Q: Won't fire

asked by on

My olds just stopped running on interstate. Got it home fires on starting fluid so thought fuel pump but after unhooking filter tried it worked fine . So I'm thinking it must be in the injection system

My car has 174000 miles.
My car has an automatic transmission.

The vehicle uses the crankshaft and camshaft sensors to control the spark and fuel injection of the engine. You should have the computer scanned to get codes, to see which sensor set a code.
