You have a 1991 Plymouth voyager se and it turns over but wont start we have checked all the fuses and cant seem to come up with anything we checked for spark and have none what else should we check?

Go back to the basics, look at fuel delivery, ignition and compression. If you have all 3 and everything is adjusted properly, the engine will start. Try spraying a little starting fluid into the air intake while someone is trying to start the engine. If the engine briefly catches while you're spraying starting fluid, the problem is fuel delivery.
