now my 95 boneville wont turn over, it does crank but car wont start? i got fuel, i do hear the pump turn on when i turn the ign switch on, i do have spark, coil packs are good, what else would cause my car not to turn over? my car was running fine until later this day it started running rough i found a vacuum leak and i fixed it and later today when i went to my car now it wont turn over, any ideas or suggestions?

Was the car still running rough after you fixed the vacuum leak ???

Is your SECURITY light on by any chance?

yes the car was still running after i fixed the vacuum leak, and no security light came on

is there any way to check if the ign control module is good or bad? how about the cam and crank sensor is there any way to check those to see if they are good or bad?

i bought a new ign module ( Wells ign module) and the car fired right up with no missfire at all it was running strong, so i thought the problem was solved but it wasn't. about an hour later i went to my car and it wouldn't turn over at all (i just dont get it), so i waited a minute and i tried it again and it did turn over but it was miss firing and surging really bad, iam guessing this is a fuel related problem, yesterday at first when the car was running i check the fuel pressure and i was reading about 42 psi at idle which is good, i check for spark and i have spark, i also checked the resistance on the coils i don't remember the specs but i remember that they were all within the same specs, what should the ohm spec be for a good coil pack? iam guessing its the fuel injectors that giving me the trouble, i checked the resistance of each injector and they were reading about 11.8 ohms, is that a good spec? whats a good ohm spec for a healthy injector? can it be a bad fuel pressure regulator? that may be causing this? my car has 192,000 miles on it and these are the orginal injectors and fuel pressure regulator, also no security light came on, so this is not VATS problem, any suggestions? what do you guys think the problem can be? i mean when i put in the new ign module the car fired right up with no misfiring or surging it ran like new then an hour later the car won't fire up right away and when it did fire up the second time the car was misfiring really bad, i dont get it, its weird, any imput please, thanks

update

this morning i tried firing my car up it wouldn't turn over, so i left and i had to go to work, after i was done with work i decided to buy 3 new ac delco coils and i decided also to buy a ac delco ign module, so after i installed it the car fired right up and seems to be running strong, so i took the car around the block and seems to be fine, ill let the car sit overnight and see if the car will fireup again, i was curious is Well modules garbage? i mean i put one on my car yesterday and it fired right up then after an hour passed by my car wouldn't fire up same thing happened this morning my car wouldn't fire up so i decided to try an ac delco module and new coil packs and my car fired up and seemed to be fine, hopefully this has solved my problem..

A crank or a cam senser will do what your talking about some times it will not start but you go back in like an hour and it fires right up its kinda crazy
cause thats what happend to me Id try to start my car, car won't start, go under hood fiddel around, get back in than it would just start __always had spark and fuel, So I took it to a shop and they said for them to find what the prob was the check eng light would have to be on
It turned out to be a crank senser that craped out on me it starts out nice & slow, every once in awhile it wouldn't start , but as time goes by it gets worse to a point when the car will just die when your driveing . :Not good:
hope your coils take care of the prob. but if it don't than I would guess that it'* the crank or cam senser.

this happened to me also
