I got a 94 LS with 171K. I was drivin down the road then suddently my car sputters and dies on me. Wont restart. I checked everything i could with the tools i have. Fluids, timing belt, plugs, wires, cap. just the usual stuff. Could it be my fuel pump? when i switch the key to on i can hear something humming under the hood. the car just cranks but will not fire up. The Maintenance Req. light is flashing but i dont know wut for. I really need my car back on the road ASAP but i need some help, any suggestions would be really helpful.
