1998 sunfire gt 2.4liter

I have a 98 sunfire with a 2.4 motor.I bought the car with a blown engine and have put in a 2.4 motor again,when i go to start it with the key turned ahead
i have no waring lights on the dash & the fuel gauge does not work.The car will start and 2 sec shut off.From what i have been reading it sounds like it may be the theft system,but i don't have any lights on the dash working.Any help would be great:frown:

Check all fuses and look for any wires disconnected.

Have done all those steps and still same problem.

Fuel pump man I have a 98 SF 2.2 have replaced the fuel Pump 3 times for the same problems. :)
