Emergency Need Help Concerning My Ecuuuuuu

[abostef6789]

i did an engine swap for my toyota celica gt 1987 3sge engine
i only swaped the engine and kept the old electronic parts with my old ecu
after i showed my car to several mechanics non of them could solve my problem the engine is not functioning well the max rpm i can reach is 3000 and the engine is to weak as if it needs more fuel
the first two injectors have weak voltage on them is it the ecu or the main cable coming from the ecu the fuel pump is good the distributer and the coil are good the pressure of the engine is excellent 200 thanx for ur help

Did you have 3S-FE stock or 3S-GE stock?

3S-GE i replaced the distributer ECU spark plugs and wires the wiring is all good
but still there is a chip in the front of the engine behind the intake manifold does it make like dat ??

oh, so over in lebanon, do the st/gt come with the 3sfe motor as well? well if you have the 3sge engine now you have get the wire harness and everything that goes with it. like the engine, harness, and ecu. if you are running with your stock fe ecu then thats a problem. make sure you run the ge with right ecu. the fe ecu with hold power back
