Bleah just got home. Kent lives diagonally across the other side of DC from me so longish slog home.
The issue was the integration of a 95 RRC ECU harness to an old 4 banger wiring ( air quotes) "harness" full of PO hacks.
We went thru things one step at a time. Got power to the harness then the fuel pump then the ECU. Found good places to tap switched power.
Sorted out a bad ignition module wire. Lit the fuse and it went bang.

It was a combination of MANY wires needing to be connected to the correct places. Im not nearly knowledgeable enough about "modern" engines (ie. anything fuel injected) to be able to adequately explain in further detail.

Bill will have to chime in. I cant thank him enough for all his help.

Edit: Looks like he beat me by a few seconds

Having had so many problems with my V8 and seeing the problems others are having that sound so similar but aren't....makes it tempting to go diesel...

Honestly it wasn't really anything all that bad. Part of the process of any engine swap.

That's great news!
I wonder if a 87-88 RRC harness would have made it simpler since it does not have the bells & whistles of a 95. Just a thought for future conversions by others.

Well, we got the engine running, but after 15-20 seconds it chokes itself out like there is too much fuel being pumped into the cylinders. Stock injectors are in. Brand new spark plugs are caked with black carbon. What's the timing supposed to be set at? How many degrees advanced or retarded?

Book says 6 Before.... I think I'm around 10-12... but I have an aftermarket cam.

Does it fire up straight away or struggle?

I wonder if your external fuel pump is over fueling. I'd test fuel pressure and both the coolant & fuel temp sensors. Also your MAF may need adjusting too. All three of those can cause a rich running condition.

Sounds for sure like a bad or disconnected fuel pressure regulator. Check the vacuum line at the back of the plenum cover that goes down to the regulator

In that video, the only input is when my dad pulls the throttle.

Timing is in range, and all vacuum lines are good. I suppose next step would be to replace the fuel pressure regulator.

No exhaust = no back pressure= runs rich. I think before you over think this you should install an exhaust. I have had major exhaust leaks on rover v8's and the trucks ran much smoother once an exhaust was installed.

I agree get an exhaust on it before jumping to conclusions, but you should also stick rover gauge on it and see what it says.

We will be trailering it down to an exhaust shop within the next few days.
