1996 Pontiac Sunfire car will not start

P1601 Serial Comm. Problem With Device 1

Cranks and won't start might wanna do below to find out if its fuel or spark

Get a helper disconnect a sparkplug wire or 2 and ground it to the engine atleast 3/16 away from ground-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,coil's resistances,distributor pick-up coil, ignition control module, cam and crank sensors and computer Note: If it doesn't apply disregard it

we replaced the fuel pump in the gas tank and its getting fuel up to the motor and it has good spark. so it's turning over but when you put the gas peddle all the way to the floor it's back fire's. this anti theft system?? do you hav to have it? we found some wire disconcted or appart.. or can I just take that out and if I do will the car run.
