Are there any error codes in the computer? (Do you know how to check?)
Are you sure it is a fuel system problem? Or could it be something else stopping working? (i.e. do you watch the fuel pressure drop off?)

This is my first post so, thanks in advanced to all who take there time to view it.
Car-
1992 Buick Regal Limited
3800, Automatic Trans, SFI Injection
Replaced Items-
Intake Manifold Gaskets-Fuel Pressure Regulator-Timing Chain-Interuper for timing sensor located in timing sprocket (dealer item only)-Crankshaft Sensor-Fuel Filter an plugs and wires
Checked and/or cleaned-
Idle Air Control-Coil Pack-Fuel Pressure ( 46-48 psi, cold) -Fuel Pump Relay-Fuel Injectors
With this all done I still face the same problem.
At first the car would not start if it were run for awhile and shut off. When you let it cool down it would start and run fine. Now it has started stalling out while driving and will not re-start until cold but it's still a bear to get started.
The idle is rough and as it warms up it wants to die out again, the only way to keep it running is to give it more fuel.
When it dies while driving it's like running out of gas, there is no strange noises just a total shut down like turning off the key.
Any ideas?? I've done alot of work to this car in hopes of fixing this
Well.....I just pulled the injectors to find a milky substance on the #4. Removed the plug and cranked it over to find a shower of chocolate milk looking stuff on the firewall
What do you all think, intake or head??

Bobc455-
Thanks for your reply and there were no codes before it died. The last code was the cam shaft pos. sensor but, that along with the timing chain was replaced. As for the fuel pressure...
it's at 48 psi (not running) and 46 while the engine was at a idle.
I have found that one of the injectors are cracked and the antifreeze within the #4 does not mean good times are ahead.
I think the combo of the blown intake (making a vac. and water leak) along with the cracked injector might be my problem.
BUT...I am not a Pro and this would be the reason for my post.
If anyone has other ideas please reply.
