1988 Ford Taurus, 3.0 6cyl, 200k

My 1988 taurus has a very strange problem. It always starts right up on cold start and runs excellent. The problem is that after it has been running at full temp and then shut off for about 20 to 25 min. It has trouble starting again. It acts like it wants to start, but dies. If I hold the accelerator all the way to the floor it will start but runs rough for a couple of minutes. If I let the car sit for 40 minutes or so instead of 20 to 25 minutes then it starts fine.

Here is what has been replaced: air charge temp sensor, idle air control valve, engine coolant temp sensor, oxygen sensor, fuel pump, cap and rotor, plugs, purge canister, fuel pressure regulator, fuel filter, and MAF sensor. My local mechanic is at a loss as to the problem. Please help. This is very frustrating, but there has to be an answer.

I should also note that when the problem occurs there is a loud gurgling, grunching sound from the fuel tank.

I know the car has a lot of miles on it, but it doesn't use any oil or blow any smoke, no knocks or noises. Other than the stated problem the car runs great.

Any help will be greatly appreciated.

Thanks, Danny.

You might have solved your own problem, I have been looking at this post for a few minutes and saw the end where you hear gurgling from the tank, I would put a fuel pressure guage on it and tape it to the window (i do this all of the time) so you can see if there is a pressure dropwhen this happens, it almost sounds like the pump is failing, either way check that and let me know what you get

Thanks Jim. I will try that. Even though the pump has been replaced, It has been a little over a year ago, I suppose the pump may be the problem. I am still confused as to why it makes a difference when I let the vehicle cool down for a longer time.

Well not only will this check the pump but all other components in the fuel system that may be suspect, the noise in the tank is what bothers me, I wish I was right there, lmk
