My car was off the road for 3 months with a blown head gasket and iv finally got it back together and going again but now my ABS and 4WD light on the dash is constantly on

Iv found that the 4WD relay under the bonnet isnt getting its +12v switch so i ran a wire from the battery to the power out pin where the relay plugs in and the abs unit seemed to spring to life and the ATTESA ecu finally started showing me some error codes (21,61,62). i Started the car and the abs light come on after a few seconds then a few seconds after that the 4wd light come on again.

So obviously im not getting any power to the ATTESA ecu or ABS unit all because im not getting this IGN +12v switch to the relay, Also the the +12v that feeds the relay is only getting 11.5v when the battery is showing 12.7v

While the car was sitting i accidently left an interior light on completely draining the battery so i replaced it with a blue top optima

Im out of ideas as iv tripple checked every fuse and cant find a dud ? a wiring diagram would be really handy

      I don't know it is due to that. It could just be due to load on track being more than a dyno. But it would be nice to rule it out. We're talking a fraction of a second of pulling ~1 degree of timing. So it's not a lot, but I'd rather it be 0... Thicker oil isn't really a "bandaid" if it's oil that is going to run at 125C, is it? It will be thicker at 100 and thus at 125, where the 40 weight may not be as thick as one may like for that use. I already have a big pump that has been ported. They (They in this instance being the guy that built my heads) port them so they flow more at lower RPM but have a bypass spring that I believe is ~70psi. I have seen 70psi of oil pressure up top in the past, before I knew I had this leak. I have a 25 row oil cooler that takes up all the space in the driver side guard. It is interesting that GM themselves recommend 0-30 oil for their Vette applications. Unless you take it to the track where the official word is to put 20-50w oil in there, then take that back out after your track day is done and return to 0-30.

      Nice, looks great. Nice work getting the factory parts also. Never know when you'll need them.

      I take it that the knock retard is from bearings tapping a little tune? Thicker oil is a fragile bandaid. You need a much bigger oil cooler and probably the bigger pump being discussed.

      Hi @Chupapy i had several leaks from coolant pipes being corroded, i also had one leak on back of the head onto transmission. For me that leak was from the turbo water line. Follow the line to the back of the head The hose and metal pipe had perished these are the best pics I took of it at the time
