crazy fuel pump prob 82 brat

My grandpa thought maybe something along the lines of the auto choke trying to shut off the fuel, or some other mechanism doing so??
Thanks, Tim I

I would purchase a service manual for your car so you will have a reference to go too when things like this happen. It can save you a lot of money in the long run.

My 82 Hatch had an intermittant fuel pump problem too. It would just leave me stranded and then it would fix itself. I took it to Nate Wade Subaru and they attached a light bulb to test/diagnose the fuel pump system and were able to determine that I had an intermittant short.
Replaced the pump and never had a problem since.
I have a Trooper that ate SIX fuel pumps in TEN months! (Dealer paid for most of them) They finally figured out that the wires were corroded and causing a low volatage to the pump causing it to burn out. Are your wires corroded?
82 Hatch, transforming.....:temper:

An 82 Brat can have an ECU/Computer. If you have an oxygen sensor you have an ECU. Its bolted to the bottom of the steering column in the area above your shinbones/knees when you are sitting in the brat. 1bbl carter weber carb models had the ECU. I have an ECU from one in my basement.
I think check/clean all ground wires is a great suggestion that was noted above. Its also a 20+ year old component so if you can find a good price on one-replacement wouldn't hurt.

You can use a voltmeter to measure the switched leads. When the relay is engaged, the meter should show zero volts (a shorted condition) between the two switched leads. If you show a voltage then there is a resistance between the leads causing the voltage drop and you need to replace the relay. You will need to catch this when the problem is happening to prove out the relay because relay contacts can be intermitant just like the problem you are having. You could just try replacing or swapping it to see if that will stop the problem. It is much cheaper and easier to replace the relay than the pump. I would want to prove it is the pump first before replacing it if this were my car. Pumps are a common problem also though.
