Question about Cars & Trucks
Old, start up fine one out the blue wont start seem to be fuel pump change fuel pump with gm brand 3- times i thought it might be a bad ground
The standard drill is : spark, fuel, timing. Pull a plug wire to test for spark. Give a shot of ether to see if it runs on that.
Cars nowadays don't have much timing anymore, some don't even have distributors. A computer runs it all.
To check the computer, you need a code checker.

have you checked out the core packs? and if you go to autozone you can get a printed diagram where the crankcase sensor is located also look for the location normally under the hood for the fuel pump relay

the enginr oil pressure switch runs the fuel pump till the oil pressure is up to the normal operating range. When the pressure is up the relay kicks in and takes over the power to the pump. The oil pressure switch my be at fault if you can no hear the pump running when you turn the key on
