    P38A 4.6 cranks, sparks and coughs but won't run - Fuel pressure?

    Hi Oakley, still getting used to this forum. It has some strange quirks. Seems you have to press the post reply button twice. First time is kind of view draft function I was not expecting (might just be my laptop or big fingers!). Maybe next time you are up. Starting seems to be intermittent now...

    P38A 4.6 cranks, sparks and coughs but won't run - Fuel pressure?

    It runs, sweet as a nut. Hot wired the fuel pump and ran a gallon of fresh fuel through, good fuel pressure when cranking but no check valve. Pressure drops off immediately.

    Oakley, That would be great. I am out by Inverurie. Send me an PM. I plan to be working on it Monday evening but will also be at the workshop or nearby Monday afternoon. I will also see if I can lay my hands on a fuel pressure gauge. Any details on shorting the pins on the relay to make the...

    P38A 4.6 cranks, sparks and coughs but won't run - Fuel pressure?

    Hi Alan, Put new fuel in the tank and pump is working on position II and sends a good burst of fuel through for about 3 seconds. So the pump is working. I think the problem is that this initial pressure is either not being maintained or the pump is not running while cranking to maintain...

    Hi, I am a newby to Range Rovers and have taken on a project to build a light weight tube frame rear engine buggy using P38 mechanicals. Been helping a mate race a RR classic based Bowler and quite liked the rear engine buggies racing in the comp safari's. Donor car is a 1995 P38A with Gemms...
