So I recently built a 1.5JZ thats going into an S14.
I just had a custom harness made by chasebays, and wired everything up this week.
Now the engine will crank all day long, but not start.
After going through the engine Ive realized its not getting spark or fuel.
Im looking for any input or ideas on this. Ive been searching and troubleshooting all week so now Im looking to see if anyone can point in a direction for anything I might be missing.
Some info about the engine:
1.5jz using a 2jzge block, stock 1j head
Im running an aristo 2j ecu
I have an AFPR
Walbro 255 pump
everything else is pretty much in stock form.
As far as wiring the only things I dont have plugged in are the O2 and the IAT sensors because Im waiting on those to arrive.
I am just trying to turn the engine over to make sure it starts right now before I have it finished so there is no intercooler or intake on the engine yet.
As far as diagnosing the problem so far I have established that the ecu and ignitor is getting correct power and ground, the coil packs have been tested to be within spec at 0.8 ohms, and they are receiving 12v of power at the plugs. I tested the ignitor on another 1j so I know its good.
The fuel pump works and I get constant fuel pressure at 43psi.
When I crank the motor over injector 2 give one spray of fuel right away then nothing from any of the injectors.
Im leaning towards the problem being in the ecu or possibly cam sensors?
I cranked the engine with and without the ecu and it did the exact same thing without the ecu.
Does anyone have any ideas about this?
