Engine Mechanical problem
2001 Daewoo Nubira 4 cyl Front Wheel Drive Automatic

Hi guys,

I have several problems my Nubira. It lacks power (struggles over even slight inclines) and also has problems accellerating. It is unable to travel over hills (will shut off). Recently refusing to start at all (battery ok, gas going to filter ok). Engine turns over but vehicle only starts sometimes.Need your help!

Did you have a check engine light come on or has flashed prior to this problem and when was your last tune-up?

Do below to determine whether it's fuel or spark issue:

Cranks but no start condition:

Fuel and Spark:
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.
