s13 rb20det injectors not spraying

[@irborne]

Hi guys,

i did a swap rb20det (silver top) into the s13, wiring seemed ok, except the injectors are not spraying. the motor runs if i spray some starting fluid into the intake manifold. it runs for a few seconds and stop. fuel lines are pressurized, registering at 40ish psi; the feed line and return line are connected correctly.

can someone confirm with me which wire powers the injectors?

(Mods: I'm not sure where this post should go, but I'll try here.)

thanks,

dan

What ECU are you running?

1 side of the injector should have 12V (depending on wiring, both sides might, because standard wiring keeps permanent power to injectors). You should be able to hear the injectors pulsing (click click click...) as you crank the engine.

Did you wire the relay for injector power?

One side comes from pure power, then the negative gives the pulse straight from the ECU.

Might pay to check. Get a multimeter and check signals at the injector plugs.

i did some tests and no power is going to the injectors. i might be missing a wire that feed power to the injectors.

Might be a dead relay or something.
