Sunday, could be the day I start the engine after the Cerb being off the road since November 2014 for a new chassis!

I'm trying to think of anything that could go wrong.

Primarily I guess it's fuel and oil. I've gone round the car and checked all the fuel hose connections and all seem ok. I need to remember how to start the thing, but ignition button on, then disarm the immobiliser, then the fuel pump should prime the system. At this point I'll check around the car for leaks before starting.

Engine oil. I tried when re-connecting everything to fill the pipes with oil etc, but with little success. So, I'm thinking can I disconnect the coil pack leads (odd and even). Move them out of the way to stop them sparking off something. Then start the car, the engine won't fire, but it'll turn over pumping oil round the system. Are there any problems with that approach?

Gearbox oil is full, so is the diff. I'll check the electrical connections around the car.

I do need to fill it with coolant.

But, apart from that anything else? Feel free to comment, I'd rather look stupid than have broken Cerb.

Thanks smile

Generally the engine won't get up enough speed to prime the oil pump on the starter. I went through agonies trying to get mine to prime after my body off, nothing would work until a highly experienced engine builder told me to just start it and if the pressure didn't come up in 10 seconds then stop it again. Sure enough the pressure comes shooting up after the longest 5 or 6 seconds in your life.

old school was to build and lubricate at the same time using a lubricant 'enhancer' like Wynns or STP then crank a few times for 5 or 6 seconds at a time with the plugs out (so spins quickly). Then start and don't touch the throttle til the pressure gauge shows at least 30psi.

I think I'd still do something similar

If you chose to ignore Peter's advice, then prime without compression by removing plugs as per Magpie's advice rather than without ignition.

Started mine in similar circumstances both ways, and Peter is right, it is a very long 5 or 6 seconds. Still not sure which is best because although you don't see the pressure gauge move on the starter, it seems likely that there is some oil flow.

Good to double check everything first, my heart sank when I found I had no power steering - thankfully I'd simply forgotten to refill with PS fluid.

As above - if you do prime it by starting then do NOT rev it until you have pressure on the gauge and the light is out!

Well it's good news, it only bloody started. Tried the coil leads off first just to try to get some oil moving. Then went for a proper start. The pressure came up after about 5 long seconds and all is good.

I'm a very happy chap. rofl

Thanks

Brilliant! It's a great feeling when it does all come back together and start. Well done.
