these engines are extremely simple, air fuel spark
air: start with compression test
spark: if it seems to run at all then the spark is going, it means the computer is decoding 'cam disc' and 'trying' to throw spark. Pull each plug, crank and watch for spark against intake manifold. verify grounds. If necessary replace ignition components (like a tune up; do a tune up: Cap, plugs, wires, ign module, inspect and clean wiring)
fuel: it goes, maf -> computer -> injectors.
Start with the maf, do a pressure test, play find the air leak. verify fuel pressure. A wideband is infinitely useful here but I do not expect a non performance car to have one. Inspect injector area, injector wires/connections. you can also check continuity of injector wires (unplug ECU and use ecupin ->injector-> ecu pin, so you can see 14-16 ohms on the meter while you wiggle the injector plug if you suspect injector wiring issue.
make sure ecu plug is isn't loose (just snug)
recommendations:
It's usually an air leak or fuel pump. verify fuel pressure and find the air leak.
