it has 4
are all 4 failing or just 1 .
nothing else is so important .
did you know there are 2 things that make an ecu kill all injector pulses.
?
1: TPS signalling wide open throttle.
2: no spark. or weak spark.
(assumes fuses not blown in fuse box)
The engine computer (pcm) controls the injector pulse. It looks at numerous sensors and switches to calculate pulse width
1990 ford ranger 2.3 no injector pulse what causes this
200 Nissan exterra v6 have spark and injector pulse no power to fuel pump
tools u can use are a noid light....or an injector pulser ''TOOL''
Injector pulse is controlled by the ECU. Injectors Have a red wire that is hot. Black wire is controled by computer ground...
Pulse width is the time in milliseconds that the injector is energized, the duty cycle is the percentage of on-time to total cycle time
The engine computer.
The ECU. (COMPUTER)
In a 1986 Toyota MR2, the fuel injector pulse is controlled by the engine's electronic control unit (ECU), which manages the timing and duration of the injector's operation based on engine conditions like RPM, temperature, and throttle position. If you're troubleshooting injector pulse issues, you can check the ECU for fault codes, inspect the wiring and connectors for damage, and use a multimeter or oscilloscope to test the injector's voltage and pulse signal. Proper fuel supply and pressure should also be verified to ensure the injectors function correctly.
Engine control module
The engince control computer. Why ?
faulty crank angle sensor in most cases
