Re: car will start in park but when you go to drive it it...
This will take two people, While in park have some rev the engine up while the other checks the exhaust flow from the tail pipe. It sounds like you might have a plugged catlytic converter. if its bad you won't notice a sharp exhaust flow diffrence with engine rpm change. Please don't fotget to vote. thanks

are you sure it was the fuel filter the actual problem? may be the fuel pump went out? check to see if you have fuel in the tank some mechanics put some fuel in the fuel filter just like they do with the oild filter.
Replace the fuel filter first, since it is the least costly and user friendly part to get to. My APV had disconnect fitting which you depressed tabs and released the filter from the line. Take the front (engine) side off first. If it is plugged the fuel will not drip on you as much! Good luck. The pump is in the gas tank. You should hear a buzz when you have the key on as it builds up pressure. If not, it may be the fuel relay.
Those rattly noises are detonations, caused by a very lean mixture. All the other symptoms indicate that the fuel flow to the carb is too low. Since you have replaced the pump and the filter, the only other things left to check are the lines and the tank sump. Or you could install a much larger pump.
If the battery is strong and charged, starter is fine, car ran okay while getting progressively worse until it died and won't restart now, might be fuel filter or pump. I've dealt with two cars with fuel filter issues. Both would idle fine, but run progessively worse under load and eventually die and not start although everything else checked out. Engine turned fast enought to start, battery strong, alternator fine, air cleaner clean, all that. No start. Changed fuel filters and done. Everything back to normal. Both cars were about model year 1990 (1989 and 1991). Replaced one in a parking lot and car fired right back up and powered on home just fine, whereas the week leading up to it it ran worse and worse, hesitated on acceleration and finally would die if you hit the gas. Fuel filter may be in engine compartment. Looks like a canister with an in and an out for fuel. Pump is in gas tank and is way more work and money. Good luck, hope this helps.
It sounds (based on your description) like there is a Fuel problem:
1. Check the fuel pressure at the port on the Fuel Rail. Check especially when operating at higher RPM's than at idle or stop. At these levels there is enough gas being provided to keep the engine going. At higher RPM's the Pressure/Volume may not be enough causing the stalling.
2. When was the last time the Fuel Filter was changed? Change this and check operation before moving onto to #3.
3. The Fuel Pump. If the Fuel Pressure and Volume at the Fuel Port is falling at higher RPM's and the Fuel Filter did not help: It sounds like the Fuel Pump is failing. These will fail especially after they warm-up. This problem (losing power and dying) will happen more and more frequently and the Fuel Pump will eventually die all together.
You have to replace the Fuel Filter when you install a new Fuel Pump - it is part of the warranty.
4. The Fuel Injectors: If the Fuel Pressure/Volume at the Fuel Rail is fine, then it is not the Fuel Filter or the Fuel Pump. The problem is "downstream". It may be the electrical aspect of the Fuel Injectors or the mechanical side of the Fuel Injectors themselves. Check each Fuel Injector for correct voltage. If the voltage is correct - Pull and replace that corresponding Fuel Injector. I actually recommend: if you have to replace more that one Fuel Injector - go ahead and replace them all.
It sounds from your description that the fuel pump is weak. To check the fuel pressure you need a fuel pressure test gauge for fuel injection. Attach the gauge to the test port schrader valve and turn the ignition to the on position. Record the reading. Now start the engine and record that reading. Unplug the pressure regulator vacuum line and record the reading.
The pump should have pressure with in specs but if low, start with the installation of a new complete pump. It is located in the fuel tank. Also replace your fuel filter.
Hope this helps you.
Change your fuel filter. Probably clogged. If you get it started, even though it's clogged, the extra work required by the fuel pump to push fuel through will wear out the pump prematurely.
Be prepared to change your fuel pump soon. You probably have two pumps: a boost pump to push it up out of the tank, and a high pressure pump to drive your injectors. So if you change the filter, and you get it running, get ready for a pump change. And while you're doing that, go ahead and change out both pumps. Fuel pumps work together just like your headlamps. If one headlamp goes out, you change both, so do the same with your fuel pumps.
