Cant get my efi turbo in my s2 to start unless I unplug the tps sensor!

Its got the correct volts going to it. Tried another tps..icv...and injector loom but still the same issue.

Anyone know whats going on?

 

Also tried another ecu

 

Ground issue maybe. I would check ground voltages. Maybe some ground pin gets +5v due to incorrect wiring

 

Cheers, will check. Only has 2 grounds. 1 for the ecu and 1 for the edis. Will check anyway

 

On the plugs. Gotcha

 

So you solved it?

 

If you've tried good known working parts then it points to a loom/wiring issue.
If you know anyone with an OFAM ECU you could plug that in and at least be able to see what's going on, what sensors are working and test all outputs, etc.
