Hi gang.

I have a 93 max, with the ve30de dohc. I was driving and the water pump went out. The car is turning over, sounds like it is not getting gas. I was wondering if a relay or fuse might have blown. I have checked all the fuses, have looked at the relays I could find but could not tell if the were good or bad. Just seeing if someone might send me in the right direction. I have replaced the water pump.

Thanks
Mike

Sweet, fast, when running.

 

how is it turning over, but not starting. Do you mean it dies shortly after actually running?

Did you replace the thermostat? They can stick after overheating, but I don't think that's related to your issue.

 

Its cranking, I was driving and it just shut down. I saw it overheating and tried to get of the highway and it just shut down. I was thinking that somewhere in the electrical or computer system, there was a relay or fuse thatblows after the system tells it to shut down when it get to cetain temp. I was just glad it still turned over after the overheating. Maybe something to say for synthetic oil.

If the car shut down I would be looking for melted pieces in the wiring. The underhood environment is not a good one for plastic and when a car overheats it just gets that much worse. My Dad overheated my old Dodge Polara I have and it melted every plastic piece under the hood.

 

Depending on how hot you over heated the engine you could have blown a head gasket. If all fuses and connections look good, and you're getting fuel and spark the only thing you're missing is heat which we get from compression. Install a eng comp tester and keep your fingers cross.

 

It only sounds like it is not getting gas. All connecters look ok, no melting. I have no leaks either. Thanks for all the input

Had a similar problem on a '90 SE, only that mine never overheated on the hgwy. As long as I'm driving it was fine, but as soon as I shut off the engine, it would never restart, sounded as tho it wasn't getting gas, would fire but never start.

I would have to wait until it cooled down then restart.

Finally a tech at a local Nissan dealer told me the problem was a sensor that's connected to the flange that houses the thermostat (see pic below).

As soon as I changed the sensor the problem went away. Apparently it was sending a false reading to the computer that the car was overheating, thus not allowing the engine to start until it was cool.

I have included a pic for you to see exactly what I'm talking about.

Good thing: the sensor is about $27.00 from nissan, and if you are going to change it, go ahead and change the harness too, about anothr $11.00.
