I have a 1990 Chrysler newyorker 3.0 w/air, and the car died all of a sudden, all fuses are good all relays are good ,(new spark plugs, new wires, about 3 months old). It gets plenty of gas, but no spark. The car has 180,000 miles. what do I do?

It sounds like you have an air flow problem. Go backwards from the throttle body to air cleaner. possible IAC valve stuck closed or open, possible Mas Air Flow sensor. The lack of air is causing the engine to die Good Luck Friend.

it doesnot crank

hello good day, reverse your air filter, make the bottom to top,, if is not work change the high tension wires

One works with the A/c, the other is for the cooling of the motor,, turn on the ac and see if the other one comes on, if it does, check the relay for the other one, or it could be the heat sensor

three things an engine needs, fuel, air, and spark. without any one of these it will rotate but not start. 1. Air - If filter is clogged it cannot get air, but it would have to be verry dirty for this to be the problem 2. Fuel - If no fuel check fuel filter, lines, sending unit 3. Spark - Check ignition, spark plugs, plug wires,
If it has no spark and this happened suddenly, as it was running, died or was shut off and now won't start it is also a very good probability that the timing belt broke.

Sounds like the ingintion coil gone. and if thats ok, the you new a new ecu

My info say's press on.Just in case your not aware you need the proper tool to remove and install or else damage is likely..Good luck

If you are getting power to the coil pack but not to the spark plugs, and you've already made sure to check your wires and fuses/relays, then it is probably a problem with your coil pack. The ignition module on my 1990 Grand Wagoneer did the same thing.

you need a new fuel pump sir.

if it will not crank have you checked all your fuses and relays? there should be a crank fuse and a starter relay. is the relay functioning propperly. next check at your starter yould should have a larger wire that is hot or has voltage on it at all times directly from the battery. there should be another smaller wire that comes from the ignition and at the keys crank position you should get 12volts on this wire this is what energizes your solenoid on the starter. not sure if you have already checked this hope it helps
