2001 Mercury Grand Marquis Q&A
2001 Mercury Grand Marquis Question: What causes no crank.
First code was for cylinder 3 bad plug or coil. Replaced both car ran good 20 miles. Next code bank 1 2 lean. Replaced duel filter old me stoped up. Cranked right up ran 10 miles. Cranks when wants, when it does runs good till warms up then rough idle, eventually will die. Have to wait 30 min will crank back up. Any ideas. - dustint1

So recently I bought a used car from a dealership outright. When I first bought it, there were some problems and they thought it was due to a dead battery which would have made a ton of sense. Abou...
I changed my heater core on my car......put everythin back and now the car doesnt want to start. I also changed the fuel filter and pump but that didn't solve the problem either.
repalced fuel pump, no fuel is coming out of the valve stem under the hood and no fire is getting to the fuel pump what else could it be.
