won't restart
 

rebuilt tranny and now can't get truck to start. turns over. fast at first but quickly slows. new battery. truck was running fine when
parked.. a relay or fuse popped i think. something popped. fuel pressure ok. have fire at #1 plug. starter did sit
outside in a plastic tray under truck while i did tranny. not in direct rain tho. thinking possibly brushes. help! :)

update! motor is turning backwards when trying to start. what in the.....? again, was starting and running ok when parked.

Year, Make, Model, Engine?

Check the polarity of your new battery.
