It's a fused circuit, so check the fuse, probably under hood, labeled injector. A shorted injector can shut down the injector drive circuit, so pull off all injector connectors, make sure fuse is good, then check for power to the injectors. Injector circuit should nave hot wire anytime key is on. Has constant voltage to injectors. When the computer internally grounds the injector ground wire, the injector will pulse.

WHAT CAUSES THE FUEL INJECTORS NOT TO PULSATE? OR, WHAT CAUSES THEM TO PULSATE IN A 1998 FORD MUSTANG 3.8


the pcm monitors fuel requirements through sensors so it knows how much fuel is needed to keep the motor running under different demands depending on what or how the driver is driving the car.the pcm grounds the injector circuit while supplying power to the injector all the time the key is on.when the pcm grounds the injector,it opens it allowing fuel to enter cylinder to be burnt for the on time(open injector) that is required for the demand on the motor.

What makes injectors pulsate on a 1994 corsica with a 3.1


When you turn on the ignition, power is provided to one side of the injectors. When you start the car and it is running, the computer grounds the other side of the injectors. The length of time that the computer grounds the injector is known as the pulse width. This "time" determines how much fuel is released from the injector for any particular engine cycle.

2000 mitsubishi diamante has spark has fuel up to the injectors and power but wont start.


At injector's, need to check if you have ground pulsation, to check, connect test light on pos (+) battery terminal, now your set to check ground, at injector harness, probe wire's, while some one cranks engine, look for pulsation, if you don't have pulsation, it will need a computer, injector pulsation is control by the computer, if no pulsation, then no fuel can get into cylinder.

No fire no injector pulse no power to fuel pump


The computer sends the signal for the injectors to pulsate so have the computer checked first

It isn't getting fuel to the motor. Fuel pump is working, but does it have a reset button or some sort?


You still need to do a fuel pump pressure test.I seen where you can hear the fuel pump, but no pressure, if good pressure you'll need to check for injector pulsation, unplug one of the injector harness connector (will have two wires) with a test light with key on check for voltage if test light lights up, then reverse test light at battery, now you'll check for pulsation check other wire that will be ground, have some one crank engine test light should flash, if no flash will need to have computer diag. injector get ground from computer (possible bad computer.Good luck.
