1uzfe Stalling

[Thomas DK]

When I turn the ign. on the checklight wont come on, but the engine will fire up anyway. Then it stalls emidiatly and now the check light is on. when I crank it again it keeps running(again with check light on), but stalls when I try to increase RPM.
Its not giving any errorcodes away, not even the OK-flashing

I'm fumbling in cirkels now.

New input and suggestions please

hey

From my experience in Honda ,there's this sensor call the MAP sensor ,maybe it's a different name for Toyota.. If your engine light is on after engine start,see whether you have loose or connectors not connected. If your engine keep stalling when increased throttle, look out for vacuum hose not connected..

Fuel pump might be running when cranking
Then stopping once key goes to ignition

Fuel pressure ok.

MAP sensor??

The engine is not in a vehicle at the moment, but wired up correct(I suppose...)

Proper ground on engine, igniters and both headers(from harness), + to the Black/Yellow Black/orange and Black/red in engine bay, and crank signal to black.

I've messured the ECU pins and getting all the right values.

Maybe i'll start knitting instead

Did you wire it up yourself? Have you used a main relay? Can you show some photos of the setup? Cheers

its probably stuck injectors
so its running on cold start injector if thats even wired up

pics right after easter. I'm out racing B-)

Its been running perfect a few times, so I'm not suspecting the injectors. And I would they be able to turn off the engine check light?

ok cool didn't realize it had been running before
can be a million things as I've been on phone with customer
of mine for 2 hours trying to get his going and not getting to far
check basics. spray fuel down intake to see if it s runs
