wont start

alright i have a 95 E150 van with the 5.0 int it. yesterday i put in some subwoofers and so i had to disconnect the battery. the van ran good before but when i connected the battery back up and tried to start it, it wouldnt start. all it does now is is crank over and over. it has to be something with not getting spark or gas but im not sure. anyone have any ideas???

You didn't break/disconnect small wire on the starter relay ,did you?

Check all the fuses to make sure you didn't blow one when disconnecting and reconnecting the battery.

Do you find you problem? I have almost the same thing happening to a 93 5.8L Battery was dead for about 6 months Charged it & now I have no spark. Was running great before it was parked.

If it has a distributor use a 12volt test light and check for voltage to the coil positive when trying to start. The put the connection on the coil negative it should flash if somebody is trying to start the vehicle. If it flashes take the module to Advance or Auto Zone and get it checked. If it doesn't flash replace the pickup in the distributor.
If it has a camshaft position sensor unplug it and use and ohm meter across the two terminals. It should go from zero to one if its good. Be very careful you don't get caught in the belt. You might have to remove the belt to check or make temp leads.
