It cranks for an extended time before starting. There are no codes and it runs fine once it has started. It has 60,000 miles. I have not connected a fuel pressure gauge, I assume it is either a fuel pump or pressure regulator. Hammer Time Ultimate Carjunky / Moderator Oct 25, 2009, 4:33 PM Post #2 of 3 (1313 views) Re: extended crank before starting Sign In Your on the right track. It could be a bad check valve in the pump allowing the fuel to siphon back into the tank or possibly a lazy relay not energizing right away. You need to hook up a fuel pressure gauge before attempting to start it so you can see what the pressure does. ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ We offer help in answering questions, clarifying things or giving advice but we are not a substitute for an on-site inspection by a professional.

I am used to the Schrader type valve used on the domestics. I will hook the gauge up once I find an adapter. I was just wondering if there has been a common fault like the pump check valve.   Automotive Repair     Auto Body Repair and Refinishing     Heating or AC Issues     Electrical and Wiring     Brake Systems     Car Stereo Repair Advice     General Discussions     Car Making Funny Noises     Engine Fault Codes     Engine Troubles     Exhaust Systems     Steering and Suspension     Transmission Troubles     Tricks of the Trade Automotive World     General Discussions     Antique Car Talk     Car Shows and Events     The Bargin Bin     Motor Vehicle Inspection     Car Care Tips     Traffic Tickets     Gasoline, Motor Oils, Concept Cars and Engines     Auto Insurance, Financing, Leases, Warranties Truck Repair     General Discussions     Truck Engine Repair     Truck Suspension Repair Motorcycle Repair     General Discussions     Motorcycle Engine Repair CarJunky     Open Posting     Board FAQ's     New Board Suggestions
