JDM trueno not starting. need help!
OK, so some might have seen my build thread. just got everything back in and its not starting..

Car is a 1985 JDM Trueno. Car DOES NOT have diagnostic plug.

so story so far: the gets spark, and gets fuel (kinda) and will crank over and over. Have followed the guide and set crank to 0Deg TDC for piston 1, check intake cam mark and set the dizzy to the correct markings also so timing SHOULD be good. fuel is getting to the rail but i don't think the injectors are firing. swapped over to injectors that i know work and still nothing.

Now given that I've only done about 50miles in the car i didn't really know what the fuel pump sounded like on ignition start up. i bridged the yellow 'T' plug and switched on to ignition and the pump started pumping. turned over but nothing (i do think this is down to the battery going down)

I flashed the EML light and it came up with 4 and 6. now being early spec i believe there is only 11 codes meaning that the codes are 4- coolant temp sensor signal and 6- RPM signal


1 All systems normal
2 AFM meter signal
3 ignition signal
4 coolant temp sensor signal
5 O2sensor signal
6 rpm signal
7 tps signal
8 air intake temp signal
10 starter signal
11 switch signal (AC switch on. ECU faulty) * ( INFO FROM CLUB4AG)

Earths I have taken of to clean are 2x gearbox, 1x head earth, 1x block earth, 1 x intake earth and 1x earth behind engine bay fuse box.

EFI rely in engine bay is working fine and so does the 2nd one in the drivers footwell.

im not any way electronically minded but am sure I've covered the areas needed done.

Any suggestions?
