I have a 1989 2.6. If it gets up to temp and then I shut it off it won't crank up for about an hour. I have replaced fuel pumps, filter and accumulator. In addition when it is running and in gear the idle is rough at times. If I idle in gear with the A/C running it almost dies. Any ideas would be appreciated. I read a lot of posts and that is what lead me to the accumulator but I changed it out and no change.
