Hey everyone,

I have a 1991 CRX HF that is currently in a crank, no start condition. I have some disposable income and wanted to fix it myself so I have more or less been throwing parts at it. So far, I have changed spark plugs and wires, checked fuses, and also replaced the cap and rotor with new ones. There was no change, from there I did switch the main fuel relay for another I had and again, no change. After doing that work I had to go out of town for a couple weeks when I came back I tried to start the car and it fired right up. There were no issues for a couple days so I drove it a few times and eventually as I was driving home going around 30 mph I watched my RPMs start falling while I was stepping on the gas, there was zero throttle response and the car slowed down until it stalled and has not started since. I know all components for spark are how they should be and when testing for fuel after the firewall fuel filter I was reading 10 PSI, this led me to believe it could be the fuel pump and being that it was the original pump I decided to change it. I successfully changed the pump and there is still no change. I can hear the pump priming and I switched my MFR and ruled out one as not priming the pump. I am now completely stumped as this is my first car and I don’t have the most knowledge with cars, if anyone has some ideas of what could be causing this please let me know!!

TLDR: 1991 Honda CRX cranks, no start. Spark has been checked and MFR was changed. Fuel pressure is reading 10 PSI at firewall fuel filter, all work done showed no change
