Today I checked the wires from injectors to ecu and to the battery. Is this ok?ĩ / ignition position, which is actived only when startingġ6 / fuse-> ignition key position, which is actived when key is in ON-position and START-positionĢ0 / fuel pump relay(coil side)->ignition key position, which is actived only when startingģ4 / Coil + and fuse->ignition key position, which is actived when key is in ON-position and START-positionġ08/ fuel pump->fuse->which is actived when key is in ON-position and START-position and Fuel pump relay->earthĪlso two fusible links I have changed to fuses and the fuses are ok.

Nissan OEM New Style Power Transistor Unit - PTU Only, Series 2 - Nissan 300ZX 90-96 Z32 147 99. Ecu lights up, when I put the key ON-position, but LED's turn off when I start. Nissan / Infiniti Nissan OEM 24168-40P00-KT Series 2 New Style Power Transistor Unit PTU Wiring Sub-Harness Only - Nissan 300ZX Z32.

I have tried with ca18 tps and z31 tps, and still no change. Does the ecu groung itself only through certain pins and not through the casing?Īlso is it possible that the missing engine accessories could cause the problem(like the air regulator)? Edited by Blobber But I have to go and check all the connection. I forgot to mention that I didn't use the relays which are original in 260z's electric system. Thank you SleeperZ for understanding my bad english.

My car does a short prime cycle as soon as I turn on the ignition, and then turns on the pump full time as soon as the engine starts. As I recall the Z31 operates the relay stuff differently so you may just have something operating in reverse of how it normally does. All I can suggest is to go back and study those Z31 wiring diagrams and relate it to the S30 relays. It's been a LONG while since I studied this, but I have a Z31 ECU and wiring in my S30. The ECU is not supplying the ground to the pump. The RAJ2810024H12HPD is integrated with a HIGHLY ACCURATE CURRENT DETECTION FUNCTION improved current-sense ratio accuracy in the current range lower than the nominal current, which enables the system to be built up for safe power management.The way I read it he has 12V on each pump terminal, meaning no voltage across the pump. Therefore, accurate current sensing is required when all loads connected to the ECU are operating or not. Switches for high current applications are used as power switches for ECUs in addition to directly driving loads. Highly accurate current detection function : New feature of RAJ2810024H12HPD The diameter of the wire harness can be reduced thanks to overcurrent protection and current sensing functions, which helps reduce the weight of the car body. Power distribution box benefits - By using IPDs instead of mechanical relays, power distribution boxes can become maintenance-free. Not only do IPDs protect themselves from excess power, but they also protect related components through wire harness. Intelligent protection function - The overcurrent protection function cuts off current to the load when overcurrent detection value is reached. A high level of reliability can be maintained even over prolonged use and maintenance is unnecessary. Moreover, since IPDs do not have mechanical points of contact, there is no deterioration of characteristics from mechanical wear. Power loss is also low compared to competitor products due to the low on-resistance, thus contributing to reduced power consumption of the ECU.Įfficiently drives large current load with low on-resistanceĬompact size and high reliability - The size is greatly reduced compared to an equivalent mechanical relay product. By using an IPD with protection/self-diagnostic functions built in, the number of peripheral components necessary can be reduced.Įfficiently drives a large current load with low on-resistance - A large current load can be driven using 1/40 of the current compared to a mechanical relay. Advantages of built-in protection/self-diagnostic functions - For safety, large current switches use components such as fuses and fault detection circuits, not just relays.
