my friend has a 1997 crown vic he drove it to the store just fine drove back no missfire no problems at all. turned it off went to drive it latter no start. its getting fuel but no spark, so we replaced the spark plugs and wires still no spark, then we replaced the 2 coil packs started right up. turned it off to go eat came back no spark again. so we replaced the crank and cam sensor still no spark. replaced the relays but didnt replace the diode. what else could it be. could it be a ghost wire some where? any ideas would be great. ooooo and also checked the fuses under the dash all are ok.
