I plugged the laptop in and checked the throttle position sensor voltages in the week, and they were indeed wrong. I pulled the sensor off and filed the mounting holes slightly so that I could adjust it. A few quick checks, and an adjustment of the throttle cable gave me the correct readings for closed and full throttle. It was late at night when I did it, so I had to wait till the next day to test it and it ran and returned to idle with no problem. I noticed that the number 3 header tube was cold tho, so I had a misfire to trace. I pulled the lead and put a spare plug on and it sparked with no problem, and the injector had voltage when it should do. I thought it may have been a dodgy plug lead, so I decided to fit the MSD before I went any further. It fitted neatly on what was left of the fileer panel so I drilled it and bolted the MSD in place.

I turned the inlet and MAF round at the same time, and wired it all to fit. Once it was done, I fired it up again and still had no number 3. I swapped the wire out even though I had checked it once, and that made no difference. The only thing left was a dodgy injector. I disconnected the fuel pump and started it up to drain the fuel pressure, then pulled the rails. It was still full of fuel so was a messy job. I swapped 1 and 3 and the problem moved with it. So one of my brand new spare injectors is duff. I had a set of 19lb (they shoudl be 24lb) or the 42lb ones for the blower. I swapped the 19’s in temporarily and re-flashed the computer and it fired up no problem on all 8. I was concerned it would get lean, so I wasn’t happy leaving those in. I swapped in the 42lb ones and re-flashed and could not get it to start at all. Got a few impressive fireballs out of the headers but that was it. I disconnected the pump and it ran till it drained the rails, so it was still overfuelling. I need to find the correct timings for the new injectors as they are super fast ones, so more research needed. Apart from that it was more wiring, this time the neutral start switch and reversing light. I’d forgotten a relay so will need to wire that up as well. Coming on though.
