Bit of a funny one last weekend. I bypassed the stock fuel pump controller and then blew the hose of the fuel pump on first crank.
at least I had another fuel pump on standby taken from a buddy’s scrapped focus.
So I swapped them over for now just to see if I can get it fired on the new ecu.
Unfortunatly it wasnt having any of it. I went through checking all the sensors and but it still wasn’t getting sync so no spark signal. I spoke to ME and tried a few other things to no avail.
It seems like something is interfering with the crank signal. I have spliced into the stock loom right at the ecu so it’s only about half a meter of my own wiring. It all looked fine but the logs were saying otherwise so I decided to re do the cam and crank wires right from the ecu to the sensor with proper shielded wire.
With new sensor wires done and layed across the engine bay (I’ll tuck them in the loom when the engine comes out) I thought it had a much better chance of firing up. The downside to running the crank and cam straight to me442 is that I no longer have a working dash. But hey that can be sorted at a later date.
My main concern was to try an get it fired up.
So I turned it over again and logged the crank trigger, still no sync.
I switched the cam sensor off in the software and unplugged it which seemed to reduce some of the fluctuations in the crank signal.
I thought I’d give it a try again so turned the injectors onto batch fire and cranked her over again. There was a nice pop then a bloody loud bang out the exhaust. But still no luck.
Went for it again then there was another bloody loud bang but this time I came from the engine bay and was followed with a lick of flames.
After a quick look about it was obvious what had happened. It back fired through the intake manifold and blew it clean off. So I called it a day on that and am now waiting for a response from ME on what the next plan of action will be.
I decided to have a closer look at the old cossi turbo.
turns out it has the .55 A/R turbine housing which is not a bad thing at all.
I pulled the housings off and marked a line so I know where it all lines up to keep some resemblance of balance when it all goes back together. As the turbo has been sitting in a damp shed for years you can see it really does need a good clean up. But still it looks like I’ll be able to bring it back to life.
as you can see someone has had it apart before and upgraded it with a 360 thrust washer.
I will still throw a fresh one in with a rebuild kit.
