i got off work one night an went to install a radio in my 95 DX an while i was installing it i crunk the car up an turned it off twice an once i was done with the radio i went to start the car an i got nothing it just wouldn't start iv replaced the dizzy,main relay,fuel pump,ECU, and the ignition an it still wont crank dose any one know any thing elts i can try??? please help

well dose the motor crank over and wont start or just nothing

if just nothing

you may have a lose starter wire or a bad starter
a dead short in the wiring
a bad battory
a bad fuse

if it we'll crank over but not start

try truning off every thang and truning the key lison for the fuil pump to kick in if not maybe a bad fuil pump
try taking off a spark plug wire put a scruw driver next to the wire end and have a friend crank it over if nothing it could be a bad dist. a bad dist. cap or a bad dist. roter butten

iv done all that the fuel pump dosnt prime but its good when str8 wiered

sounds like the (fuel pump relay)

its a little box under the driver side dash that turns on the pump wen you turn the key

Does sound like the main relay : http://www.tegger.com/hondafaq/mainrelay.html
If not the main relay, we used to wire some of our units to the ignition, check the fuse box under the hood and make sure they are good, and this happened while putting in a head unit. did u move or cut any ground wires if its not the main relay or a fuse then pull your unit and make sure all your grounds are on metal and connected, use wire brush to clean the surface before bolting grounds down, may as well check grounds at thermo housing just for the hell of it, never hurts.
