I need some advice. I have a D with 7K miles. Original problem is it won't start when it is hot and has set for 1/2 hour or more. I replaced the fuel pump, pump seals, and filter. Now when I start it cold, it idles real slow and will not come up to speed until it has run 4 or 5 minutes. If I press on the gas, it dies. After it is warmed up, it runs fine. If I shut it off hot, it will restart fine unless I let it sit over a half hour, then it will not restart until it completely cools down. Do I need to replace the accumulator? I cleaned the tank and there was very little gunk. Dick Ross Vin 3000
