A bit of background:
I’ve recently changed both gearboxes and have been working on a few gremlins from that - mainly shimming the CPS.
Yesterday, I found that the engine hit a brick wall around 3,000 RPM. A bit of research pointed to the turbo related bits.
Now, I drove it back home keeping around 2,000 RPM and it ran ok. I then got on with fixing gremlins from gearbox change, sticky gearshift and handbrake switch. I know now that I left the handbrake switch unplugged but aside from that, no other electrics touched.
I moved to the engine bay and found a small hole in a vacuum hose from the turbo modulator to the metal pipe below, so I cut off the end and re-attached. I also unplugged a couple of plugs on the air box and inlet hose. These were re-attached.
I went to start the engine and it cranks fast but not a hint of starting. I say it cranks fast because I’ve heard it cranking more slowly whilst having problems with the CPS and the shim.
I know I have problems with the CPS and I’m waiting on a new plug so I can make up a new cable but, it seems strange that the starting issue now seems different to the issues when I had no shim under the CPS. It would try to start then and cranked more slowly - at least to my ears.
I’m going to increase the thickness of the shim and renew the cable and plug but are there any other ideas as to what other reasons might cause this fast cranking with no attempt to fire?
I have Nanocom and will check injectors, fuel pump (recently changed VDO) and cranking speed over the weekend.
