The check engine light comes on if a malfunction with the emission control system has been detected - it can stay on - or may go out and come back on in the future
If the check engine light is flashing with the engine running , that means a spark plug misfire has been detected
If you have an automatic transmission, check with the engine warm and running, The dip stick is located on the passenger side rear of the engine.
your fuel pump could have quit, but if the truck was running when it happened its unlikely. you may have a clogged fuel line or filter. an if the engine doesnt turn over at all then check your oil. if you got an oil leak an didnt know it you may have seized the engine.
the service engine light is on due to the fact that there is a problem with your truck, this is confirmed by the way your truck is running. you need to get a engine diagnostic check at an auto shop. may just need a tune-up, or the truck has a bad sensor, or engine woes.
Check the proportioning valve.
engine needs 2 b running at the right hand side of the truck at back pull out dipstick read it
NO. That means the engine is running too hot. Check cooling system.
you need to be more specific... what kinda leak is it?? most likely engine oil or transmission oil, check on your dipstick and make sure the engine is at proper level, to check the transmission you have to crawl under the truck and remove a plug on the side of it. also how is the truck running rough??
That depends entirely on the reason why the check engine light is on.
Engine is running rich
No you can not , That is what makes and keeps the engine running
