    97 FZJ80 Stumbling off idle

    Yes I did but unfortunately, I cannot tell you what worked. As the weather got warmer in the spring, the stumble continued but lightened. I learned at some point in time if I could get the revs up in neutral to about 4k by continuously stabbing the throttle to get the revs up past the fall...

    Gotta Love Prime. Cheap and quick! Just the way I like it! :D LOL Anyway, the pump and connector look darn close to stock with one exception. The spade terminals have been upgraded. Dare I say maybe the Chinese knock off company recognized a deficiency in the Toyota design?

    Chris Thank you for the confirmation. I guess at this point, if nobody else has seen this connector anywhere, I will give up looking for it and put in the $25 amazon aftermarket pump with the connector it comes with.

    It is an OEM Connector and an OEM pump. I have owned this vehicle since almost new way back in the early 2000s maybe 2002 the pump failed on me at the Yankee Toys Fall Gathering. When I replaced the pump I replaced it with Genuine OEM for a small fortune. The new pump coming out of the...

    It's not totally a "Universal" I guess I stated that wrong. Amazon states it works for 97 fzj80 and it looks pretty darn close to the original in design but it is an aftermarket part and really dirt cheap like $25. I guess what I am asking if anyone has used these aftermarket pumps and given a...

    Thank you for the post. I looked real hard at this connector and unfortunately, there were no numbers to be found. As such I am still looking for the connector. I did find many universal fuel pumps dirt cheap on amazon that say they fit the 80. They look the same and include their own...

    Since explosion is such a non-issue in there which one of you guys wants to cut off your connector and swap with me? Waiting... Waiting... I thought so.... :D

    I have heard other people say the same thing to justify placing an electrical pump inside a fuel tank. What we all need to realize that quite often the entire tank is nothing but gasoline vapors. The 25 gallon 80 tank is terribly small for a vehicle that realistically gets about 12 MPG. If I...

    So I have been troubleshooting a PO171 code for quite some time. I have searched and tried pretty much every possible cause with the exception of swapping the MAF. The latest item I checked was the in-tank fuel pump and sock. What I found will shock you. The connector to my fuel pump has...

    97 FZJ80 Stumbling off idle

    Hi Squash, Thank you for your persistence in trying to help. I did do the definitive test recommended. I removed the connector to the gauge sender located just above and to the left of the oil filter on the motor. The gauge needle dropped to the bottom dead but the ODBII feed to the Tourqe...

    97 FZJ80 Stumbling off idle

    I will also mention some things I did since I last posted. One was to install a brand new FRP. Even though I determined my FRP was working I figured I go ahead and get a new one anyway. The second thing I did was bypass the fuel pump resistor with a jumper wire to drive the pump at full...

    97 FZJ80 Stumbling off idle

    Unfortunately no. It has gotten a little better on its own and If I let it warm all the way up it is drivable. Its not my daily driver so it tends to get forgotten sometimes. I still think the problem is the MAF. Another member was supposed to send me a MAF to try. Also, unfortunately, that...

    97 FZJ80 Stumbling off idle

    Hi Guys, no I still have not figured out what my problem is. Squash Just like you, my rig needs to be fully warmed up before it will drive. I have cleaned the Maf a couple of times and it seemed to help but its certainly far from right. I really don't think its the ECU temp sensor because I...

    97 FZJ80 Stumbling off idle

    Nice Buck Whaler! That is exactly what I did. IT did not seem to make a difference this time. Then I fooled with it some more, Added my jumper back in to drive the fuel pump at full voltage and let it warm up real good. It still has a hesitation but it ran ok. Good enough to get me home...

    97 FZJ80 Stumbling off idle

    Well I hate to say it guys but my joy is short lived. Friday got in the car and headed up to my hunting camp upstate. The truck made the 180 mile drive just fine. We hunted sat and sun with 2 bucks to show for it. One for my son and one for my good friend Lee. The Sunday buck was a good...

    97 FZJ80 Stumbling off idle

    I just wanted to give you guys some good news I got it fixed. When I wrote the above post the mass airflow sensor was sitting on my workbench disassembled as the manual states to test it disassembled. Even after it tested well including the test to check the voltage while blowing air through it...

    :bang::bang::bang::bang: Arg Looks like the MAF is checking out as per FSM. I almost wanted it to be bad even though they are about 900 from Toyota and back ordered until December something even if you want did to pay that much. At this point, I am still lost. I went through all the...
