75 fuel injected 1.8. It's happened twice now. Pull into the gas station, fill up, then the car won't start. It will turn over but not catch. Both times, I waited a half hour and then it fired right up. Any common things I can check?
Lots of debates on this one - Read the following threads. I think you will find an answer in one of them. I had the same problem and MY solution was to rip out the 1.8 Djet and replace with a 2.2 6cyl. There is most likely a more inexpensive solution below. Good luck...

If it was my car I would start with the basics, namely, when it doesn't start is it not getting fuel or spark.?
Assuming it is a starter heat issue the six cylinder engines (and starters) have the same glitch. Short of adding a relay I simply got tired of it and installed a high-torque starter... end of problem.
But truth be told the relay is a more elegant solution and saves your ignition switch's (start-position) contacts over time.
Oops. Obviously I just learned how to read yesterday. I stand corrected.
Good luck!
after doing a little reading, maybe the fuel pump or head temp sensor. Head temp sensor is only a few bucks. Thinking about starting there.
Speculating here... could be that the engine is hot, so the head temp sensor is saying, "the engine's all warmed up" but it may need a bit of extra fuel to get it to start. If you can get it to happen again, you might try blipping the throttle while you're cranking to manually add some extra fuel.
Sounds like vapor lock.
Once the fuel stops moving through the system it heats up and the pump wont re-prime.
This is one of the reasons the factory moved the FP to the front and upgraded the fuel lines to handle the pressure.
It also changes the pump from a "puller" to slightly more of a "pusher".

same thing happened on my 75 1.8L. It was the CHT (cylinder head temp) sensor. drove me nuts, but all better once fixed.
Most common problem is the fuel pump ... not the fuel pump itself, but the check valve in it. D-Jet, L-Jet, CIS system are designed to hold 20 or so lbs of fuel pressure in the system for 10 - 20 minutes so the fuel does not boil in the pump. Pump doesn't like pumping vapor.
Hook a fuel pressure gauge into the system and see what happens to the fuel pressure on hot shutdown. If the pressure bleeds off rapidly, it's the check valve that has failed.
