So my hatch was bogging on the way to work. i got there parked and i did'nt start up again. towed home.
timing is set.
TDC, cams out, cyl1, comp stroke top.
code 11.
plugs have fuel.
there's spark n compression.
i've checked harness, ok.(continuity)
injectors in spec. cps passes tests for volts and continutity

my question is the CPS tells ecu when to fire injector right?
cps in plug wire 1, injector 1 fires.
then 3, injector 3
then 4, injector4 and so on.

I've disconnected all but 3rd injector rotated cps and injector clicks more than once during a full turn.
Should it?

gonna assume 91 ka24de right?

KA24DE Firing order 1-3-4-2
Distributor rotation: Counter-clockwise

It should fire at these degrees
0
540
360
180

same as SR20

Seems like it clicked 2x, should it be 4x?
Well I received new dizzy, will update with results in a bit.

it did that with old dizzy, so back in it goes.
code 11 also passed.

soryu · 12-11-2015, 04:00 PM

Plugs are wet
Injectors in spec (ohms)
I'll check for continuity, leaks and pulse.

soryu · 12-13-2015, 04:26 AM

Passed injector tests also checked ecu relay and harness everything OK.
Erased codes still no start n no codes .
Getting 55

soryu · 12-13-2015, 07:15 PM

well my injectors were 11,11,11,12.ohms
12ohm injector is cyl1, i noticed the solenoid on top of injector is bent??
i tested fuel pressure when pump is primed pressure up to 40psi settle to 30.
i noticed after a couple of minutes went down to 20.leak??
threw in some starting fluid without without fuel pump fuse, sounded like it was about to start. threw fuse back in, no start.
i have tested fuel pump it is within spec 0.5ohms. im going to swap it out tomorrow c what happens.

soryu · 12-14-2015, 04:54 PM

Threw in some starting fluid, car starts and dies.
Got code 21.(ignition)now.
Recheckin fsm.

pinkyrang · 12-14-2015, 05:30 PM

soryu · 12-15-2015, 03:10 PM

threw in new fuel pump, no start.
code 13.

soryu · 12-26-2015, 02:38 PM

Polarity was reversed on new pump.
Corrected.
Car running now
Getting the timing down took a while.
What's up with all those codes?
