EFI L series engines and other fuel problems

[Richard Clough]

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. --membersozdat------------------------------------------------------- OZDAT Mailing List Please Note:- Send (un)subscribe requests to [EMAIL PROTECTED] Send submissions to [EMAIL PROTECTED] No unauthorised redistribution of this email http://www.ozdat.com/ozdatonline/index.htm http://www.ozdat.com/ozdatonline/listindex.html http://www.mail-archive.com/membersozdat@datascribe.com.au/ ---------------------------------------------------------------------
