READ THIS MAYBE YOU CAN HELP The car is a 92 civic CX hatch with a 92 sohc vtec motor with the Si ecu
Some one installed the Si motor and did not run the 4 wire o2 senser,
and the vtec wiring to the ecu.Im going to do that tomorrow.
The gauge cluster(CX) does not work either,it lights up but none of the gauges work (fuel,speedo,temp,turn signals),the fuel pump is not getting power unless I put power to it(changed the main relay,fuel pump, and still did not work & checked all fuses)I jump the fuel pump wire and it will run but dies when you drive normal.The fuel pressure is at 32-37psi jumping back and forth,will not stay steady.The owner said the fuel filter was less than 2 months old.It has all the original CX wiring.......
IF Anyone can help please do
