[QUOTE="jarance, post: 331995, member: 21"] If the mechanic plug in the wrong HT leads, the engine would be firing on 2 out out 4. That means the engine rev would be very eratic. As mention by pussy, the timing belt can easily checked by open the cover near the distribution cap. If your timing belt is broken, the crankshaft will not rotate in proper sequence. The crankshaft sensor would not be able to detect the TDC and will inhibit the firing of the spark plugs and also the fuel pump. This is a fail safe feature to prevent further damage to your piston and valves. If the timing belt break while the engine is running, chances is that you may have a couple of bend valves or worst piston kaput. Best option is to do top overhaul. [/QUOTE]
