Hello guys,

I have been having problems with my sr swap, and that is it wont start. Earlier the starter wasn't turning over so I was confused cuz it was working fine before. So i gave my dash a swift kick in the driver side and the starter started turning over, i assume that was caused by the ignition/starter relay being stuck. Either way this was no break the car still didn't start.

BATTERY IS WEAK!

What the car has:
- 1989 240sx
- greddy intake plenum
- megan tubular
- gt28rs turbo
- 3 inch from turbo back
- greddy big fmic piping (piping hacked together)
- greddy type s blow off valve
-
I began my diagnosis and began hunting down the problem and this is what i have done/checked off:
- 12volts on all plugs
- have spark
- have fuel pressure in spec
- hear injectors clicking, but injectors not spraying

The stuff what is not connected ect:

- rad is not on
- vacuum lines not fully connected
- maf not connected
- aicv and knock sensor not connected
- wastegate/bov disconected

Questions i have:
- what exactly is the orange wire and what does it do and tell the car to do and what voltage is sent to the ecu from this wire?
- ignition relays what are they for what do they control
- can injectors fire with a weak battery?
- can injectors click but not shoot fuel?
- how come even with a fully charged integra battery the car still doesn't turn over at full speed? its very sluggish?
- how come when i crank the car the ecu light doesnt come completely off it starts to flicker?

Im begging for help i was in an accident and i need a car the car i was in was a write off and i want to take the money and fix this one.

connect all the things that aren't connected.

-what orange wire
-the "ignition relays" control everything
-get a new battery and stop asking questions about how things work with a weak battery.
-injectors can click but not shoot fuel if you plumbed the fuel lines backwards in a desperate attempt to rush a swap.
-If a battery is junk you can charge it for a month but it's not going to crank the car properly.

Stop rushing, buy an fsm, do work.

If you want to ask more questions post the serial number from you fsm first.
