No injector pulse they have power no no pulse

Ford Mechanic: roy, import/domestic specialest replied 2 years ago

ok. inspect the wiring harness for any damage back to the pcm.

the pcm gets it signal to fire the injectors from the crank sensor. when it sees that signal, it will start to pulse the injectors.

ok I look at the wires and I don't see no damages and I tried the pcm with another van and is working ok where else can I check

Ford Mechanic: roy, import/domestic specialest replied 2 years ago

you cannot use another pcm from another truck. it needs to be programmed to your truck to even work.

how did you determine it worked???

Have you cleared out the fault codes then tried to start the vehicle to see what codes come back again?

Ask Your Own Ford Question
Customer reply replied 2 years ago
Same codes the po230 and po232
Ford Mechanic: Pete, Auto Service Technician replied 2 years ago

O.k.,the codes here are for the fuel pump relay circuit.Do you have a test light or multi meter and can you locate the fuel pump relay and remove it (keeping in mind which way it was installed) so we can test signals at it?

Let me know,thanks Pete.

Ask Your Own Ford Question
Customer reply replied 2 years ago

yes

Ford Mechanic: Pete, Auto Service Technician replied 2 years ago

I apologize for the delay.

With the fuel pump relay removed test these signals at the relay and let me know what signals you have.

One terminal should have power at all times key on or off (at or near 12 volts)

One terminal should have power with the key on or engine cranking

One terminal should have a ground with the key on the first two seconds only or when cranking over the engine only.

Let me know what signals you have here.

Thanks Pete

Because of your expertise, you armed me with enough ammunition to win the battle with the dealer. They are installing a fuel filter and fuel pump at no charge to me.
