evo 8 electrical problem

Symptoms -- Injector 3 just sprays constantly.

P0203, P0340, and P0335 -- Injector3, cam and crank sensors. All pretty much came on at the same time.

Checked the WHOLE god damn harness. Found no broken wires.

Injectors sent out and checked by ID -- found nothing wrong but cleaned them anyways.

Swapped ecu's out - still no change.

Swapped out cam sensor -- still no change.

Pulled off timing belt -- crank sensor "looks" fine.


....wtf....


I ohm'd the crank sensor of 3 other running evos and came back with 15.1-15.8ohms. Then i ohm'd mine -- I came up with 19.9. My cam sensor ohm'd out the same as the other evos.

Does anyone know the sensor range for the crank sensor? Any other ideas here?

According to FSM
Crank Position Sensor
Engine: cranking 0.4 − 4.0 V
Engine: idling 1.5 − 2.5 V

Don't see a resistance noted

Thats the problem -- Idling is nearly impossible. Plus all that fuel will ruin rings etc.

For S&G's have you tried another crank sensor. I know it's a PITA just to "TRY" but certainly your narrowing things down at this point.

Most times I've seen it'll throw the CEL for both crank and cam angle sensors if there is an issue

Ok - so im convinced that in the 6 weeks that ID had my injectors.. they didnt actually do **** with them.

Because I for ****s n giggles put a STOCK set in... with the resistor box plugged in.


Car runs fine.


****in ID junk and tech.... FIC's are on their way. If they go in and work fine.. im going to send the ID's back and demand a refund.
