HELP!!! hard time starting

[fax0815]

Was the MR2 running sweet before you pulled it out?

Check the engine loom, there are a bunch of brown earth wires somewhere in the area next to the injectors (at least its there on 4AGE) Make sure the´re conected and he crimping is fine.

Unplug the cold start injector and check if the plugs still get wet after a while of cranking. (This thing throwns a lot of fuel in there, which could be mistaking for fuel from the injectors)

If they stay dry, check continuity on the injector plug loom, one should have earth, and the other obviously shouldn´t.
Between + and - on the injector should read unstable 5 or 12V with the engine cranking(???) i´d usually do this with a oscilloscope.Not 100% about that, check the engine manual for further advice.
If your anal about it search for injector pinout on the ecu and check continuity between ecu and + on injector plug.

Do it with all 4 plugs

Quickly measure resistance of the injector as well, the should all read the same, exact numbers are in the manual aswell.

I´d just temporary swap for stock 4age injectors (the came of a recently running engine??), to ensure that your agze injectors not the reason.
Set the pressure to 3bar and play a little upwarts from there with stock 4age injectors.


If it starts than your agze injectors are faulty.

Also try 4AGE injectors with stock fpr.

That´s what I whould do next.
And keep thinking about anything suspicious during the engine swap...

Good luck!
