yesterday morning, driving this 85 toy to work, get out on the highway, 1st, second, 3rd, 4th, almost to 55mph, but its being hesitant, like lunging not bad though, shift to 5th, cant get over 55, fawk gotta turn around . turn around, go back the other way, lunging pretty bad about this point, i get about a mile away from the house, pull off side of the road and shut it down, ok get it home, towed by neighbor who happend to pass , park it, hop in tacoma go to work, talk to long time alaska residents, talked to a knowledgeable mechanic, they said it sounds like water in the tank, i guess ice crystals freeze up water pumps and fuel filters up here, anyways i let it sit the day it broke down, today i threw into 2 bottles of iso heat, basically alcohol to get rid of the water, when i get home from work, the 85 started and i pulled it into the garage, let it idle, idling ruff as shit, go around to the gas cap unscrew it truck quits, wont start, so i pull out the haynes manual, go through all the shit it says too, i can find anything wrong, if i let the truck sit awhile, i can go out and start it, ruff idles and eventually quits on its own, what the fawk is going on, bad fuel pump, something else, any one else have these problems before, ill let it sit in the warm garage and see if that does anything for it, it is a rebuilt motor around 5 thousand miles on it, any help would be appreciated!

Check your throttle position sensor. I had similar results after a rebuild afew years ago. Problem was, while motor was gettin' rebuilt, I decided to clean all the crap out of the intake chamber and throttle body, but forgot to remove the tps. tps's don.t like moisture. Hope this helps.

sounds like the pump to me. when it quits crack the cold start injector fuel line a bit. if it squirts out vey hard, u have good fuel pressure. if it just dribbles, u have low pressure. check the fuel filter also.

wouldn't be a simple as a clogged FF?

or the Cat???

 

[miniyota]

see if you can pull any codes from the computer. anytime my truck starts to run like crap i check the computer. if its not in the computer i would change your fuel filter. then check your cat. then check your fuel pump.

good luck let us know what it is!!!

Sounds like what was going on with my car....was a clogged fuel filter....just after I got it that was goin on....filter was so clogged I could not believe it...try that 1st...

 

[bconrey]

Fuel air spark, right? Dunno what you've tried so far but I'm with zuk on this one - FF is easy and cheap, 'sides it's probably time to change it anyway.

In my experience if your cat is plugged the damn thing gets red hot; run it at night and poke your head under and take a look.

Good luck....

ok, i have a new fuel filter on it, replaced it about 3 thousand miles ago, anyways its been in the garage the last 2 days, it does the same thing, fires up ok, then rpms drop and just dies, im thinking fuel pump, damn they are exspensive though, hmm fuel sensor ill check that out also, any other suggestions,, i guess i need to find the fuel line and check that pressure, is there anyway to run a inline fuel pump, instead of the tank pump,,,

the cold start injector has the big white screw, am i correct, i installed a new ff on it awhile back, ill check that cold start tonight, thanks

 

[kneebuckler345]

The big white screw is not the cold start injector. Check your manual then jump the service connector And "CHECK THEM CODES".

is there anyway to run a inline fuel pump, instead of the tank pump


You should be able to plum an inline pump...must make sure it is at least the same psi as the stocker...I had a trooper I did this to as a backup..I had to remove the stock system and plumb an extra line next to the factory line with a filter on the end...then capped the end, until it is needed...I had extra gas lines that I attached to it and plugged em...so if it failed then I could just hook up the rubber lines..this is an old Izuzu trick and may not work here...but it should in basic thinking..I used a ford elect inline from a ranger or bronco II if I recall...40 psi.

SO, it can be done, im gonna search on fuel pump related threads, and see what comes up, no since in beating a dead horse. but i cant justify paying 185 dollars for a fuel pump, thats rediculous, hell i gotta go find the cold start injector now, i always thought it was the one with the white screw with the spring wrapped around it.

so what is the big white screw, i do have a haynes manual and the factory toyota manual, but i guess ive been playing with the wrong thing for the last few weeks, anyways i need to search on how to check them codes

 

[Wickedtoyz]

where is the tech on code checking???? i just read through tons of stuff, or should i say how to check codes,??

Dam, it has been a long time since I had to pull codes from my rig. I am probobly wrong on which terminals to jump, but in your engin compartment, right next to the main fuse box (pass side) there is a little black box with a top on it (approx 1.5" square). You need to jump the #3 and #5 terminals counting from left to right with a peice or wire of a paperclip. Turm your ignition in the on position which makes the engin check light flash, it will flash in series **** ** = 42, * ****** = 16 ect which are the codes to crodd reference. Just know that it may flash more then one code.

Maybee someone here could chime in on which terminals to jump.

there is a code index in the Haynes manaul

i do have a haynes manual and the factory toyota manual,

Ok, you have the factory manual, but have you done what it says?

The codes should be in it, but they have them online at off-road.com also.

Actually, the test connector on '86 and older 22RE's are located over on the driver's side fender. '87's and up are next to the engine fuse box. As for the codes,

I guess VT Toy beat me to it.
