i have a 95 sho 3.2l the car starts up in the morning,sometimes it runs fine then sometimes it runs and then cuts out.sometimes it drives fine and sometimes it drives and then cuts out.i have to let it sit for a while before it starts back up.from reviewing the forum i decided to change the crank sensor.before changing the crank sensor i could always hear the fuel pump prime with the ignition turned.i replaced the crank sensor following all procedures and tried to start the car and no start.when turning the ignition i noticed that the fuel pump was no longer working.i checked the wires going to the inertia switch and i got no power.i also tried to run the self diagnostic test and it wouldnt work. the fan wouldnt start during the test,either.all other power is working,the car cranks fine but wont start.i backprobed and ran a test light to the crank and cam sensors,the ignition module,and the coil and i got no power.is it the relay box above the radiator or what? i also checked all fuses.

unhook the battary cables to reset the ECU, and clean up the connection while you are there. if that doesnt help, then look over everything you touched while changing out the sensor(s), usually the ground on the passenger upper intake manifold is forgotten, but if your fuelpump and some other things are not working, you may be in for more work.

fixed the car,10 amp fuse in the main fuse box under the hood, driver side, next to firewall.the fuse is marked accesory.got info from one of the treads on forum.this fuse controls the ircm relays output.if its blown your cooling fan wont work,your fuel pump wont prime,you cant run the self diagnostics,and possibly something to do with your ac.would never had thought a fuse marked accesory would control such sensitive parts that would prevent your car from starting.check that fuse before any diagnostics. thanks forum members
