An exhaust leak on the front right side of the engine where there is a rubber connector burned insulation on wires and two vaccum lines. I taped up wires and repaired vaccum lines. The vehicle will start and stops about two seconds later. I have checked all fuses What is my problem?

Could be fuel or spark problem-Do below

Get a helper disconnect a sparkplug wire or 2 and ground it to the engine at least 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
