HI,

I am sorry that you have not been helped yet. I just came online and saw your question

Has fuel pressure been checked and if so, what is the fuel pressure when it is not starting>

When it wont start, is that occurring only on initial startup of the day when the engine is cold from sitting overnight or does it do it even after being driven and shut off and engine is still warm

Once I get it started it runs fine , when im having trouble starting it and it finally fires up there's a strong smell of fuel ? It doesn't happen every time , it'll start 1st time some days and if I turn it straight off and on but if I pop in a store come out it won't start without quite a few attempts

It gets to about 1000rpm and fades out then when it starts the dial with fly over and back again sounds like I've reved the engine ? I don't know what fuel pressure is just know it runs absolutely fine once I get it started
UK Auto Mechanic: Eric, Automotive Repair Shop Manager replied 11 months ago

Hi,

Ok, by that information, either the fuel pump is losing prime due to drainback or the fuel pressure regulator is leaking internally. A shop needs to check the vacuum hose at the fuel pressure regulator for fuel in it indicating the diaphram is leaking and test for the fuel pressure holding pressure or leaking down and repair as needed based upon both results
