jdbaker77 Posted June 8, 2014 Share Posted June 8, 2014 I've been looking to purchase a 78 280z and the thing is mint condition with only 40k original miles. The only problem is that he says the z starts up and it will lose fuel pressure and then randomly come back. He says he thinks it's a ground wire but is this worth the risk of buying? What would it need to have that repaired? Quote Link to comment Share on other sites More sharing options...
nops Posted June 17, 2014 Share Posted June 17, 2014 I'm by no means an expert, but maybe there's some debris in the tank that is blocking the suction side of the pump? I test drove a 75 once with this problem and it acted how you described. It may take a while to research and fix the problem, but there's tons of information here and I wouldn't let that stop you from buying the car. Just requires some time and patience.

osirus9 Posted June 21, 2014 Share Posted June 21, 2014 It is most likely rust/debris in the fuel tank. That is a very common issue on these cars. Fixing that requires dropping the tank and either cleaning it or having it cleaned. Then blow air through the fuel lines to clear them out and replace the fuel filter. Not a super expensive problem but pretty time consuming. I suppose it could be a bad pump but most of the time on these cars the pump goes bad because it gets clogged. It is possible that it is an electrical problem too, but much less likely. The electrical systems on these cars are very simplistic though so anybody with a multimeter and the ability to solder can easily repair it.
