my truck revs up the rpm then dies when I crank
I have a 97 chevy c1500 5.0 and when I crank it the
rpm goes really high then it dies. I have changed
the fuel pump and throttle positioning sensor and
idol control sensor but it still didn't fix it.
Sounds like there is a vacuum leak somewhere. Check for cracked vacuum lines, check the throttle body gasket, & snug up the intake manifold bolts.
Ok where would the vacuum lines be. I know that sounds dumb but im not a mechanic
They run all over the top of the engine.
