MG MGB GT V8 Factory Originals Technical - Engine dies - any ideas
|I've just started my V8 after a long restoration, and there's a problem. The motor fires promptly every time but will only run for about a second. It then dies abruptly: it doesn't seem like a fuel problem as there's no spluttering. It runs for the same short period no matter what. It seems like an electrical problem, but I am lost. Has anybody got any ideas?|
|If it only runs for as long as the ingnition switch is in the start position, then the problem could be an open or unwired ballast resistor.|
|I don't have time to work on the car today because of job committments, but this sounds like a sensible answer to my problem. Many thanks George for taking the time to post a reply.|
|To be honest it sounds very much like a fuel problem. My car does that if the fuel pump is disconnected, though it progressively stops starting.. Check your idle mix screws, choke operation etc.|
I am unsure if you have run the motor before or if it is in need of cam run-in, but, once it starts try pumping the throttle a little bit (not over like 2K) I know mine without choke needs a little extra fuel love for a min or two before it will run in it's own..
|I would check out the fuel delivery system. If you unhook the hose to the carb and place it into a container, is fuel coming through? Have you checked the fuel filter for dirt etc. I always like to start with the simple stuff first and work from there.|
|Many thanks guys. One of the things I have done in the rebuild is to fit a 12 way fuse box instead of the standard 4 way. I haven't completed the electrics yet, so I went back and checked the wiring to find that I'd not got power to one of the white wires that should be live when the ignition is on. Hey presto! 2 minutes later and she fired up and sounded as sweet as the day I shut her down 6 years ago. The car is not finished body wise, but the sound through my home-made 2 1/2 inch exhaust is pure heaven. This should give me the incentive to get down to work with the paint as soon as I move house and get her back on the road again.|
