Problems with set up
 

Hi Richard. I'm having a few issues getting my hsf3 system up and running. I've everything installed but the system won't prime. When I put the sys jumper in nothing happens.
Also I turned 4the threshold down when I rev the engine the gauge cuts out and the water level light comes on and nothing from the jet. I have idc on the controller and map signal I've soldered the mps link and b for the flow map table for the single jet.

I've checked and double checked all wiring and piping it's all fine as far as I can see. You have wattsapp I can send you a video? Cheers

Is it a brand new system?

Re: Problems with set up
 

Yes bought it off you a few months ago was waiting on a few other thing for install so only getting it up and running now. Have a look at the video below I've since turned down (cw) the threshold and it's not cutting out so quickly. Still can't get the system to purge tho

Re: Problems with set up
 

good video.

Can you tell me:

1. Is the pump 's black wire grounded?
2. The size of your fuel injector?
3. The pump relay fuse is changed, why?

Re: Problems with set up
 

Pump is grounded to a bolt in the boot. Definitely a ground as the electric aerial is using it. Injectors are 540cc (upgraded to newer model Mr2 turbo injectors from 440) running at 80pc duty cycle.

I was just checking the fuse and replaced it with one I had there it wasn't blown

The pump and FAV worked when I fitted it up first. I had the red wire on 1St position ignition wire and it came on constantly so I changed it to a 2nd position ignition live and it stopped. Think it was getting 100pc idc at 1St position

Re: Problems with set up
 

Please measure the following:
(DVM scale set to 20V. Black probe to the GND)

Red probe to:

Pre-rank:
Pin 5
Pin 8
Pin 11
Pin 15
Pin 16
Pin 17
Pin 18
Pin 20
Pin 23
Pin 30

Run-idling:
Pin 5
Pin 8
Pin 11
Pin 15
Pin 16
Pin 17
Pin 18
Pin 20
Pin 23
Pin 30

Check this pin when blipping the throttle for voltage drop:
Pin5

cheers Richard. will do this this evening and let you know the results

Re: Problems with set up
 

Hi Richard these are the readings I got:

Pre crank:

5. 11.66
8. 12.00
11. 7.68
15. 4.94
16. 0.02
17. 0.00
18. 0.01
20. 1.71
23. 9.62
30. 0.02

At idle:

5. 14.14 blip throttle 14.16 voltage increase
8. 14.06 - 14.13 fluctuates
11. 8.88
15. 4.94
16. 0.10
17. 0.00
18. 0.06
20. 1.99
23. 11.77
30. 0.02

Re: Problems with set up
 

It appears the 12V power is not received by the controller. Where are you connecting the red wire of the power connector to?

Re: Problems with set up
 

I had it on the cigarette lighter but that was 1St position so I found a live going to the fuel pump. I checked the live and it stays at a constant 14v

Re: Problems with set up
 

i'm going to try connecting the black and red wires somewhere else. i'll try the heater fan controls they are on key second position. i'll let you know how i get on

Re: Problems with set up
 

also check the red and green wire of the grey are not reversed at the fuel injector splice.

Re: Problems with set up
 

will do thanks. i have checked these i'll double check again. made the mistake of using a phase tester instead of a multimeter on the green injector wire and engine spluttered a bit (opened injector fully) and getting between 2-4 volts on the blue map sensor (will confirm)

also just to check, what readings should i be getting on the 2 signal points on the pump relay with the sys jumper in and out? meter points: black to earth in boot , red to 2 points or meter points: black to blue , red to red?

cheers

Re: Problems with set up
 

Can you measure pin16 while blipping the throttle.

Re: Problems with set up
 

hi Richard i've been away for a few days i check this later. thanks

Re: Problems with set up
 

Hi Richard I swapped the red wire for the controller as you suggested and it worked!!!! System is priming now putting it back together to take it for a spin make sure everything is OK. The wire I used turned out to be the low fuel light wire and wasn't a steady live

Re: Problems with set up
 

Thanks for the update.
