Had same fault a year ago. If yrs is same as mine was it turned out to be bad alternator. Internally loose connection on fat wire.
Hello,
I have strange case. Opel Combo with Isuzu engine 1.7DT, year 2004. Engine ECM does not send timing signal for injection pump ECU. I've checked errors, all clear. Fuel doesn't come to injectors, as timing valve is still closed (checked with oscilloscope).
Wiring checked, ECM reads CKP & injection pump position sensors correctly. No immo errors. Replaced ECM, and still the same.
Does anybody know what could be the problem?

V Series TMS470 / EEPROM data - encryption / decryption, totally pwned.

OK, I'll try to check it tomorrow
Confirm module on back side,near starter,some times give problems
Hello my friend,
1.Check the fuses
2.Check the injection control module located in the back of the engine block,let someone crank and you hit the module with something light while someone is cranking (sounds creepy but it actually works)
3.Bring fuel with a hand pump

Solder joints and transistors already checked. Edu connected to square generator gives signal to valve. I've inspected it once again, Instrument cluster security code was not programmed. Now cleared, still no injection signal... I also applied plack to suction collector, engine works. Any other ideas? I'm getting little bit nervous with this one
VAUX-COM gives me info: Desired Idle RPM: 0;
What does it means? Pump EEPROM erased? Something else?

Check contiunity between pump and edu ecu had corroded wires before
does red/blue have power on it?

There is 1v and then 4V on ECU PIN 33. I checked ~~~~inuity before, also cut off cables and put new ones between ECU and EDU... I'm still wondering why ECU doesn't want to have idle speed. As I wrote before:
Desired Idle RPM: 0;
Put scope on crank sensor & crank the shit out of it.
see if you can find dk thanks button
