Crank no fire, you hear the fuelpump come on, Id start by checking spark if you have no spark, could be a bad coil?, maybe bad cap and rotor Kindo doubt if this happened all of a sudden? but maybe, possibly a bad pickup module in the distributor.. make sure the rotor is spinning on crank and the thing dont have a busted timing chain or gear or sheared rollpin in the distributor. finally if all that checks ok, hmm well maybe check and see if its got injector pulse? Possibly a bad driver in the cpu or something allong these lines <---usally not the problem but it is possible.
hope these sudjestions help
