I had driven my car all day. Was working fine. I went to watch a soccer game on my way home I noticed at first that MJ was really laggy. So at a light when I started up again it was really fighting to move. Next light was uphill, started fine and the drive home gave me no troubles. I stop by a friend’s for no more than 20minutes. I go to start MJ after and starts fine but then drops and dies right away.
Car still cranks and my gas gauge says I have a quarter tank left. And the MAFs is connected.
Any ideas to what it could be?
If there is any detail I haven’t given please ask.
Tyler, I told you. If you think it’s fuel pump, pull plug on fuel filter and
turn ign on or even start the car. If you see constant fuel, might
be something else. I don’t know how else to test the fuel pump (without a
FP gauge) other then what I just mentioned.
Mary Jane. Not a spider-man reference. When I swaped the DE I found a who knows how old small baggy of the green stuff hidden under the center console carpeting. So I named my car Mary Jane.
Yea I went out last night realized I forgot a screwdriver went to bed. Today was all yard duty. And didn’t get the chance.
Did what you said Gautam. After emptying what was in the line put in a bottle and when I turned it on I got no gas coming to the engine. Does this mean for sure garunteed fuel pump problem?
Yeah, where the wires connect to the sending unit typically rust out badly on S13s. Salt gets kicked up onto the top of the tank and rusts everything there.
I know my buddy’s S13 did this for a while, and you could usually get the pump to come back on by wiggling the wires where they come through the trunk floor.
A Carter high flow is waaaay cheaper than stock, outflows Whine-bros, lasts more than a couple months and is a direct replacement. Just a bit of info case you’ve got to swap.
You might have to go in and actually rewire the sending unit to the pump. Depends on how rusty the car is. On the S13 we did this on, Nissan soldered the wires to tabs coming through the top plate, then sealed the connections in rubber. Resoldering them to rusted out metal and rubber is fun. For this you have to remove the pump, obviously.
It sounds to me more like a wiring issue. Fuel pumps usually (in my experience) die slowly, rather than suddenly. When mine went, it ran fine, idled fine, and drove fine, just when I WOTed it, it would start top sputter a bit higher in the RPMs. A few days later, it got worse, happening sooner, but I could still drive it. Then eventually, I could idle it, but any sort of pedal pressure made it try to stall out.
The S13 I was talking about before hand would shut off the fuel pump every time you hit a big enough bump.
