ITBs Starting Issue

[tomboi24]

Hi guys don't seem to be getting anywhere with this, I have just fitted ktec itbs with gen90 on my PH1 made all the pin changes on the loom to match the gen90 and re-wired the penny-giles TPS into the oem loom. The relays, fuses and kill switch are all working as they should but I cant get 12v at the coilpack plug and the fuel pump isnt priming unless I cancel out one of the relays with a piece of wire and hey presto everything comes to life, and the car will run. Here's the pin changes from ktec the two 38s in destination pin confused me slightly. Its the only place I can think something has gone wrong as the car ran perfectly before.

Any ideas guys much appreciated.

Feed to fuel pump and coil come off the same relay so it sounds like the ecu isnt dropping the earth to it. Check you have a live and earth on relay pins 86 and 85. you will have one of those missing and that will help find the fault.

im assuming you are bridging pin 30 and 87 (on relay)to get fuel pump run?

Yes that's correct, I will check those pins thank you mate.
