Car won't start

[Ivan141]

Fii, the ECU doesnt put out 12V at all... I think the injectors have a coil in them, which causes an inductive field that opens a switch when current flows through it. A coil is basically a fancy short circuit, so it's logical that you would read 12V at both ends of it when one side is not connected (or floating as it is called).

I dont know if there's a simple way of checking if the ECU is actually pulling the signal low when your trying to start, but that would offcourse be the best way to see if they are firing. Have you tried to put the ECU in diagnosis mode yet? Might give you some helpful information.

I think it's most likely just a minor electrical problem, hope you fnd it soon. Also make sure you check that all the grounding points of the wiring loom are correctly connected, it can cause weird problems sometimes..
