    Starting up v8 93

    Hi gents I recently pulled apart rover v8. Replaced rings bearing timming chain and camshaft. The vehicle has trouble starting. Vehicle has spark on spark plugs. I cranked motor over and compression confirmed when timing mark comes up on pulley.distributor seems to be pointing to no one ht lead. I believe I have correctly installed timming chain with its pointers pointing to each other. Camshaft seems installed corectly as compression comes when tdc comes up to its pointer. Hmm ... any ideas gents? ive checked if fuel is getting to fuel rail and it is from the overflow. Any help would be apprecisted. Thanks in advance

    Double check your leads are going to the correct plugs. It may sound obvious but sometimes it is the easy things.

    Just as an aside, it would have been worthwhile to check cam timing with degree wheel and DTI rather than just chucking everything back in lined up "dot to dot". I used a Rollmaster duplex timing kit with multiple keyways and had to run an indicated 4° advance on the crank gear to achieve true factory timing on a standard Rover 3.9 cam. Who knows what the outcome would have been in my case if I used standard timing components and put it back without checking.

    To second Jazzman's comments I think there was someone on here not too long ago who had the leads in the right order, but fed to opposite banks. Leads 1/3/5/7 were actually going to plugs 2/4/6/8.

    Just give it a good long crank from a jump start. If you've got fuel and spark but just timing of cam or leads wrong, it will either give the odd cough or a backfire or something. At least then you will feel like you are getting closer! My favour trick is just rotate the distributor while its being cranked.

    Last time I had the distributor a full turn out. It was firing on no 1 on no.1 TDC exhaust stroke rather than compression stroke. (just laziness, 50:50 chance!)
