    TD5 Got me beat

    I've trolled thru dozens of forum threads and am running out of ideas.
    I bought a Disco 2 TD5 with the dreaded overheat and plastic dowell issue. It was a non starter.
    So far,
    Head has been reconditioned & refitted ( steel dowells & 3 hole gasket)
    Timing done using locating pins
    Injectors fitted with new O rings & copper seals.
    New crank sensor fitted.
    All oils & coolant done.
    Wouldn't start after many purges.- tank half full.
    Tried a second ECU - no better.
    Today I bought a fuel pressure tester as I was convinced it was a fuel issue & it was even higher than it needs to be.

    Nanocom triggers all injectors, it says no faults but scrolling thru it does say imbalance between 3&4 cyls, also the injector codes are incorrect but this is a fine tuning issue, shouldn't cause no start. Cranking shows 207 rpm, and battery does go to 10.47 volts after about 5 secs, its a good battery, showing more cca than spec on the tester.
    Any idea's what next? What does aerostart in the intake tell me if it fires?
    If I had hair I'd be pulling it out about now..

    So you can actually hear the injectors click?

    Have you checked that the ECU isn't immobilised? I know you said you tried another one but just thought I'd ask.

    I'd check to see what it says, then try and sync and see what it says after.

    Aerostart basically tells you nothing except you have compression and the valve timing *may* be ok. Compression ignition engines will fire on aerostart.

    d battery does go to 10.47 volts after about 5 secs,
    That is too low for the injection to trigger.

    I just went to the garage & Nanocom ( its the older one) says Immobilise not activated. Another possibility done..

    Thanks, I'll charge it overnight tonight, it is a 810 cca, supposedly new & my tester shows it healthy at 845 cca, Beginning to wonder if the starter is pulling all the power.

    Just for interest sake, went out and unplugged the injector loom, plugged in the Nanocom (evolution) and cranking speed sits at about 220 rpm, battery voltage on the nanocom showed between 10.0 and 10.7 volts.

    That's obviously not actual battery voltage.

    It sounds quite lively at those readings.
