FJ62 - Hard Start & Gas Smell After Shut Off

[SAR_Squid79]

Posting this from MUD to TTORA to maybe help someone out.

This problem started very suddenly on Thursday...

First off, for a few weeks now, I've had a check engine light.
Codes:
25: - Air Fuel Ratio Lean Malfunction
26: - Air Fuel Ratio Rich Malfunction

I thought it was the o2 sensors, but just haven't got around to replacing them yet, as the Cruiser still ran fine. About 6 weeks ago, my Fuel Pump died, and I replaced it, everything was good to go . . . a couple of weeks later I got the CEL . . . now this.

Thursday morning, my Cruiser started up just fine; 1 turn of the key as usual. At lunch time it started fine, I went out to eat lunch, then after lunch it was a little hard to start (had to crank it over 2 good times). Once it's started, it runs just fine. As smooth as always. After you cut the truck off, you can smell a very strong gas smell. It seems to be coming from the driver's side of the engine bay. Now every start is hard - it has to be cranked over 2 or 3 times to start, and gives off the strong fuel odor after every shut down.

At first, I was thinking that maybe the Fuel Pressure Regulator is where I should start. The FPR seems to be problem child for lots of different problems on the FJ62s. The FSM also mentioned some kind of Check Valve... And on IH8MUD, I read a lot about a fuel pulsation dampener being the problem for a lot of guys. I had never even heard of such a thing before.



Upon further inspection and troubleshooting this morning, I have confirmed that this Fuel Pulsation Dampener is definitely the culprit. It's dribbling gas, and is definitely source of my problem! IH8MUD saves the day again - because I doubt if I would have ever found that little son of a bitch on my own. I think it's wierd that this part could have gone bad and started leaking so suddenly... Maybe it'll make more since once I get it off the truck, and can look at it closer.

Now I just have to figure out where to get a replacement. I can't find any reference to this part in the FSM, so I don't know if "Pulsation Dampener" is the actual nomenclature, or what...

After doing a little searching - maybe Toyota Part Number: 23207-74010?

I snapped a couple of pics of this pesky Pulsation Dampener - maybe it'll help somebody out in the future. This thing is hard to find, hard to see, and is definitely going to be a PITA to get a wrench on.
