Please help if you can. It will start up first thing most every morning and run fine, doesn't die on me while running. but after it runs for 15 minutes or more and i stop it won't start again, sometimes not for a few days or more. The book says it is K-Jetronic fuel injection ( the CIS type) and i have listened for the whirring sound in the tank that tells me the pump is working. The book indicates the issue is leaking fuel pressure, but i see no indication of leaks and typically when i chcek at the filter there is fuel present. Anyone out there run into this problem? I am having trouble identifing all the components uner the hood i.e. (Fuel pressure regulator,system pressure regulator, auxillary air regulator and mixure control unit) all of which are on the list of things the haynes manual says i should check. I can't afford to shotgun troubleshoot and replace each part even if i could find the parts outside of a junkyard.
