rb25 no spark, or fuel, please help.

[DropTopRB]

So i installed a rb25det into my 93 240sx convertable, and im having some problems getting it started, Im not getting any spark, or an injector pulse. I have checked over all of the wiring to the ecu and its all correct. Im not even getting a constant power to one side of the injectors. I did bypass the trans in nutral switch on the side of the fuse box, seen as how it was an auto transmission before. Also, its a series one engine, and the 2 pin connector that goes into the coil packs, isnt getting any power.

Any ideas would be really appreciated, Thanks!

I checked my ecu for codes, its throwing a 34, and according to what i have read thats a detonation sensor circuit code. Anyone know what a detonation sensor circuit is??? and where i could start to diagnose????Please help, im about ready to sell off this project... or just get another sr

detonation sensor sounds like knock sensor talk to me.

Anyways, do you have voltage to the ECU? If the wiring was done right it. Having spark and fuel both out sounds like ECU problems. Voltage in, voltage out.

FSM should have a diagnostic on the ECU and particular problems.

Did you check the relays by the ecu? on my 25 they were bad so i wouldn't get any spark.

there are two blue empty relay blocks near the ecu and the white connector, should there be relays there?? If so, does anyone know where i can get some, or some part numbers??? Thanks

We have some. You also can get them from Nissan . Blue relay is sames as the S14 KA harness. Also Most store like NAPA, Kragen will have them...

does anyone have a part number for these relays???? Or some good used ones?
