i\'ve got a wierd problem
today i took the jeep on a test run up in the hills for about an hour, and she ran pretty good. i got it back, parked it in the driveway, turned it off, went to sweep out the garage for like 5 minutes, went back to the jeep to start it up and pull it in the garage, and she wouldn't fire. she would crank, but not fire.
i could hear the fuel pump turning on with no problem. i looked inside the throttle body, and a light smoke was coming from it. poured a dab of gas in it, and the smoke got a little heavier for a couple seconds...but still would not fire. so i pushed it in the garage, tried again, and nothing, so i let it sit.
4 hours later, i go out in the garage and see if she'll fire, and first try, she starts right up...
any ideas on what the problem might be? this is the first time this has ever happened to the jeep.
lately, the injector has been making noise, and i have plans to change it. but would a bad injector cause a problem like this? should i change the strainer on the fuel pump? one of the sensors maybe? any help is appreciated. thank you
