Question about 1993 Pontiac Grand Am
We replaced the fuel pump, crankshaft sensor, coils packs, ignition control module but it still wont start
Once again a first step is to check the main fuses in the engine compartment i had a similar problem with my mazda and learnt a very expensive mistake by not checking this first

SOURCE: car wont start
I noticed you replace the crankshaft sensor, but not the CAMshaft sensor.
The Ignition module takes the input of both sensors to tell the coil when to energize.
This sensor should come up as an error code when you attach a obd reader.
Even if your light is not on - there may be a code. If it is not your vehicle originally, some people pull the bulb!

spark plug gaps are very critical on computerised cars!! [some wont even start!]
distributor module may be breeaking down as temp rises they fail!
otherwise do compression check as it may have valve problems
also check plug leads & injectors aswell as the fuel pump pressure [ could bestarving for fuel]
