Posted on May 04, 2009 One of the items you can try is to turn on the ignition switch, so the dash board lights come on, and wait 10 seconds before you start the engine. Have you checked the fuel filter to see if it is clogged? I don't know what relays and fuses you want to check, but your 1988 Nissan Sentra is equipped with a mechanical fuel pump which is located on the rear of the engine under the intake manifold. Then noticed the fuel pump would not run. And so, there's no need to spend time testing them or money replacing them. Most of the doors had a small plastic cap which you pry up and below that cap is a screw which you remove with a 6 phillips screw driver that is the most common size phillips used Once the screw is out, move to the front of the arm rest and pry it up like you did the back one. I checked the three blue relays next to the fuse box under the dash thinking one of them was the fule pump relay. The power antenna timer is a larger box near those two relays according to that diagram.
As are the diagrams of the fuel pump relay location, the procedure for checking the fuel pump relay are also splattered about. So the more details the better. You need a small flat faced screw driver and get a piece of cardboard which you can slip between the screw driver and the panel where ever you might pry against so you don't cut it or mark it. Since the car had 231,000 miles on it, I opted to put in a new, used engine. This time we conveniently broke down in front of an auto repair shop so we asked the mechanic to look at it the next day. The absolute best way to test the fuel pump is with a fuel pressure gauge. The pump was not coming on, so I checked the moduled.
It takes 15 minutes and about 20 tries to get the car going now. If I turn the car off for longer than 15 minutes, the problem comes back. Would cracking but no start. No Start 1: Checking For Spark The starting point, for any Cranks but Does Not Start condition should be testing the ignition system first. The next morning when I went to leave work, the directionals worked fine again. The fuel from the fuel pump goes to the fuel rail that supplies fuel to the fuel injectors.
You have an electric fuel pump and it must build up pressure so you have the correct volume of fuel going to the fuel injectors. The extra ground wire is a fairly common practice. Push the lever down while rocking the connector side to side a little while you pull on it. The engine turns over and starts right up, then immediately dies as if starving for gas. Your vehicle is also carbureted, not fuel-injected, so If I had your vehicle and it was lugging out on take-off, I would be looking at the accelerator pump in the carburetor, not the fuel pump.
I'm just looking to get some of my money back. Disconnect fuel tubes and connector, then remove fuel gauge assembly. Your next step is to verify fuel pressure. There are two screws which fasten the door panel to the door around the area where the arm rests were, They too are phillips head screws. Pull up the front of the chamber.
Tried pulling a fuel line at filter, didn't hear pump, no fuel came out when turned on. The car would start with aid of starting fluid. I also had starting problem on my 01 sentra 1. If you could, your relay is probably be okay. Anything you can offer will be helpful.
Thank you very much from a stumped nissan owner :o Electrical problem 1992 Nissan Sentra 4 cyl Front Wheel Drive Automatic Having Issues With My Nissan For Like 4 Days Now, It Wasnt Starting When I Tried To Run An Errand One Night, So I Tore The Car Apart With A Couple Friends, And Came To The Conclusion That The Problem Lies In My Fuel Pump Relay --Bought A New One From Napa, Not Sure Why But It Just Wasnt Right When I Plugged It In, So My Brother In Law Pulled A Radio-shack Toggle Switch hed used for his stereo Out Of His Truck And Rigged It Up To Fit my relay Relay And Solve The Problem! Is there another way, or do I have to disassemble the entire dash area and take loose the steering support to get this relay? The mechanic changed out the coil and it ran incidental? But I will check out the pump closer now. After about 15 minutes of trying over and over again, the car will maintain rpm's and run fine. If so, What Do I Do? The excess fuel is then returned to the gas tank. It was determined it needed new fuel pump. I'd say your low idle issue is related to a dirty intake and throttle body. I may have a bad check valve which then allows the gas to drain from the fuel rail, but I have not gotten this far yet in my own repair.
Fuel pump control unit seems to operate fine. Still, the other method that I've used to test for a lack of fuel. From the reply to your post I now know that the relay is in the trunk, and not one of the three blue ones next to the fuse box under the dash. If the temperature falls below 60 degrees during the night, when I go to start the car up in the morning, she starts right up, but shuts right off. We had the car towed home where he tried jiggling some wires to see if that was the issue. A few miles, quit again. Really need the Consult to gather data on sensors.
