Why wont your f-350 start when its warm but will when its cold?

User Avatar

Asked by Wiki User

One possible reason could be a faulty fuel pump. When warm, the fuel pump may not be able to maintain sufficient pressure to deliver fuel to the engine, causing starting issues. Another reason could be a problem with the ignition system, such as faulty spark plugs or ignition coils, that only becomes apparent when the engine is warm. It is recommended to have a mechanic diagnose the issue to properly identify and address the problem.

Can the key prevent an ML320 from starting?

User Avatar

Asked by Chance

Yes, a faulty key or malfunctioning key fob can prevent a Mercedes ML320 from starting. The vehicle's immobilizer system may not recognize the key, leading to an inability to start the engine. In such cases, it is recommended to try using a spare key or to have the key reprogrammed by a dealership.

Your 1989 Mercury Topaz will start but won't stay running What should you check?

User Avatar

Asked by Wiki User

If your 1989 Mercury Topaz starts but won't stay running, you should check the fuel system, including the fuel pump, fuel filter, and fuel injectors. Additionally, check the ignition system for issues with the spark plugs, ignition coil, or ignition module. Finally, inspect the air intake system for any blockages or leaks that could be affecting the engine's ability to run smoothly.

How do you change the starter on a 93 Topaz?

User Avatar

Asked by Wiki User

To change the starter on a 1993 Topaz, first disconnect the battery to prevent any electrical issues. Locate the starter under the car, near the transmission. Remove the bolts securing the starter to the engine, disconnect the wiring connections, then install the new starter in reverse order. Be sure to test the new starter before reattaching the battery.

Why will your car only start after rocking it back and forth?

User Avatar

Asked by Wiki User

Rocking the car back and forth may help the car's fuel pump to pick up residual fuel and deliver it to the engine. This can sometimes be enough to give the engine the boost it needs to start. However, this is likely a sign of an issue with the fuel system, such as a failing fuel pump or clogged fuel filter, that should be addressed to prevent further problems.

How do you change the battery on a 2003 Cadillac CTS?

User Avatar

Asked by Wiki User

Make sure the keys are out of the ignition first. Then check to see if your vehicle has any braces holding it in place. Once you've taken any braces off, disconnect the ground wire(black), it useally takes a 1/2 inch wrench. Then take your hot wire off(red). These are all the workings of a person being self sufficient. Good luck.

bad ignition switch. the fuel pump will not turn on unless the key is in the ignition and in the on position. your battery is probably not strong enough to trn over a starter or the pump itself has shorted out from an issue before or at the sending unit

Why might a 1990 Mercedes 300e not start?

User Avatar

Asked by Wiki User

I had this problem that was intermittant on my 1992 300E. after alot of searching, they discovered it was a crankcase sensor that was broken. does not show up on computer. it only happened when the engine was warm. the car would shut off after i had driven it 10 miles and would not restart till it cooled down. ANSWER 2 I think you will need to give LOT more information than this. Dead battery, corrosion built up on battery terminals, dead fuel pump, bad sensor, blown fuse, blown wiring, corroded wiring, bad distributor, bad spark plugs, out of gas, clogged fuel injectors, blown motor, dead cat caught in your belts, packrat taken up residence in your crank case, you ran it with no oil and it has seized up, I mean I could really go on and on. Please give specifics.

1999 neon new starter just clicks?

User Avatar

Asked by Wiki User

If you have already replaced the battery, then you have a few other things to look at.

  • It could be the starter itself
  • it could be the starter solenoid which might be integrated with the starter or mounted somewhere in the engine compartment. You can find it by tracing the thick positive wire (red - about the size of a finger) to where it goes. If it goes directly to the starter then the solenoid is integrated and more difficult to test
  • It could be the positive wire itself and is not making a good connection to the battery or starter/starter solenoid
  • It could also be the ground wire (Black - about the size of a finger). If this wire is not making a good connection from the battery to the engine block, it will keep the starter from working

I would start with the wires, making sure you have a good connection and then work your way to the starter. The clicking is usually a result of the starter not getting enough current to crank the engine.

Why does a 1996 Ford Ranger XLT 4.0L start when you cross the posts on its solenoid but not when you turn the key in the ignition?

Asked by Jwm00

the solenoid itself is probably bad, if not that probably the ignition switch I agree 100%, check the solenoid first then the switch.

You have a 1991 Plymouth voyager se and it turns over but wont start we have checked all the fuses and cant seem to come up with anything we checked for spark and have none what else should we check?

User Avatar

Asked by Wiki User

Go back to the basics, look at fuel delivery, ignition and compression. If you have all 3 and everything is adjusted properly, the engine will start. Try spraying a little starting fluid into the air intake while someone is trying to start the engine. If the engine briefly catches while you're spraying starting fluid, the problem is fuel delivery.

What happens if the crankshaft positioning sensor fails?

User Avatar

Asked by Wiki User

If your car uses VVT(Variable Valve Timing) or adjusts its ignition timing it could cause poor fuel economy, misfires, keep the car from starting. If the car is fuel injected the timing of the injectors is tied in with that too. In short nothing could, if the car manages to keep running it could lead to a blown motor depending on how you drive.

Could a bad key switch cause the positive battery terminal to get hot?

User Avatar

Asked by Wiki User

No, the battery terminal should be able to handle as much electrical current as the vehicle should ever use, WITHOUT heating up. Clean or replace any battery terminal that is getting hot.
