The injecter loop is closed on the obd-ll emc.
most injector systems have constant power to all injectors and are activated by the fuel computer sending a ground signal topower up the correct injector at the correct time g
Fuel pump NG
no gas no power
There are numerous issues that can cause a lack of power during acceleration. Common causes include a clogged fuel filter, a clogged air filter, and dirty fuel injectors.
In a 1988 Ford Ranger, fuel injectors may not receive power due to several potential issues. Common causes include a faulty fuel injector relay, a blown fuse, or problems in the wiring harness, such as damaged wires or poor connections. Additionally, issues with the Engine Control Unit (ECU) or a malfunctioning ignition switch can prevent the injectors from receiving the necessary electrical signal. Diagnosing the specific issue typically involves checking the electrical supply and continuity to the injectors.
Electrical impulses from the engine control module (ECM)
Sounds like the ECM is toasted.
low or no fuel pressure clogged injector no pulse signal coming from fuel compter
use a noid light set to determine if pulse is going to the fuel injectors.
Are you getting power to the system?
There could be several reasons for a lack of fuel at fuel injectors. Common causes include a clogged fuel filter, a malfunctioning fuel pump, or issues with the fuel lines, such as leaks or blockages. Additionally, problems with the engine control unit (ECU) or faulty fuel injectors themselves can prevent fuel from reaching the injectors. Diagnosing the specific issue usually requires a systematic check of the entire fuel delivery system.
Replace you ignition module, It controls both spark and power to the injectors. You can have spark but the module may be bad and not giving power to the injectors and the vehicle will not run.
Not enough fuel to them. Most l;likely a fuel pressure regulator problem
