Starts then stops!

[das2000m]

I went to take my Griff 500 out of the garage and the car started as normal...ran for a few seconds then stopped again, it then restarts no problem and then cuts out again. The fuel pump is priming ok. I’ve been having a lot of issues of late with the car misfiring and even cutting out whilst driving but each time it has came ok again. Ive connected the RG but it shows no fault codes (I assume it doesn’t run long enough to register a fault ?)
To date I have replaced the fuel pump and filter, air filter, ignition amplifier and coil.
Has anyone any suggestions ?

I’ve tried several times with the same result......start run for 2-3 seconds then stop then start no problem. I disconnected the maf sensor but no difference.
I then disconnected the battery to reset the ECU, on starting the car it only ran for maybe 1 second this time but would not start again, I put an inline spark tester and found no spark! I’ve now discovered that the Rovergauge will not connect with the ECU and there is no live feed from the ignition switch to the Fuel pump relay.

Try replacing the ecu and fuel injection relays, I’ve had an issue in the past where it would start then just stop, although in my case it wouldn’t restart.

I have already replaced both relays the last time I had this issue.
Im not sure if it was the disconnecting of the battery or the moving of the loom that changed it from starting and stopping to not starting at all.
