Tech reads -0.1 without crancking the engine. Can't read while cranking because tech screen closes when cranking the engine.

Need to power it off another battery then we need that reading

Soo.. while he didn't yet test with the tech hooked up to another power source, he did something else.
Without cranking the engine, he put pressure in the orps directly and tech read the same pressure as before, 0.1. Guess it's the orps then?

How much pressure did he use?

Requin · Posted: Fri Apr 05, 2019 9:21 Post subject:

Around 5-7 bar. It was still reading 0.1.

Ok should of registered about 0.7 then, but doing the white wire would show up that fault as it should of started with it disconnected

Soo, without the orps connected, the car should start?
I'm lost.

Disconnect the white wire at the injection loom plug it’s pin C it’s stamped in the plastic on the plug, the orps still needs to be plugged in but with the wire disconnected it makes the ecu think it’s got max oil pressure so if everything is right and it’s pumping oil to the injectors it should start. It will be a bit rough but it would prove the sensor is dead, if it still doesn’t start it’s something else. When the wire is disconnected tech2 will show 27.9 mpa

So... with the orps plug out, the tech reads about 27 bar. But engine still won't start. Will try cutting the wires on the orps plug but they are all red, no white, and see what it does.

With the wire cut does the injectors read enabled when cranking?

Requin · Posted: Mon Apr 08, 2019 12:06 Post subject:

We are unsure how to power tech2 from another source.
Could you maybe tell me what you are thinking is wrong, in both cases?
Injectors not enabled and enabled?
Or where to look for the problem?

Car acts like there is no fuel.
We managed to start it for a second using startetr spray but that was it.

Ah, worth mentioning that the injectors spit out oil when crancking so I guess they are enabled?
Just noticed
