Location and diagram if crankshaft position sensor

The car doesnt need to run to get a read on fuel pressure just cycle the pump . connect you pressure tester to the schrader valve on the fuel rail .Then cycle the pump by turning the key on but not turning over the engine ,listen for the pump this will prime the fuel rail and you will see what pressure it is making . As the car is a 1996 the obdII system could be of use to you so get the codes read. this will tell you if there is an issue with the crank sensor . As for the location your question was answered by @oldturkey03 here Crank shaft positioning sensor . If the car wont stay running I would doubt its the crank sensor. If it were a crank sensor it wouldn't start at all . I would also look for fuel leaks and check for missing heat shields where the fuel lines pass by anything hot like an exhaust manifold . if the fuel is getting hot in the lines it can vaporize before reaching the injectors
