Clean the entire throttlebody all the sensors but a new crankshaft position sensor won’t start but when it does start it won’t even idle for about 10 seconds before it dies have fuel pressure but then loses fuel pressureHas hesitation starting and to stay running won’t idle for more than five seconds but if I give it gas it automatically kills it
