Question about 1994 Nissan Sentra 4-Door
1994 sentra will crank everytime i try to start it, but sometimes it wont fire unless im giving it gas. sometimes when i pop it in reverse, it sounds as if gas isnt flowing through the system, and the engine shuts off. i still have power from the battery though. ive only replaced the fuel filter, and it ran normal for a day, but the next day the problem persisted. my car is burning through gas, and it smells as if its burning really rich. im not a mechanic, but im very poor and cant afford to take it to one. please help if possible. also, when im driving, the car idles very low, and sometimes the engine will just shut off, whether im driving, or stopped.

Sounds like the fuel pump is failing, have the pressure checked at start up.

SOURCE: car keep shutting down
SOUNDS LIKE THE IDLE AIR VALVE IS CARBONED UP TRY SPRAYING CARBURETOR CLEANER INTO AIR INTAKE AT THE THRUTTLE BODY WHILE HOLDING IDLE SPEED AROUND 1500 TO 1900 RPMS USUALLY AFTER SPRAYING FOR SEVERAL MINUTES ABOUT HALF A CAN THE PROBLEM WILL BE FIXED ...IF THIS DOES NO GOOD YOU MAY HAVE TO TAKE IT TO THE DEALER TO HAVE THE IDLE SPEED REPROGRAMED IN THE ECM WITH THE DEALERS DIAGNOSTIC SCAN TOOL....USUALLY FOR AROUND 50 TO 60 BUCKS HOPE THIS HELPS

I am having the same problem with a Maxima 1995, I have tested each coil for resistance and conductivity, they all seem OK. Just changed the fuel filter. Have cleaned the Mass Air Flow sensor with spray cleaner twice, The screws which hold down the fuel injectors seem to be 'frozen', so I haven't been able to take them off yet. I'm going crazy. I get the gas smell, but I haven't seen any exhaust smoke!
I have been thinking of the fuel pressure regulator, or maybe the fuel pump, but I'd expect the problem to be more constant if these parts were at fault. I can't get anyone to read the Codes for me. The check engine light stays on!

It sounds like the rings are washed out for some reason. any chance you filled up at a gas station with water in there gas ? if it was me I would do a compression test and see if it is low , and it sounds like it might be then leave the plugs out and put oil in each cly turn engine over a few times and let sit over night or at least serveral hours , this will free the rings up , fuel and miss fires will wash the rings out and running will get you white smoke , after oil has set in cyl now you have to clean it out if you have qa air compressor you can shoot air into each keeping a rag over so you dont make a mess, and you can keeping one end in hand send a rag down to soak it up, you will most likely have to pull the plugs out and clean them with break clean a few times till the engine will stay running once it stays running it will smoke until the oil is gone but the compression should be back to normal and cleared up it might smoke for over an hour once you get it running you can hold throttle to 2000 rpm as well this helps a bunch. but find out where compression should be and check it . I think some how either the missfire or bad gas. did you replace any coils or coil pack ? is the miss fire gone?

There is a relay on the rh passenger side kick panel above the automatic transmission module that is controlled by the ECU through the MAF sensor that controls your fuel to the engine so the air / fuel mixture is correct. I fixed a pathfinder one time with a similar stalling problem.

Sounds like you're missing on a cylinder or two. Tune it up, first. That might very well fix your problem. Tell the part store guy you need a COMPLETE tune up kit and replace everything that he gives you parts for. Not just plugs and wires, although they would be better than nothing. I'm pretty sure this will fix you up. The symptoms you're describing are classic for a tune up.
