DRiiFTiE Posted January 22, 2017 Share Posted January 22, 2017 Any ideas? Cannot see any split vac lines. Must be a Fuel / air problem or timing jumped? Quote Link to post Share on other sites
Nafeez2125 Posted January 23, 2017 Share Posted January 23, 2017 Do a diagnostic see if the code for TPS comes on, if not then check your throttle position sensor. might need to be calibrated Quote Link to post Share on other sites
MR-2 Posted January 23, 2017 Share Posted January 23, 2017 Fuelpump problems sometimes cause that kind of thigs, don't deliver enough fuel under raising pressure. Easy to test with fuel gauge between filter and fuelrail, then test drive. Toyota services have those gauges, I have loaned few times... Quote Link to post Share on other sites

Cannot drive it tho bud.. will idle perfecf but soon as try use throttle more than 1/4 it will try to cut out Quote Link to post Share on other sites
5e colin Posted January 24, 2017 Share Posted January 24, 2017 check if map sensor is connected /working !! Quote Link to post Share on other sites
DRiiFTiE Posted January 24, 2017 Author Share Posted January 24, 2017 check if map sensor is connected /working !! Definitely connected, whether its working or not is a different question, i tried one out of my other glanza that is fully running an seems to be the same Quote Link to post Share on other sites
Nafeez2125 Posted January 25, 2017 Share Posted January 25, 2017 Have you checked the TPS? Quote Link to post Share on other sites
DRiiFTiE Posted January 25, 2017 Author Share Posted January 25, 2017 Have you checked the TPS?Yeah swapped to a working one but no luck. It also sounds like sucking in air from somewhere when you rev it.. but cannot see no leaks or splits. Has a little whistle to it when rev.. replaced absolutely everything today including fuel pump, tps, map sensor, all the ignition, no luck. Guessing the timing has jumped and altered the fueling/air check if map sensor is connected /working !!Yeah swapped to a working one but no luck.

Nafeez2125 Posted January 26, 2017 Share Posted January 26, 2017 i recon there is a vacuum leak somewhere. try spraying some carb cleaner on the pipes and the around the intake gasket while its on and see any changed on the engine sound. Quote Link to post Share on other sites

I've ordered a new inlet gasket as that isnt in the best condition.. but pretty sure that wouldnt make it not wanna rev/wanna cut out.. there is a sleight whistle on throttle so guessing thats a leak somewhere Quote Link to post Share on other sites
gorganl2000 Posted January 26, 2017 Share Posted January 26, 2017 did u do the diagnostic? Quote Link to post Share on other sites
DRiiFTiE Posted January 26, 2017 Author Share Posted January 26, 2017 did u do the diagnostic? Not as of yet no.. sprayed cleaner everywhere and cannot find no leaks.. the second i spray cleaner around the boost pipes/turbo area it changes its tone an goes to die for a min.. then back to normal.. making me think the turbos shaft has dropped Quote Link to post Share on other sites
gorganl2000 Posted January 26, 2017 Share Posted January 26, 2017 i'd suggest you do the diagnostic and let us know if you find any codes...will only take a minute then we can go further from there, as you have already done some stuff Quote Link to post Share on other sites
Nafeez2125 Posted January 26, 2017 Share Posted January 26, 2017 yeaa, get the diagnostic done check link below. http://www.toyotagtturbo.com/forums/showwiki.php?title=EFI+self-diagnosis+system Quote Link to post Share on other sites
5T4R7ET N/A Posted January 26, 2017 Share Posted January 26, 2017 If the engine want to cut out when you spray the cleaner on the intercooler pipes, you have a leak. Check the pipes the holes and redo all the clamps tight. Then re check with the cleaner, nothing should happen when cleaner is sprayed over the intercooler joints.

Terry1.3GTT Posted January 26, 2017 Share Posted January 26, 2017 No way, i went to my car this morning after it sitting for 3 days and boom, straight into limp mode....wouldnt go over 2000 rpm, or like you say 20% throttle. Took it to the guys i know at the garage and it turns out the tps signal from the ecu isnt producing the 4/5 volts needed to say that the throttle body is fully open. They tested the signal from tps to ecu was fine on open throttle but the signal then from ecu wasnt coming out. They put artificial 4/5volt signal to the wite and it revved up straight away!! Turned of the volts, and wouldnt go over 2000rpm. Another ecu is on the way and hopefulky that will solve the problem, then i will get the old ecu checked out. Old ecu being a JAM pnp one.

Terry1.3GTT Posted January 26, 2017 Share Posted January 26, 2017 Il let you know monday weather mine works out ok. But its deffo the signal going to the TPS from ecu ( think its the pcw or something like that wire on the ecu pinout as there are 3 pins for tps) but as soon as a voltage was manualy put to the tps, via the wire the engine picked up again and would rev up like normal. Have you changed your tps? Quote Link to post Share on other sites

Have you changed your tps?Tps changed an reset, compression test done and all good.. timing is all good. brand new plugs are now black so fuel/air must be wrong!

Terry1.3GTT Posted January 28, 2017 Share Posted January 28, 2017 If air fuel was wrong i think it would cut out. My symptoms were, when i pressed throttle all the way down, it just revved to 2000rpm then cut , then back to 2000 then cut almost like you are just stabbing the throttle on and off.New ecu arrived this morning, fitted buy the garrage and all is back to normal. Pick it up on monday. Quote Link to post Share on other sites
