got her out of the garage after a year parked hand cranked fresh fuel new fuel filter started and run perfectly, changed plugs didn't like that missfire and lumpy idle , changed back to the old plugs now turning over and trying to fire but will not start anybody had the same issues i'm baffled ........

Perhaps put the coil packs back on the wrong way around?

it's something stupid staring me in the face  i'm sure 

 

coil packs breaking down and movement stresses finished couple of them off them off  , visually check them for cracks (fairly common)

Many times I had cop's or coil pack or ht leads failing after r&r doing other jobs and they failing on test run .

customers never understand as they worked before 😕

you could be on to something replaced 2 packs as they were cracked might aswell  change  the other 2 to be safe then check crankshaft and camshaft sensors to see if i've got voltage 🛠️ cheers
