I have a 91 S-10 with a 2.8 I started to leave for work yesterday and I forgot something inside left it running ran back in the house and when I came back out it was sputtering and cut off. I tried to start it and it acts like it wants to start but will not. I checked to see if it is fireing and it is. the fuel pump and filter is new. any Ideas?
