How does a isuzu 250 freeighter get power on the dieselpump and injectors and trough witch fuse does it work

_-__-___-_ Feb 26, 2017

Hi bertie pieterse, I want to help you with your question, but I need more information from you.
you meant GOT POWER RIGHT?(NOT GET)
AND INJECTORS, AH 12V POWER TO INJECTORS(GOT)
GOT IS PAST TENSE.
BUT IT TAKES A FIRING PULSE TO FIRE THEM.
LEARN HOW TO TEST ALL FUSES FIRST?
OR LEARN TO POST SYMPTOMS FIRST.?
ARE WE TO GUESS IT'S A CRANK BUT NO START ENGINE?
Fuse are tested with a voltmeter
key on 99.9% have 12vdc on both sides of fuse. if not fuse blown. some get hairline cracks, so meters never lie.

Does it run? no symptoms stated just a hunt.
no year car(heavy truck)???
no country
why?
Freighter,
NPR or what? lots of trucks under Freighter,banner.
the 3L diesel
4JJ1-TC
direct injection type? correct? (and PCM to run it)
scan it after checking fuses?

we'd not spend all day looking free books
we see all fuse if they look bad,THEY ARE
if look good, test them , they can bad.
a voltmeter check is super fast.(key on)
if pump has power,why look for fuse.
filters clean
fuel lines primed.
if lift pump is it working?
scan the pcm for errors.
glow plugs ok.

I have isuzu elf 250 4BE1 engine but won't go beyond 80km per hour. Injector is serviced

If your Isuzu Elf 250 equipped with a 4BE1 engine struggles to exceed 80 km per hour following injector and nozzle servicing, consider inspecting the fuel system, air intake, and exhaust for potential issues. Also, scrutinize the transmission and clutch for factors restricting speed. Should the issue persist, seeking the expertise of a mechanic for a comprehensive diagnosis is recommended.

2000 Isuzu KB250 diesel with 4JA1. Hello helpers, I put 2.2 diesel pump injector on my kb 250 4ja1 so it is starting but cutting off while idling?

Question edited for clarity and add maker.
Question moved to maker category.

So the pump wasn't new? Perhaps it was broken?

Air locks in the system?

Problem for the injector can't inject

Pull off the injector connector and see if you have power on one of the two wires going to the injector, with key on. One of the wires should be hot with key on. The other wire is the injector ground. If no power on either wire, check the injector fuse. If fuse is good and is passing power with key on, check for broken wire between fuse and injector.
If you have power on the injector drive wire at the connector, post back, and I can walk you through checking the injector ground. You would need a simple test light.

I have a 92 chevy caprice that seems to have no power to the injectors what should i do?

You need to keep testing the wire back till you find power and fix what ever is stoping the power from getting to the injector.
The power for the fuel injectors comes from fuse 11. Fuse 11 gets it power from the ignition switch. The wire at the ignition switch is pink. The power going to the ignition is a red wire witch come from a fusable link.

There is no power getting to the injectors in my 91 isuzu rodeo V6 throttle body injection. i have replaced the ECM,fuses,relays even got new injectors still cannot get my injectors to turn on

Hi there, Joel here 20 year master mechanic. For the faulting to the injector pulse and power, the control mod in the distributor controls fuel and spark. You're going to have to replace the control mod. I believe AutoZone carries these at 26.99 p/n DR126. Hope this helps.
