    Angry Opel astra H 1.7d 2008 start problem

    Hi folks,i had in my garage astra that is the devil of devils :/ ... So,car wont start.There isn't proper pressure on injectors. Here is list of things that i inspected:

    1.Fuel pump,injectors,ECU,Rail sensor,crankshaft sensor are replaced,and wiring between components and ecu is inspected and it is correct.
    2.Car start on easy spray,but cannot drive it because it looses power.
    3.Starter and battery is okay.
    4.There isn't any DTCs except 2 glow plugs not working.

    Went to some guy fixing fuel pumps,he managed to get it working for 3 days,but again car died in driving. He says that he didnt do nothing except disconnection and connecting those connectors near pump.

    So this is one really tough opel,hope someone knows solution,i will be thankfull

    Cheers

    What are you reading it with?
    You need to record some live data and study that.

    Start by changing leak off pipes. What is rail pressure in live data? Do these have in tank pump? if so what pressure?

    hi guys, happy new year! so i have opcom and bosch kts540, live readings are good except that fuel pressure reading which is low, about 5-6mpa... so start authorizations engine speed etc. are good.

    autoden:leak off pipes are good, i measured injector leakings and its perfect. car has only front fuse box module,maybe problem is in there?

    Leak of pipes need vacume to test as you don't see any leak, same to filter head. What rpm do you see on cranking?

    no in tank pump on these, just the 1.3 and 1.9s..have you cleaned the fuel solenoid valve?

    no point throwing parts at it, you can create a problem with parts throwing and end up chasing your tail...it will never end.

    3staar thx for your reply.

    so i managed to pinpoint the problem, write down the list of causes and i think i figure it out it could be wiring. tomorrow i will test it and put here the possible solution
