cutting out at 3800 rpms
 

OK i have had this problem sience i bought this car and its getting annoying we had the car checked my a toyota dealership they coludnt fiure a way to check fuel pressure is there a way also i am thinking about putting a nerw fuel pump and pulling the injectors well just needed to ask please respond

Any Toyota Dealership should be able to check fuel pressure. If they can't they need to close up shop....HeHehe.

Heres a copy of the TSRM, look under EFI and it will tell you step by step instructions.

MK3 TSRM On-Line

ok got that
 

i already got the manual i cant find the banjo fitting any one have this problem before

First off we need details on the car.

Turbo, non turbo?
Is it 3800 every time or around there.
Is it under the same throttle condition i.e mashing it or only slowly revving. Does it doo the same in neutral?

Have you done a basic diagnostic? How to is in my signature :)

ok now what
 

no codes on diagnostics 88 n/a well no clue in neutral it dose it around 3800 when i ease into it or mash it i want the car so when i hit the gas hard it goes

Does it stutter like it's missing or is it a hard cut? Does it lose power as it's getting to 3800 or is it strong till it gets there?

the car runs strong untill about 3800 then car cuts out hard like its starving for fuel

Sounds an awful lot like fueld cut...
 

Ifr your stock turbo hits 12psi - the fuel is cut-off until it drops to ten.
This MAY be your issue. The other possibility is lean fuel mix (injectors / fuel pressure)The jerking is pretty severe when fuel cut occurs... Its like keeping the gas floored and turning you ignition key on and off.

If this is actually your issue, then your wastegate has probably been shimmed to let the turbo spool higher than 8 pounds. You are a full 25% over the assigned boost range, so that's why it is a pretty earth-shaking cutout. SOLUTION: FCD Fuel Cut Defencer. Watch out if you get one: the wiring diagram that comes with it sucks - look on this and supramania for correct diagrams. This is not a simple upgrade - you need to pull apart the passenger side dash and extract your ECU. It's dark cramped, and a royal pain, but the results are pretty fantastic. I have stock CT-26 turbo and it can and does hold boosts above 20psi now without issues. I have peaked boost at 28.5 psi using an AEM tru-boost guage / solenoid. The car is a lot of fun! I will say that!!

You did say it's non turbo? No codes? I would test your distibutor. Test the cam sensor and igniter, which should be part of the ditributor assembly. Or just check out the condition of the cap and rotor and wires. If not, check the mass air flow sensor and the throttle position sensor. Test them. Let me know what you come up with.

What is the fuel pressure. Test it at the cold start injector fitting.

Sounds Like your fuel filter is dirty. Change it today.

Pessure is pressure. Volume is your troubles.
