Ok about a year ago turned the key and engine would crank but no start 30 mins later started ran fine off and on over year would get same. Engine turns over but no start. Got a spark tester and confirmed no spark after few seconds of crank got spark and engine started. 149000 miles new plugs and coil pack all 8 at 102000. Engine runs great not a fuel issues positive looked at crank sensors on cam area and on lower end near a/c and all wires and plugs look good. Problem normally no start happens away from home and tools so can't check the sensor wires for voltages starts up and may not happen again for a week or 4 weeks. So very hard to diagnose. No codes when I hook my cheap reader up. Complete loss any help.
