Measure the voltage at the coil coming from ign sw while the car is cranking. If it drops significantly below 5.5 and gets close to 5v the spark will be weak and car will most likely be very hard to start. If it does drop cause could be too small of cables, battery capacity, dragging starter or bad/corroded connections.
