Re: Startup issue, Will not start without starting fluid.

Went to make progress on startup from yesterday, and got the battery nice and charged. Plugged in the PC, hit consult and synced from ecu >>> PC to Check the maps from yesterday and watch the display when starting. http://i38.photobucket.com/albums/e133/tkovatis/Fairlady%20Z/Tuning/nistune2.jpg http...

Re: Startup issue, Will not start without starting fluid.

While I appreciate the response, I don't think you are reading the post carefully prior to responding. It is a 1988 NA ecu ( High impedance) with DSM 450 cc Injectors ( Low Impedance). Has idle controls, and the battery is new, just slightly discharged. Also it is late spring here (warm) 1/R1+1/R2=1...

Re: Startup issue, Will not start without starting fluid.

If you battery can't hold over 11.0 volts for 10 seconds that it takes to fire up I doubt it's up to the task. without any idle control system you need to either drill a hole of about 1/8 inch (start a fraction smaller if its a 4 cyl) in throttle plate or just find a way to screw the throttle plate...

Re: Startup issue, Will not start without starting fluid.

Figured as much. Power wire is 2 ga @ apx 7', ground is 4 ga @ 12"s. Since that last post I had charged it back up to a 11-12 volts cranking. Some how the fuel map got FUBAR and was super rich (9:1) I have no idea how that was possible, as I double checked it last week. Fixed that and car idled...

Re: Startup issue, Will not start without starting fluid.

Didn't get it to start as of posting. Without cranking voltage is at 12.2V. Battery voltage dips between 9-8 volts when cranking. Would the Resistors, combined with the battery trunk relocation and this voltage prevent start up? I'll need to leave it on the charger for a bit before I try again. Also...

Re: Startup issue, Will not start without starting fluid.

I'm having the same problems Jitter did, but I had already rewired my Injector harness to pre campaign and added the resistors for the DSM injectors. Injectors were resized. When the MAF is unplugged and battery has good charge the car will idle up to 2000 rpm. When I Plug the MAF in it will not idl...

Re: Fuel Pump Not Priming

Car still isn't running, but that may be unrelated. With that in mind; When I turn the car to on, the ecu powers and blinks, fuel pump primes Then one of two scenarios occurs. 1. Turn ignition to off, ecu does final blinky thing, tung ign on, ecu powers and blinks, fuel pump primes. or 2. Turn ignit...

Re: Fuel Pump Not Priming

I rewired my fuel pump to bypass the ecu and it primes now.

Nistune connects
Lights Blink
Fuel Pump does not prime.

I was considering rewiring the pump, but that's a sad work around. I'll get to some trouble shooting if it's relatively nice sometime this week.

Interesting.

Where was this "splice"? I have a plan of attack, but thats not on list.

Opened up the ECU and examined both sides. I don't see any bad connections. Made sure everything was seated. I have a new CHTS sub harness and was ready to start the engine after sitting for a week waiting for the part. ECU turns on but fuel pump no longer primes. Slight taps on the ecu housing like...
