    Nick and I spend some more time this evening.

    We did verify all the major ground connections were good.

    A computer with the proper ports was used but it would still not see the ECU. We thought we might have found the problem when the case was grounded and the software said it was now connected. It wasn't, as it would still not connect and show the map. The case is supposed to be mounted on foam for vibration isolation but instruction don't say it needs to be grounded.

    Nick's contacting DTA for their input.

    I suspect it's toast.

    The ECU error codes will be of a tremendous help in ruling out sensor errors.

    I'm looking forward to the next chapter of this mystery.

    Doug was amazing and has really gotten me closer to getting this figured out. I'm putting together an image in VMWare to try and read from the ECU. Hopefully that will reveal all and then I can start tracking down parts and getting them installed. Doug also found and fixed a few other problems that I wasn't even aware of... I seriously cannot thank him enough for coming down yesterday and helping with this. I'm actually starting to believe I'll have this car on the road in a few weeks now!

    There was some problem with the editor. When I saved some changes it did not show up on my computer. So I did it again and again. It was clearly sending it to the website but it didn't show up at my end. Honest, I don't repeat myself I don't repeat myself I don't repeat myself.

    Hopefully corrected now.

    The harness could have a bad crimp but it looks well made and we can look at that after we can connect a laptop to the ECU.

    Nick is a computer wiz and may be able to get his newer laptop to work. It needs a serial port and the USB to serial adaptor he had didn't work. If not I have an older one that should work.

    or a bad crimp somewhere in the harness.

    Doug,

    It sounds like it could be a bad ground - especially with it being intermittent.

    Oh, and I almost forgot, is it getting fuel?
    Brad, great questions. Hopefully Doug will chime in soon and provide some clarity here. :D

    It wasn't the starter but no spark.

    Cause not yet determined but I suspect:

    Crank position sensor.
    DTA ECU (E48)
    Coil pack.
    Some other intermitant wiring demon.

    In trying to find the cause we removed an ignition cutoff switch that might have been faulty. A nice backfire seemed to indicate we were on the right track and my spark tester said it was getting spark. By the time all was back togther again, no spark. More testing of the wiring involved and we could not get it to produce a spark.

    The car has Webers not FI and it is getting fuel.

    The wiring harness has power and ground to the correct pins. Coil pack too.

    As we didn't have the proper hookup to the DTA we weren't able to see if it's the ECU, cranks sensor, or ???

    Hopefully when he can connect a laptop it should tell all.

    We also found that the throttle cable had slipped in the mounting and it was only getting about 5 degrees of throttle opening.

    Have you done a search here:

    http://www.blatchat.com/

    Seach in the tech section back to the beginning on 'Vauxhall Starter'

    Plenty of others with similar issues but I haven't had time to read them all for a cure.

    Did you try bypassing the battery cutoff switch.

    I seem to recall reading about them failing.

    It should be an easy thing to try.

    It should have a big cable from the battery negative terminal to the block and/ or chassis. If it goes from the battery to the block then another to chassis that should be fine or vice versa. Be sure all the connections are tight.

    Does it have a battery cutoff switch? Should be a big red handle someplace. On my car if this is switched off the solenoid will still click but the starter will not turn.
    There is a battery and an ignition kill switch, but they're definitely toggled into the right position before I am attempting starting. My car has no power at all when the battery kill is on, so I know that is functioning. The ignition kill I've toggled both ways in the hope I'd just gone senile and forgot which way it was to be set for starting... No good either way. I have full lights, both on the dash and lamps. I will check wiring, though, as it is possible something is loose somewhere.

    I'll let him volunteer to come if he can - he already did by the time I posted.

    I am uncertain how you define turn over, do you mean the starter won't turn the engine over at all or it won't fire and start while being cranked by the starter?

    Generally a car needs three three things to start.

    Fuel
    Spark
    Compression.


    All at the right time of course. As it was running when you shut it off I'll assume you haven't changed the timing.

    Is the car fuel injected?

    Are you getting fuel pressure?

    What kind of engine managment system do you have?

    Call me for more ideas. Eight Zero Five 402-one two two five.

    Thanks Doug, I definitely will hit you up for some ideas over the weekend. I really appreciate the help!

    Oh well, my suggestions:

    - Can you still turn the engine by pushing in 5th? Just to make sure it is not seized up.

    - Does the starter at least click or even try to turn the engine?

    - Would it so so without compression, i.e. plugs removed and WOT?

    That may give a hint what to check next.

    Thanks for the quick response... I'm kind of a newb, so expect me to say, "huh?" and... "I think so..." a lot.

    - A friend and I tried to push start it last week before I changed the spark plugs. It almost started a couple times, but we couldn't get it running.

    - The starter is clicking and definitely trying to start the engine

    - I know my friend unplugged one of the plugs wires and asked me to start it, but I honestly am not sure what that told him... He seemed to think it was fine, though.

    As you can tell, I am trying to learn, but I'm a bit under-par when it comes to knowledge on this stuff. The car is definitely trying to start, though. I get a strong chug from the starter, the engine is straining to start, but doesn't.
