Micra K11 Blog Entry 022

So today I sorted out the PAS reservoir bracket and made a bracket for the airbox, but the breather hose coming off the rocker cover is very very close to the mounting hole so I've left that for now.

Adjusted the throttle cable leaving the airbox off incase I needed to adjust it more....car wouldnt start even with some throttle. Perhaps the throttle cable was too slack, so checked again and had it so there was barely any slack....nope it stiill wouldnt start.

We had a pretty sharp cold night (not sure if there was any frost but it was certainly cold enough to) perhaps the harsh cold had gotten to the battery? The battery was replaced the day I started to strip the engine bay, having put it on charge before the previous update I knew the battery was in good health. I tried jump starting it to rule out the battery, it had plenty of cranking but not firing.

I disconnected the 1.4 auto ECU and key transponder and refitted the original 1.0 ECU and transponder, it fired up straight away.

This was mind boggling. The car started and ran numerous times 4 days prior, got upto temperature and cooled down when I was checking for leaks etc etc The only thing I had done was adjusted the throttle cable?!

Either something is fried inside the 1.4 auto ECU or something has happened to the NATS (Nissan's factory immobiliser)

The Engine Management Light is back, we know it can't be CVT gearbox related because its a manual transmission ECU. Plugged in my OBD2 reader and no faults are found, cleared the code and the light disappears. Switch the engine off and read the ECU again, no codes found....bizzare

Anyway....

With the car running I got it moving for the first time and parked it on flat ground to check the fluids. A small top up and we're good to go for a test drive. I drove round a 1 mile radius, temperature stayed half way, EML still on but I'll ignore that for a second. Shifting gears around 3k while I bed this new clutch in but its changing gears smoothly and the clutch bite is good.

Parked up outside the house to check for any leaks and there wasn't any. This gave me an opportunity to finally clean the driveway of transmission fluid

I didn't fix the leaking exhaust manifold because I received confirmation of shipping of the new Gizfab 4-2-1 Manifold, woohoo! I'll persevere with the blow until the new one gets fitted next week at work.

The engine bay still needs some tidying up and some paint touch ins but its now running and driving and those things can come as and when (I've got an R34 to fix next)

Now to get some miles on the clock and get this clutch bedded in. Its gonna be torture not putting my foot down properly especially when the new manifold goes on but it'll be worth the wait!

Next up... brake upgrade (I've got the parts I didnt want to bed a clutch and brakes at the same time)
