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.

BOUGHT BRAND NEW BATTERY NOW CAR CUTS OFF AND IDLES REALLY LOW


WHEN YOU DISCONNECT THE BATTERY THE ENGINE MANAGEMENT SYSTEMS PCM LOSES IT MEMORY INCLUDING ENGINE IDLING.THE COMPUTER WILL HAVE TO RELEARN THE OPERATING VALUES. IF CAR DOES A LOT OF STALLING AT STOP LIGHTS AND STOP SIGNS. GO BY FORD DEALERSHIP LET THEM REPROGRAM THE PCM.PROBABLY CHARGE YOU $35.00 DOLLARS. TO REPROGRAM PCM.

I have a 1995 caddy. i replaced the alternator, wires, spark plugs and gave it an oil change. I also put a brand new battery in it. i also changed the ignition cylinder. it did fine for about 30 minutes....


Even a new alternator and/or battery can be bad. You should have them load tested to verify they are working. You should also check the alt plug to make sure it is seated all the way or else it won't charge.

The truck stays on as long as i'm driving but whn i come to a stop or slow down it dies and i have to restart it. I thought maybe the alternator, would that be right? Also the lights start on the dash fade...


My truck is manual and is idling rough at low rpms, it kinda surges and rpm starts to drop like between 500 and 900 rpm as well.

I have trouble starting it and stalls on me.

I have changed the alternator, starter, battery, battery cables, rotor, distributor cap, spark plug wires, spark plugs.


As for the dash light going out, mine does that too but on the left side (gas gauge side), I just usually apply a firm tap on the left side of the black part of the panel and it turns on.

Idled high, replace IAC and PCV, now idles low and stalls


On modern day cars the parts that get fitted need to be adapted to the ECM using a decent diagnostic machine. I bet that this was not done and the car is now suffering as a result.
Something to try is resetting the ECU, simply disconnect battery for 10 minutes, reconnect, then start car from cold *without touching gas pedal* and leave idling until the rad fan comes on (this resets all the base idle settings) then take it for a drive - hopefully will solve the problem

How do I uninstall and install an alternator on a '93 thunderbird??


ericka1 hold up on the alternator! You have a new battery in the car, now what's going on? When u turn the key on, does your engine turn over (crank)? The alternator charges the battery when the car is running, if u have a new battery in the car, it should start, even if the alternator is bad. The alternator would cause the battery to lose it's charge if it is bad. So, 1st thing to check (if car won't start), is there spark at the spark plugs, and is fuel getting to the spark plugs. You must have both for the car to start and run. Check that out 1st, and provide info, we can take it from there.
