Mr2 1985 , I had check the relay and fuse already. Everything its find . But not injectors pulse. Thank you for your answer.


The injector,s get there pulse from crank or cam sensor,and if equipped the ECM.

It's till not luck fuse and relay are good. Injectors are good. The show 12v on switch close. And I don't think my car has a crank or cam sensor. Mr2 1985 . Car still doesn't come on , it crank but not gas. Gas pump its good. Does any body knows


The computer on the car controls the injection The 1985 MR2 uses the 4age engine an AFM, TPS and the PCM -computer it controls injection pulse width

Might be your fuel pump or throttle body. I had my throttle body rebuilt on my 86 MR2 because it was struggling to start, works great now. If you can't narrow it down, go to a dealer and at least get their assessment, rather than trying everything and wasting time and money.
