Question type: Maintenance & Repair

2 Answers

have you looked at your fuel pressure regulator at all, it is a diaphragm with a vacuum connection to it, on or just before the fuel rail...perhaps this is disconnected and givin' too much pressure....those butyl rubber vacuum hoses are cracky and leaky too~ replace with silicone vacuum lines~


Did you replace the fuel filter and FP relay also? Check the low oil pressure switch and check the inertia switch both of them can really give you a headache.
