It starts really rough, and will suddenly die until it warms up. It seems like its not getting enough fuel to the engine. When driving I can barely get to 30mph. and if you put the pedal to the floor it just dies. The only way I can drive it right now is to lightly feather the gas pedal and slowly get up to speed.
Here is a little back story with my fuel pump.
I have had the fuel pump replaced 3 times by a local mechanic. The first pump was defective from the manufacturer and the mechanic had to change it right away before I picked up the car. After he it the second time, I drove it for about 2 weeks and then it just died in a parking lot. Couldn't get it started at all. Banged on the gas tank and then she started right up. MY mechanic changed the fuel pump once again, (this is the third one!) and it everything.
It has been about 1 month since my last visit to the mechanic. I recently ran right out of gas, (My instrument cluster works sometimes, and was lying to me about how much gas I had) and since then, I have been dealing with this extremely sluggish driving, almost like there is no gas going to the engine.
Could this be simply due to a clogged or dirty fuel filter?
Checking my trouble codes, I received a CODE 42:
Fuel pump relay control ckt, Auto shutdown relay control ckt, No ASD relay output voltage at PCM, Fuel level sending unit volts out of range.
and CODE 51:
Fuel system lean ( this code came up when I ran out of gas)
Its a 1996 Dodge neon SOHC, with a plastic gas tank.
Any help at all would be greatly appreciated. I know this car is on its way out, but aside from this fuel delivery problem she runs great, and I can't afford another one yet.
Thank you in advance

Before spending a lot of bucks, buy a bottle or two of HEET, Water Out,Dry Gas and drop in the tank, the issue may be a simple as condensation or water in the fuel. The conditinos you describe surging, inability to accelerate cutting out are also symptoms of water in the fuel, give the dry gas products a shot they are cheap.
Thank you vabear, I appreciate your input. I will give that product a try!
To update: I put in a new fuel filter this evening, and I am still having this issue. But I noticed a different sound when I was under the car. When you cycle the ignition on and off you can hear the pump build up the pressure in the system,(which is normal) When I turn the key back off I hear a gurgling and bubbling sound coming from the gas tank. Is this due to a leak in the fuel line ? Its my next fix that I am thinking about.
Thank you for all of your help,
Thank you for the replies, I appreciate your professional advice.
The first 3 pumps were not OEM. I am towing the car to my mechanic today and Will be installing an OEM Bosch Fuel Pump. That comes with a 1 year unlimited KM warranty. Hopefully this will be a permanent fix.
My Mechanic thinks that there is something electronically wrong with my car that is frying my Fuel pump. He thinks that either in the relays or wiring harness the amount of voltage that is going to the pump may be too low and that is causing it to heat up and fail prematurely. Is this possible? If so, how can I fix my wiring issue?
Wasn't there an issue with the upsteam O2 sensor wires getting a short from being constantly rubbed and when it bumps into something, it shorts out the fuel pump? I seem to recall that being on one of the threads at one time....
Just checked. The fuel pump fuse blows. So unless that is something else that is happening, that is most likely not your problem.
