Vent Control Solenoid/Evap Solenoid

[bluedragon436]

A little late maybe.. But the only valve I know of is the purge valve solenoid which is the one under the hood... I will say if you decide to replace that one, to see if it helps your issue... order it from Rock Auto... not only because they are a vendor here... but because it's like 25 roughly, compared to like 40+ at local auto parts store... even with the shipping it was way cheaper than I could find locally... As far as the gas pump kicking off.. is it doing it like as soon as you start filling, or towards the end of the tank being almost full (just earlier than it should, like before it is really full)??

As a follow up to two problems that have plagued me for over a year in the case of low fuel pressure more than two years.

Few years ago I was having trouble starting, had to do the double key on thing to get started.

I checked fuel pressure at the fuel rail and found that the fuel pressure dropped almost immediately upon shutting motor down. I suspected a bad check valve in fuel pump. I changed the entire pump assembly.

While I had the old pump out I thoroughly washed,rinsed,and allowed the fuel tank to dry.

I put everything back together and I found I still had the same problem.
I took defective pump back for exchange (which was pain free) installed a new pump (different brand).Same problem.

Thinking it must be a leak somewhere in line between pump and fuel rail. Also put in fuel injector mod.

Now I also had a problem with gassing up, gas station pump would stop every couple of seconds. And threw evap. system code, I worked with these two conditions for over a year trying to trouble shoot leak.

Finally bit the bullet and bought a brand new pump.

After I removed the pump I reached into fuel tank and found what I believe to be a combination rollover valve and vent valve The mechanism had come loose (ping pong ball with a spring in a cage) II guess had come loose with I was washing tank. t was now seating right. Put pump back in. Now every thing is working as designed. Pressure runs at approximately 50 psi when motor running Key Off the pressure drops to 14-30, but still holds enough fuel at rail so that so you get instant an start. Hope this helps someone. Time for me to screw something else up.Thanks everyone for your help,.
