    Backfiring and hesitation under load

    If you hold the throttle open a little, will it start and run?

    92 sc400 code 31

    The repair manual can be prone to dramatics sometimes. If the ECU cannot determine the cause of the fault, it blames itself. I have seen plenty of ECU's replaced unnecessarily when techs only follow the DTC guide. Start by removing the air flow meter connector and inspecting the terminals. Look...

    Backfiring and hesitation under load

    It could be a bad plug... it could be anything at this stage. Don't worry about the sensors for now (especially if you've already replaced them) Focus on the wiring. Disconnect the sensors and the ECU - test the wiring between them

    Backfiring and hesitation under load

    Given the age of the car, and that you've recently disturbed all the wiring and connectors, it sounds like you have a poor connection. Code12 will appear if the NE, G1 or G2 sensors are faulty, or if there is an open or short circuit in their wiring. Given you've just replaced them, I would...

    Backfiring and hesitation under load

    Code13 with log when the crank signal drops out (even momentarily) or when the logical pulse count from NE, G1/G2 is out. When you clear the code, does it reappear immediately? What has happened with the vehicle in the immediate days before this fault occurred? How long ago did you have the...

    No fuel no spark, engine cranks

    Sounds like you've almost got it sorted out - good stuff

    No fuel no spark, engine cranks

    Does the tailpipe smell fuelly? Codes 25/26 both use 2-trip detection logic, meaning that the ECU needs to see the fault occur twice over two consecutive "trips" (turning the ignition key on then off is considered 1 trip) In theory, you should be able to disconnect the battery (to clear the...

    No fuel no spark, engine cranks

    Sorry I don't know what codes 11 and 16 are on the 1995 model. When it starts up without brake cleaner, do you need to open the throttle at all... or does it help?

    No fuel no spark, engine cranks

    Just make sure the igniter housings are earthed properly first! It doesn't show in the wiring diagram, but the internal igniter circuit finds earth through the aluminium case.

    No fuel no spark, engine cranks

    All good - CEL should be solid with the ignition switched on and engine not running Can you confirm you are following the diagnostic test processes as follows... Diagnosis Inspection (Test Mode) Battery must be +11V or more, throttle valve closed, trans in neutral, AC switched off Turn...

    No fuel no spark, engine cranks

    Did the check engine light go out? Or, is it flashing and, if so, what code(s) is it giving you? How are you confirming it has no spark?

    No fuel no spark, engine cranks

    Fix one problem, only to find another. Normally a fast flashing CEL means the ECU is in test mode... do you still have the jumper pins connected to the diagnostic connector? Does the engine start now? Someone else may be able to chime in here, but I've never checked cam timing from the TDC...

    No fuel no spark, engine cranks

    DTC 13 is caused by the crank sensor cutting out while the engine is running, or logical errors in the pulse count the ECU is receiving from crank and cam sensors. If you have replaced the sensors, it likely to be a poor connection (open or short circuit) in the wiring between sensors and ECU...
