check the coil pack...use a screwdriver in the spark plug socket near ground...look for a spark....test the ground and hot connections to the coil pack...suspect there is a problem with the spark...might be as simple as cleaning the grounds with a wirebrush~

I had removed all plugs and have very good spark. The car died on me one day let the car sit over night and it started that am enough for me to pull it the ramps and has not started since

the motor locked up? or bad gas or choked filter? feel bad if the motor will not turn anymore...had cases where a chap (my friend) bought another starter...only to discover a completely locked-up engine.....so my advise is see if you are able to turn the motor...either with a big socket on the crank pulley...or by putting it in gear and pushing (if manual)~ so good luck~

No it cranks great has great spark and good fuel pressure have not checked compression but you hold your finger over the plug hole it just seems like there is something not giving the injectors permissive to open

align the crank to TDC...check the positions of the crank...perhaps you've jumped a tooth~ or timing gear belt or chain needs replacement~
