Does not want to restart after a drive

[jlobie]

Hi.. I have a 2000 4.0 Ranger, auto trans, 220K miles. This truck has always ran well, but if I take a short 5 mile drive, stop it and try to restart, it floods and I have to push the accelerator petal to the floor to get it running. When I put it into gear, it stalls. I have to try a few times to get it going. I took it over to my cousins and he put his OBD2 sensor on it and it detected a "low coolant temp" code. So I bought a new engine coolant temp sensor (ECTS) and installed it. There is no difference now. Is there another ECTS on this truck? The one I changed was on top of the intake manifold at the front of the engine. Any thoughts?

99.9% chance of a bad fuel pressure regulator. You can test this by going for a drive, then pull the vacuum hose and watch for fuel to leak out of the regulator.

So it looks like this "fuel injection damper" has a braided line going into the top of it with a crimped connector. How do you change that?

 

[shane96ranger]

The vacuum hose is braided and crimped?

The nipple sticking out of the left top of the damper has a braided stainless steel looking hose with a crimped connector attached to it.

I ordered another damper but did not want to pull the old one off until the new one arrived.

A leaking injector can cause this problem as well as a leaking/ruptured fuel rail damper...

So the question is, what do you do about the crimped connector on the stainless steel braided line going into the top of the fuel injection damper? Can you just pull it off and slip it on to the new damper?

I'm thinking the braided line is a fuel line. It looks like the nipple on the damper with the O ring goes into the manifold and gets its vacuum there. Still waiting to hear what I do about the crimped fitting on the braided line..?

The new fuel damper part arrived today. I am still waiting to hear how I transfer the braided line on top of the damper from the old one to the new one.

I am completely confused about this thread. The pic in post 4 is a fuel pressure regulator. A damper has just two connections. Mine is a simple rubber vacuum line and a nipple that goes into the fuel rail. It is held on by two bolts.

Please post a pic of this braided line. I have looked a two different trucks and the only braided line (metal braiding on the outside of the line) I can find going to the fuel rail is the fuel supple line.

Sorry for the lag. I have 2 vehicles out of service. I started on my Saturn SL1 exhaust and that has been consuming all my time. I will try to get a pic of what has been described to me as a "fuel injection damper" tomorrow. It is just like the one in the pic on this thread. I heard there is a diaphragm in it, and when it ruptures, too much fuel gets into the engine. I pulled my dipstick and it is over full and smells like gasoline. Bummer. I had changed the oil and filter just before this happened! Now I have to change it again after I put the new part on.
