Hi Everyone i am in the process of doing an ecotec to LS1 conversion on my vx sedan. I bought a donor wh statesman to do the swap. I have done the swap already but i am having a few issues I am wondering if you all can help.
As far as the swap goes it all went pretty smooth with fitting and it fired right up.
The the donor car was running and driving with no issues before I pulled it out with no lights other than airbag on the dash
The car runs and drives and the first issue I came across was my oil pressure light wasnt going out. I was confident it had pressure as the lifter tick went away shortly after starting and the oil level had dropped from being slightly over full down to with in range. So i ran down to supercheap and bought a gauge and put in it and I am getting oil pressure. I then fininshed off a few little things filled it up with water and warmed it up and I noticed my water temp gauge isnt coming up. I also have an engine light on as well.
I am wondering if there is some kind of wiring issue between PCM and BCM/dash as all these sensors were working before the swap in the donor car. I have checked all connections as well
I am using the dash out of the donor car and I had a local performance shop disable the VATS on the pcm so it would work with my bcm but I am also having a minor issue with starting. Usually the first time I turn the key the engine doesnt crank at all then the second time it cranks for a split sencond but stops then usually the third of fourth time it cranks fires and runs fine.
Any help would be much appreciated.
I tried to do as much reading and research as possible before hand and got everything i needed and thought it would be pretty straight forward btu im not surprised im having issues as murphys law says anything that can go wrong will go wrong.
cheers guys
