Subject: EFI L series engines and other
fuel problems
Luke Clough has been have little joy in his
1600 since installing a VL Commodore fuel pump to his EFI L series engine last
week. His idea was to overcome fuel starvation being
experienced on very hot days after sitting at the lights, by pumping more
fuel to cool the rail.
Problem became even more pronounced this week
leading to embarrassments like pushing the car after it dies at the
lights!
I travelled to Melbourne today tandem
trailer in tow and I was under
instruction by my financial advisor (wife, Lynn) to hand over her
Commodore to Luke, so he had reliable transport for work until he,
or I, had his fuel problem sorted out.
I have been nagging him to replace the
original fuel pressure regulator ever since he fitted the engine, as its
adjustment thread was worn out. Obviously motivated by the threat of
driving the Commodore, Luke finally did it
today. The replacement regulator cost $4 (off a 6 cyl EFI Skyline). So far, his engine is
purring and pulling strongly at 5500 - something it didn't do before-
hopefully problem solved.
I'm not saying anything.
Meanwhile his sister Amy's Mazda
Capella (piston engine) has been reluctant to start when
cold. It pops and spits back as if it has a manifold leak, or is
running lean. But as soon as it gets a tiny bit of heat in the
engine it runs like a watch. I have swapped carbies, fitted a new
coil, leads and points, checked for leaks in the manifold. No
change.
Any Suggestions anyone?
I had to smile as I was coming home from
Melbourne tonight still towing the tandem, with the Mazda leering at
me in the rear view mirror. I was supposed to be bringing the Datto home
to fix, but a simple $4 part got it going well. However, $64
didn't fix the Mazda - typical. I wish we had another 1600 for
Amy.
