84 fuel issues?
Hi all. I bought this 84 a month ago and have been tinkering with various things until I was satisfied it was drivable. I drove it home from the previous owners place-ran fine for the 45 minute trip home. Now I start it when it's cold-starts right up. If I let it get up to temp, shut it down and it is a hard start-if it starts. If I turn the key to the on position it do not get a prime spray from the injectors. So today I figure I would run it more than just in the drive. Drove for about 30 mins and it stalls and would not start. I did fill the tank which said half full, but I added 15 gallons. After it would not start and it sat for about 15 minutes I replaced the relay and it started and ran ok, definitely not full power though. Any thoughts? I know I need a new sending unit. And will do a new fuel pump while I am doing it. But is there something else it could be?

If you can get a hose to the very bottom of tank a draw off a sample from the bottom, I have seen a few cases of water in the tank. It gets there usually in inactive cars caused by the drain hose getting clogged and the bib fills with water a leaks in around the cap.
when you do the sending unit/pump hopefully you can do it with a almost empty tank so you can wipe the tank out just in case it's a little nasty. Some tanks look factory clean and the next one could like something Dr. Ballard pulled from the depths

If you are pulling the pickup assembly for any reason, I'd drain the tank to clean it. I'm replacing a defective fuel pump on my 86 and decided while I'm waiting on the new pump to arrive, I'll drain and clean the tank (used on of those Harbor Freight fluid txfr hand pumps}. was surprised at what I got on a rag when I wiped the bottom area. The mower will use up the old gas!

Shoot no. Toss bad gas on a brush fire instead. I can buy 2 stock 84s, mix and match every part on them to put the best of all 3 on my 84 for the cost of my zero turn 
New fuel pump and filter is cheaper on an 84 than the zero too....
