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.
