Might be you alternator. Happened on my 1997 grand marq a couple of weeks ago
how to changing engine coolant on a 1993 mercury grand marquis gs.
what is the part called where the water pump is connected to on a 1996 mercury grand marquis -------------------------- That would be the engine
MY 93 GRAN MARQIS EGR VALVE IS LOCATED AT THE VERY REAR OF THE ENGINE BELOW THE INTAKE MANIFOLD AND A LITTLE TO THE RIGHT SIDE OF THE CENTER OF THE ENGINE AS VIEWED FROM THE RIGHT-FRONT FENDER. IT IS A LITTLE DIFFICULT TO SEE BECAUSE THERE IS STUFF OVER THE TOP OF IT. I DON'T KNOW IF THE 98 IS SIMILARLY SITUATED, BUT THAT WOULD BE A GOOD STARTING POINT.
That's something you would have to look at yourself, we can't give you an answer unless you tell us in more... er.. detail.
Likely the fuel filter is clogged so you need to change it. If you can keep the engine running by pumping throttle a few times at start up, and then it runs, check the filter; cost about $10.00. On My 1999 Mercury Grand Marquis I had to replace the Idle air control valve because it did stay running until it was warm
I would first have the battery checked. It sounds like a weak battery. It could also be the computer. In fact, there are a number of possibilities but the first thing I would check would be the battery.
That depends, all I can think of is you drove it in deep water (over five inches) if you did, then it might have gotten water in the exhaust.
I changed oil on my suzuki grand vitara and it would not start up
I was looking at a ( 1998 ) Mercury Grand Marquis Owner Guide and it shows the body as being ( 78.2 inches wide ) I'm not sure how much the outside mirrors would add to that
On a 1999 Mercury Grand Marquis : The Original Equipment engine cooling thermostat would have been ( around 192 * Fahrenheit )
