My 1987 Volvo 740GLE non-turbo was not starting. I replaced the engine wiring harness, coil, and power stage module. The car still did not run. I asked a mechanic to take a look at it and, he immediately found the problem. The timing belt was broken and, upon later investigation, the mechanic replaced the timing belt with a new one and, the car attempted to run but did not. The car had broken the new timing belt and several of the teeth on the lower wheel were missing. The mechanic does not think there is a problem with the crankshaft or pistons. He believes the problem may be at the overhead cam area. Does anyone have any suggestions?
