GOLF MK2 20VT CONVERSION AUM FUEL PUMP RELAY HELP

Hello hope someone can help doing a mk2 ce2 1.8t aum swap std managment ,done a couple before that started first turn of the key so was kinda expecting this too lol but sadly it turns over but isnt starting i couldnt hear the fuel pump priming , so tried changing relay ( 167) then used the 18 relay to bridge ( thanks rbj) and fired up right away . But will not start with the 167 relay anyone any ideas what could be causing this ( the immob is defeated) what does the 18 relay bypass??

 

I’ve just been having a similar issue but on an ABF working with Omex 600. The 67 relay needs a signal from the ECU to prime and then run continuous once cranking. It’d be worth checking you’re getting the ECU signal to the blue and yellow wire in the back of your fuse box. The 18 connects it all permanently so doesn’t need the ECU signal

 

Thanks for the reply , yeah i will check that but i think i may have missed something as accelarator pedal isnt working either ,i havent wired diagnostic port i will do that Monday and go over the wiring again and check the ECU signal wire

 

Fusebox is ce2 and wired too g1/3( and pretty sure fusebox itself is good as out a running car and latest ce2 car i had,2002 Caddy still has all it original fuses and no sign of heat or water damage) i will try the 409 relay .
Ive not wired in the clutch and brake switch but i wouldn't imagine they cause any issues with fuel pump relay but i will wire them in today along with diagnostic port. Cheers and thank for help

 

The ecu signal wire was in g1/4 instead of g1/3 doh ,starts fine now . But the accelarator pedal is still not responding , only codes are ones youd expect with a conversion . Im going to go over wiring again today and hopefully find the issue

 

Can anyone confirm the T14A pins 5 6 8 are all live feeds i have them all fused to Z1 is that an issue should they be all wired to different pins , ive still no accelarator pedal,starts and idles fine ,only unusual code is 16621 ( ive swap map sensor) i only have down pipe fitted no exhaust

 

Thanks for the quick reply its an AUM i have t14a pin 5 pin 6 and pin 8 wired into Z1 with a single fuse ,should the pin 8 purple and black only be wired on AGU

 

I have an ECU coming tomorrow to try too

 

I checked pin 121 is live at harness with ignition on thanks again for your time

 

Yeah your right no pin in other plug remove it, ordered an ECU but lost in Wales somewhere .
There is a brown wire with red tracer on the 2nd loom( bigger ecu plug) im sure it earth in scuttle on mk4 can anyone confirm that and if needed

 

Yeah i had it on the battery but just clutching at straws now , hopefully postman will find and deliver ECU so i can rule that out now. Thank again for your time

 

Got my new unlocked ECU and still same no accelarator pedal , ive went over everything all seems right ,only thing im bit unsure of is the ignition switch, vaguely remember having to change a pin on one several years ago , i appeared to have a 5pin switch but loom is 6pin( i converted to ce2 and used bunch different looms) ive tried 6pin ignition switch with no difference, does anyone know if there a pin/wire that needs moving ( may have been mk3 or Corrado ignition loom) ??

 

Okay thanks
I am getting 16621 code which i assumed was due to no exhaust ( just 2.5in downpipe, waiting on system coming)if i clear it and rescan before starting the engine it still there so im guessing this is the issue

 

And i did try changing the throttlebody and the map sensor aswell as n75
