SOURCE: 1985 Grand Marquis won't start

no..i also have an 85 gr. marquis with the 5.0 engine... i changed the starter solenoid located next to the battery on the passenger side firewall of the car.. if it clicks then its either the solenoid or the starter..those are hard to kill cars with good grounds..check the solenoid..

SOURCE: '97 Grand Marquis needs a new Oxygen Sensor

its simple to do. just unplug the sensor and unscrew it. if its frozen and hard to break loose, then just heat the base the part of exhaust that it goes into.

SOURCE: 1998 grand maquis crank no start no injector pulse as well as no ignition spark. Have changed crank sensor, cam sensor, fuel pump, pcm, injectors and still no start no voltage to sensors or injectors

Car not starting or turning over indicates towards multiple possibilities. It can be issue with battery or weak battery. But if battery checks out ok, then it can be starter issue or faulty alternator or problem with low fuel pressure or no spark at spark plugs due to dirty spark plugs or faulty ignition coil or injectors getting cracked or dirty and needs to be cleaned.


To confirm the problem, the basic troubleshooting is required.

97 oldsmobile achieva wont fire changed coil pack spark plugs cam sensor still wont start


Make sure battery has a full charge and battery connections all good.
If it cranks good but won't start, have a helper crank it while you visually check for spark at the spark plugs. If spark everywhere, use a gage and check proper fuel pressure and fuel injector pulse.
If you having a problem with more than one system, I want to check for rpm signal, that usually comes from the crank sensor. Not sure why you replaced cam sensor? I always want to check sensor wiring circuits before replacing anything. Don't replace anything unless your testing points in that direction.

97 mercury grand marquis wont start after warming up


You need to determine if it is fuel related or spark related. I have seen everything from a pick up screen in the tank to a crankshaft position sensor. Check the fuel pressure when the no start condition occurs, check for spark at the coils. Does all your electrical equipment in the car loose memory?

I'm having a similar issue with my '97 Golf K2 with a 2.0 I checked the resistance to the crank sensor and it was almost 900ohms with the replacement one being 500 ohms. Changed it, didn't work.


Mine was running fine driving 70MPH on the highway and just shut off. Now it cranks, fuel pump runs and it seems to be getting fuel but still no spark. I have a coil/module on order and will try it tomorrow.


UPDATE

Replaced the coil. Coil sparks once when you first turn the key on, that's it. crank sensor has already been replaced yesterday.
Injectors seem to fire (I smell fuel if I crank it a while) but still no spark.
I have 12V to the coil and 12V when cranking.

I see tons of posts with this issue but no resolutions. Come on somebody has to have been here before....

UPDATE #2

I do NOT have an injector pulse or a pulsed signal to the coil. When I crank the car the oil pressure light blinks on and off (just noticed this not sure if it is relevant)

I do get a check engine light when I turn the key on and when cranking, thought this meant ECU was good?

Any other way to test the ECU?

Could the pick up in the distributor be bad? Doesn't the pick up signal the ECU to fire the coil and injectors, I thought the crank sensor was just a TDC reference point?

97 jeep grand cherokee is not getting spark at the ignition coil I think its the PCM


Have your crank sensor checked. It won't send a signal to fire the coil if the crank sensor is bad.

Car wont start, changed the spark plugs and wires, but still wont start up


check coils for spark if you have spark comming form all the wires and coils etc and then check for fuel and if you have these all working and still no start it could be a sensor either a cam or crank shaft sensor depending on the motor config
