in the end by adjusting my valves, they were in desperate need of that....Problem was that in the past they told me the valves didn't need adjustment in my car, that it had hydrolic valves that can't be adjusted...thats why I never looked at that before, and the first 3 mechanics who looked at the problem didn't have a clue either. Luckily I finally went to an LPG garage that knows what it's doing and had it fixed...

It’s not a bad idea to change the PCV valve too both the EVAP purge and PCV valves can cause these symptoms too

I know this is for p0410…. But I need help with P0455 large leak in secondary air system. Would this part cause this code? I have the same identical truck v6. I have changed the vapor canister, fuel filler line, gas cap, secondary air pump and relay. I am still getting the P0455 code. I did a smoke test and it confused me more. I am hoping someone can guide me on what to do next. I recorded the smoke test and can send it if it would help me further. Thank you all and great video

Was you able to find the reason? Thanks in advance
