Injector Impedance Questions ATTN: Ivan/Peter(parrot)/Banpei

[Ivan141]

Your question about the injector impedance has been answered a few times already, you dont need a resistor pack with the euro MAP ecu, it is designed to work with low impedance.

Your problem sounds familiar though. Check the circuit opening relay. The problem you are experiencing is a classic among hachi-owners. The fuel pump gets 12v directly from the ignitionswitch while cranking, once the engine fires the circuit opening relay is supposed to close to keep the fuel pump powered. Once this fails it will die directly after firing.

You can find the relay beneath the right-hand side kickpanel (on lhd cars anyway). Try running a direct wire from the battery to the fuel pump if you want to be sure this is the problem.

Happy troubleshooting!
