Car starts and runs for 3-5 secs then cuts off
Hello,
I have a 1994 Honda Accord EX 4 cylinder that cranks then shuts off after a few seconds. I've checked the gas and the main fuel relay. The relay appears to be working fine although when I look at it I'm not sure if one of the component connections (see connection port CIRCLED IN RED) is correctly missing. I ran some test on the relay and it seems to check out. I also looked online and couldn't find a similar relay to see what it should look like. Any ideas on this would be helpful?

Does the engine restart immediately?
Suggest turning keyswitch to On and listening carefully for fuel pump in tank to come on for 2-3 secs and go off. This is normal. If you don't hear this sound then starting is unlikely.
It may be necessary to measure fuel pressure to determine if loss of fuel pressure is causing engine to stop. If no loss of fuel pressure, then loss of spark is problem.
Alternatively, you could rig a timing light to monitor spark on one cylinder and see if light keeps flashing (spark) when engine shuts down. If yes, then fuel delivery is problem.
good luck
