1991 Suzuki Swift 4 cyl Front Wheel Drive Manual

My Swift has spark, has fuel, timing belt turns, camshaft moving, zero compression, won't start. Could the timing belt be out of time? Or could my problem lie in a sensor?

Do you have zero compression on all cylinders? Did the belt snap or has it jumped teeth? Even if the timing was out you would still get compression at some stage in the engine cycle. It's definately not a sensor !

Let me know

I have zero compression on all cylinders. The timing belt is in one piece and spinning. It ran like a dream, then one day just stalled and wouldn't start again.

Check all the teeth on the belt are intact (no gaps) not stripped anywhere... I suspect the belt may have jumped some teeth on the camshaft (is it tight)and maybe bent valves ... if you have no compression on ALL cylinders you must have a bad valve in each one ... or your piston rings in every cylinder have gone bad .. but all at the same time ?? you are going to need to strip the engine down to locate the fault i'm afraid ?

let me know
