Re: New user need some help
I would first check all your vaccuum hoses, especially the vaccuum advance hose that connects to the distributor. They get crumbly after a while and can cause leak problems.
Does this problem occur right after you shift into fifth gear? There is a switch on the transmission that connects to the Electronic Control Unit (ECU) which controls the carburetor. If that is the case, maybe the switch (or the ECU) is bad...
About the fuel pump...
Although checking the fuel pump is always a good idea, I don't think this is the problem.
To check the fuel pump, locate it on the rear end of the head on the passenger side. There are a number of tubes coming out of it. One points down and has no hose connected to it. This tube provides an air vent to the backside of the pump diaphram. If the diaphram is ruptured, this tube will be damp with gasoline after you run the engine for a while.
Another indication of a broken fuel pump is progressivly louder engine noises as it is driven at any speed. This is caused by the thinning of the oil with gasoline from the pump. Naturally, oil thinned out by gasoline is a VERY BAD thing.
The final indication of a broken fuel pump is found when you check the oil level. The oil will be noticably thinner and there will appear to be more of it!
