Our park ave. Has had starting problems for about 4 months. It usually wont restart for a few hours or up to 3 days. I have replaced the coil & ignition module, which did not help. It cranks over good any suggestions?

Does it start up and run fine that whole day or whole week untill out of the blue it sjust stops?

When it wont restart check for spark and fuel pressure.

The car seems to lose spark when it wants to. It ran fine to work but after 10 hrs of sitting it failed to start, waited 4 days before it would restart again. Most of the time its 3-4 hours though. Is a sensor on the crank bad?

It could be a bad crank or cam sensor.

But it might be a distributor pick up coil or a bad rotor or cap. Check over your distributor first.
