Just had the fuel relay replaced on my 91 dx for a problem I'm assuming wasn't related, and something new's come up. It died on my way to my girlfriend's house yesterday, and I was able to start it back up for a few more blocks before it happened again, but now when I turn the car over it won't stay running. It fires, and will rev for maybe a second max if I hit it, but then instantly dies out. I believe my timing belt is loose, could this problem be caused by that? Also: For a car I spent $300 on, but have put probably $1000+ into just to keep it on the road, is it time for me to cut my losses? I just spent $250 on tires, etc. a few hours before this happened, and haven't paid off the fuel relay yet... Suggestions or advice would be greatly appreciated; The car is stranded in my girlfriend's yard 50 miles away.
