Had fuel pump replaced,car ran for about a minuet then quit,had all the signs of timing chain gone bad,Have no compresion on left side,should the car still start?,what else could they find when replacing the chain?this is a very spendy fix,my mechanic said he is 100% sure it is the timing chain that is the problem.Scence the car dose not run,how can he be absolutely sure?,Sorry for the slopy writing,im not good at relaying what the mechanic told me.what else could be wrong if the car cranks over but will not start?,Sensors?,Which ones?,Just lookin for some advice-help,Thank you
First, the timing chain runs from the crank around the gears on both cylinder heads. There may be 2 chains. What it does is keep the closing and opening of the valves "in time" with the compression and exhaust stroke of the combustion chamber (pistons).
No compression on the entire left side is not good. If right side is okay then you have 2 chains one for each side. Left side chain must be broke or damaged.
To check the compression without using air , someone had to turn the crank over. If this was done with a bad or broke chain you may have bent valve(s) as well meaning cylinder head rebuilding or replacement.
If you plan on keeping the car for a while consider replacing or rebuilding the engine.
