Hello. New to the forum. 95 GT 5.0L, 5 spd. Runs perfectly when running. Car starts well. Next time, crank but no start. This goes on time and time again making the car unreliable to use as you never know when it will happen or where.Might run for a week, a day, an hour without this happening again. When it does this, may start after an hour or less sitting or it may not but it eventually starts. At my wits end as are the mechanics. New fuel pump, distributor. Local mechanics cannot isolate the prob it seems. Thought someone here may be able to help. Not a mechanic with limited mechanical knowledge. Mechanic says every thing checked including codes, injectors ,spark. All seems fine. Thanks for any help.
