I got the car from a co worker. After 1st start of day car will not start without giving it gas rest of day. Shop told me alternator was draining battery and a new crankshift sensor was necessary. Agreed to new battery, alternator, crankshaft sensor. Now shop said computer burnt out and they need more time, it has already been a week. Any ideas?

What do you mean by this-is giving it gas thru the throttle body or stepping the gas pedal to get it to start?

Do you hear the fuel pump come On? If so check the fuel pressure to rule the fuel pump and check the engine coolant temperature sensor

I hear the fuel pump come on. The shop seems to think it is a electrical/wiring problem. But it does seem odd that it will start right up after sitting all night. But after sitting for 8 hours it will give problems. It always starts however, or it used to.

Get the fuel pressure checked out fuel pump could be failing, The best way to catch this when it refuses to start is do below it will tell you if its a fuel or spark problem

Get a carb cleaner and spray into the carb or the throttle body on an EFI. Did it start and die? If not disconnect a sparkplug wire or 2 and ground it to the engine -have helper crank engine over-do you have a snapping blue spark? If so-you have a fuel related problem, check the fuel pressure to rule out the fuel filter/fuel pump/pressure regulator and listen to the injector/s are they pulsing or hook up a noid light. No snapping blue spark continue to troubleshoot the ignition system-power input to the coil/coil packs, distributor pick-up coil, ignition control module, cam and crank sensors- Note: If it doesn't apply disregard it
