I have an 89 wrangler YJ TBI with 2.5 liter 4 cylinder that is hard to start when it’s cold. It will fire rather quickly but immediately dies. Sometimes it takes 15 or 20 tries to keep it running. Once it warms up, it runs well. I noticed the electric fuel pump stays running almost constantly when the key is turned to the run position. Should it only run for a few seconds until it pressures up and then kick off? Any suggestions would be appreciated.
