What are the grounds for the fuel injector driver?
Circuits E01 and E02 serve as grounds for the fuel injector driver circuits. To provide a redundant ground for the ECU, these two grounds are tied to the E1 circuit through a diode. In the event that the E1 wiring to chassis is open circuit, E1 circuit current could flow through the diode to ground.
What happens when the ECM on a Honda Accord goes bad?
As mentioned above, the ECM controls the engine timing, and air/fuel ratio. So, when it goes bad, it can knock your Accord’s air fuel ratio off. This could lead to poor fuel economy, the previously mentioned rough running engine, backfiring, a flashing check engine light, and an engine that has no giddy-up and go. 4. Failure to Start
Why are the injectors in my car not working?
It can also be caused by excessive cranking without engine starting so we should not worry about this as it is the injectors that are not working. Lets try this. With test light connected to injector RED wire. Turn ignition on. Test light should come on. Crank engine. Test light shoudl remain on.
Is there a problem with my Honda Accord?
No sputter no nothing. It cranks and cranks but would not and will not start. Had the car towed home and the next day I replaced the fuel pump because I couldn’t hear it making that whirling noise, so I thought for sure that was the problem. Well, it wasn’t I guess. It still cranks like it wants to start, but will not.
How does the PCM control the fuel injectors?
Based on the cranks sensor signal, the PCM grounds the injector to allow the injector to inject fuel into the cylinder. It makes and breaks the ground many times per second to allow the proper amount of fuel into the cylinder. helpful? That sounds fine, but the wiring diagram in the shop manual does not match that at all.

What causes no power to fuel injector pulse?
Ans: The engine control unit is the electronic brain that used to control the fuel injector pulse by gathering data from various sensors along the fuel line Question: What causes no power to fuel injectors?
Are there injectors fired in pairs in a 1994 corolla?
@Cougar my 1994 Tercel injectors are fired in pairs. I believe my 1995 Corolla was the same way. I believe that all current cars have sequential injection, though. But you guys are right about the injectors. The PCM provides the ground. UPDATE: Hi, There are no breaks in the injector connector driver (ground) wire to the PCM.
