Driving on interstate and car motor went dead.
I had just had two belts changed the belts broke and we continued to drive with belts slapping around under the hood. They were hard to untangle from the pulleys.

Mechanic tries fuel pump and all relays.
says that one side of the pump gets juice but other
going into another part does not. He is saying New Computer that cost 12 to 1300.

What is the next step. Hasn't been running for three weeks.

Thanks.

Hi Thomas427, Welcome to 2carpros and TY for the donation.

Do below and find out what's missing between fuel and spark and then comeback with results

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, Do you hear the fuel pump come On when you turn key on? If not check fuel pump fuse and fuel pump relay if so, 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, cap and rotor, distributor pick-up coil, ignition control module, cam and crank sensors and computer Note: If it doesn't apply disregard it and keep testing
