Nissan Repair: 1994 Nissan Sentra LE, nissan sentra, vacuum hose

Question
Hi Calvin,

I have a 1994 Nissan Sentra with the 1.6 liter engine.
Lately it has developed an annoying problem.



Sometimes I can drive it for days on end with no problems.
The next day it may run fine for a few miles and just shut off and not start again, but it'll almost start if I hold the gas pedal on the floor.

If I let it sit for about 30 minutes or longer, it'll start right up and run perfectly, maybe for days, maybe for a few minutes.

I've changed the fuel filter, and cleaned the fuel system out with Seafoam.
It has new plugs, wires, dist cap and rotor, new fuel pump and fuel lines.

It soumds like a fuel problem to me, possibly a defective pump or pump relay.

Thanks for any ideas

Chris

Answer
Hi Chris -

If the check engine light is NOT on, please check the following:

Replace the ignition module located in the distributor. Especially if the engine dies when warmed up.

You can check the fuel system. Next time the car does not start, shoot some starting fluid into the intake boot. You will have to remove the boot, or a vacuum hose going into the boot and shoot the fluid in there. If the car starts and runs for a second or two, then it is the fuel pump.

Hope this helps -
aloha
