    Default 4age ae82 no spark or injection

    I have a ae82 16v with no spark or injection while cranking. I can't hear a fuel pump either. The main EFI relay is clicking and there is power to the coil etc (disconnecting battery with ignition on makes a spark jump with the main lead off so the coil seems to be working)

    Not really familiar with this engine, is there any main parts to start checking? The battery terminals had been chopped off before i got the car. I have an earth from block to bat and one from bat to body also. One the +'ve the main white 'body' wire is connected, as well as the starter fat cable, and a black wire with a red stripe. It would seem that the power side of things is sorted, but still no spark, and from what i can hear and see no fuel pump or injection.

    is there a way to see if the computer is fried apart from having another spare to replace it? I've just got the car and its getting dark so i'll have to have a better play around with it tomorrow.
    Thanks in advance!

    just cos sparks fly doesnt mean you have power to your coil, do you have a multi meter?

    Test for voltage at the fuel pump.

    if you have a timing light connect up and see if you getting spark as you crank, it will flash if you do.
