Ford aerostar no fire to plugs.?

1988 Ford Aerostar gets 11v from coil but no spark from plugs. Getting gas to engine. Changed distribuitor, rotor, tried a different plug. It happened suddenly one day it was running good then the check engine light came on as it cut off. I tried it a few times with no luck. Sat for 10 minutes tried it again - it ran all the way home. The next morning I tried it again and it just cranks won't turn over since. Rotor spins; serpentine belt turns; there are no points on this model year. Did not change the condensor or wires however using a digital volt meter I could tell there was current present. 11.4v at the battery. It ran good no smoke or backfiring. (I thought about the timing) Some other threads suggested it might be the relay but I can't see how that can be.. Can any one Help?Ford aerostar no fire to plugs.?
Have you tried the ignition switch? This could do what you are speaking of. There are alot of wires that engage alot of items on your van thru this switch. Good luckFord aerostar no fire to plugs.?
To me it sound like a loose connector some were in the ignition system. I would check all of your connectors, fuses and relays for oil dirt oil or corrosion. I had this same problem with my old Toyota and it turned out to be just a corroded fuses that goes to the coil. the car would do every thing you mentioned. by the way Toyota sucks the worst car ever Japanese cars :(. American cars :). any one who disagrees is ant American and obviously knows nothing about cars. Support American cars they are built by hard working people who are dedicated to building quality cars.Ford aerostar no fire to plugs.?
Did a battery light come on? Battery should be around 12v. Could be your ign module or camshaft sensor.
