car wont stay running
1993 z24 won't stay running. T started under heavy accelleration. The car would shut off and kick right back on. Then got progressively worse. It shut off for about 20 seconds and turned back on. Drove it home and hasn't started since. I changed the fuel pump, relay, filter, injectors, coil packs, ignition module, plugs, wires, and crakshaft posistion sensor. It starts, runs for 1-3 seconds and shuts off. Need help asap. Only means of transportation and I nee the car for work. Thank you
