86 civic B16 on its way!
hey all i have just completed a b16a1 swap into an 86 civic but it wont start :-( i bought the engine, gearbox, full car wiring loom and ECU that came from the doner and it just wont go!. im a mechanic by trade so i know what im doing when it comes to fitting and wiring etc but i dont have that much knowledge on the honda ecus.
all earths are correct and present
all lives and ign lives are correct and present
the relay module clicks with ign on and when cranking
fuel isnt a problem as its running a standalone fuel supply self fused and is running a 205lph pump
i have no spark or fuel injection so my guess is that the ECU is not switching on.
i have tested as many values as i can going in and coming out of the ecu and everything is as stated. am i missing something major here? do these ecus require every sensor to be connected before they will start as there are a few i do not have, these being
lambda sensor (planning on using an LC1 wideband)
i dont have the valves which connect to the vac system, i think they are fuel purge valves but not 100% on that. also im not sure if this engine is supposed to run an IAT sensor as i don't have the original air box and intake pipe. erm i think that's it oh sorry forgot to mention the engine itself, i have fully stripped and rebuilt the engine including new bearings headset cam-belt kit the full works, all timing marks are aligned as they should be and tensioned correctly. everything i do and check just keeps pointing back to the ecu, i cant get hold of the guy who sold me the engine as hes in the army but iv got a feeling the ecu is ok and is missing one thing from somewhere.
anyway any help would be much appreciated as i need to get it done over Christmas. i need to do some testing as its my university project and it will be receiving a turbo soon after
thanks again
