Q: My truck starts and shuts right off

asked by on

cant keep my truck started

My car has 12000 miles.
My car has an automatic transmission.

This may be related to many different possibilities, however since the truck will start even for a minute, this suggests it is likely not related to an issue of producing spark. In the case of a fuel delivery problem, this may be related to low fuel pressure, faulty or dirty fuel injectors, a faulty or dirty idle air control valve (this relays information about air intake to the computer which makes fuel adjustments), or potentially a faulty fuel pressure regulator or fuel pump. Fuel delivery problems will typically not allow the proper amount of fuel to be delivered to the cylinders which results in a lean fuel condition which can cause backfiring or simply cause the motor not to stay running as a result of fuel starvation. I would recommend having an expert from YourMechanic come to your location to diagnose and inspect your vehicle.
