I started my Bronco (1990, 351) early the past morning and it fired right up, ran for about 10 seconds and died. It wouldn't restart at all after that. drove another truck to work, searched the website here for all the code info to see if I could try and fix it when I got home. I did the KOEO test to pull the codes (since it wouldn't start) and the check engine light came on and stayed steady for about 3-4 minutes. No code blinks. I could hear switches cycling under the hood so I think it was testing. I tried resetting the test wire to make sure I had a good connection and got the same results. Any ideas or suggestions ? If it would run I would take it to my local shop but it wont even start. Thanks
