Repeat warranty service. I would have left it at the dealer so they could do their job.

SOURCE: Turn key 4x to build pressure, on 4th try complete Start seq.

is the engine actually cranking when it doesnt start or do you hear just one "click" each time you turn the key? if the engine is cranking, i would suspect a fuel problem, possibly fuel filter if it wasnt changed when the fuel pump was done. if it is not cranking and you hear one "click" upon turning the key, i would suspect faulty starter or connection problem.

So you have power there, why not try a little whap with rubber hammer near it while key on to see if it will do anything. I;d try it just to see if it will come back to life.

It wouldn't hurt to change the filter, but it sounds like you got a bad batch of gas, if it was running good before you got gas.
Get a bottle of dry gas and put it in the tank, if there is any water in the gas, that will clear it out, also it wouldn't hurt to put a bottle of fuel injector cleaner in the tank, I use that stuff all the time to keep the fuel system clean.

SOURCE: how can i change fuel filter in my grand marquis

you will need the proper Quick Disconnect tool, Look on the Frame rail for the filter, remove filter from the spring type retainer, remove the safety clips on the lines but not remove them completely, insert the disconnect tool & push into the fitting of the fuel line, push line & tool into eachother then pull filter away from line, if not done properly you will have a big problem putting the line back on

The dealership shoud be able to tell you!
Possible fuel problem.
Cycle the ignition 3 times on and off:5 seconds per cycle to "prime" the fuel pump.
Add starting fluid into intake to see if the engine fires up to help with fuel diagnosis.

My guess is under the hood on the firewall. There is a plastic cover which you pry open to expose the filter compartment.

1990 grand marquis has 40 psi to fuel rail. Injectors dont seem to open. Car wount start. Car starts and runs when fuel is sprayed directly into intake.


A lot of cars, trucks, SUV's, Toyota 4x4's will not start , until COMPLETELY assembled. I have left off just the last air boot between the filter & intake throttle body, & NOTHING. Then sprayed a touch of "starting fluid" & Varooom. It came to life. I checked fuel rail, it checked out, still nothing. I gort angry, had picked up the vehicle cheap, for a quick "flip" for some extra money while the wife was hospitalized. I didn't have any more time to fool with it. Put the boot back on between the filter & throttle body. Put a For Sale sign on it. Turned the key....to turn the whell to roll it down into the yard, & it fired & ran. After scratching my head a while, I took the boot off, NOTHING ELSE, no start.sure it is completely assembled.

I have a 98 Mercury Grand Marquis. Won't start


Check in the trunk and push the button on the Inertia switch. It should be on the drivers side of the trunk.

If this does not help, get a fuel filter and change it. If you can possibly get a fuel sample from the disconnected gas lines do it.

The new 10% gasohol will separate if it stands a few months. You may need to add fresh gas with a drying chemical like "Heet".

Cranks over but won't start. Is firing. Does it have a fuel filter other than inline?


there is a screen on the pump which is located inside the tank. turn the keyon but dont start it and have someone stand by the fuel tank and listen for a humming sound. It will only last a second or 2. If you hear nothing then your pump is bad.
