Just a quick teaser for you all.

I just got it running again after the VATS had locked up the PCM. This morning fired it up to bring it back into the shop, just couldn't resist a little play time.

Small update

Since disabling the VATS I've moved onto the cooling fan controls as I can now program the PCM to control them. I bought a couple of PICO relays and sockets. I used jumpers to temporarily make all the connections. I simulated the ground signals of the PCM and the relays operated the fans. I soldered and shrink tubed everything and started the engine. I was watching my scanner for the magic temp to arise but nothing happened. After it passed the required temp by several degrees I decided to investigate.

I've done many many relay installations, and so far on this I've not had one circuit that I've wired wrong.

I check the relays for and the PCM wires for ground, all was good. I pulled the low speed relay out and checked the socket connections for power & ground. The power in connection was dead. I checked the relay and it had fried itself. The 25 amp fuse was still good but the relay was toast, and it burned the socket connection.

I went and picked up some Hella relays and sockets, much better quality. Rewired the new relays and everything's a go. The fan on low cools the idling engine down from 93șC to 89șC in less than a minute. With the hood down the fan is hardly noticeable.

Now I've got just the speedo and tach left to wire up and I'm done under the hood.

I've got several little things to tidy up and it'll be ready for the road, maybe another couple of weeks.
