1999 Dodge Intrepid will turn over but wont start what can i do?

Answer 1

There are three other things a car needs to start and run besides having the engine turn over. The first is spark, so check the plugs and coils. also check the fuses to the ignition, engine computer and fuel pump. The next is fuel. Make sure there is fuel getting to the engine. Check to make sure the pump turns on when you turn the key (there'll be whine from the rear of the car for a second or two). If not, check the relay and wiring using a test light where the relay plugs in (there's a fuse box under the hood where the relay lives). Use a wiring diagram to find the control and load wires. The control wires will have one lead to ground (the engine computer) and another that has power when the engine is cranked. The load wires have one for the fuel pump and another constantly on. If these check out, replace the relay. If the pump doesn't come on after the wiring and relay check out, it may need to be replaced (this lives in the tank).

Another common problem with this car is if the chain (2.7 liter) stretches out and screws up the valve timing or the belt breaks (3.2 or 3.5 liter). These will not let the engine start either.

In the case of the 2.7 liter, the chain, guides and water pump will need replacement (very common failure with the 2.7liter) and these parts are about $500 to $750 not including labor. If this is a 3.2 or 3.5, the belt, tensioner and water pump will be about $150, not including labor.

I would get a service manual for this car if you intend on keeping it and take the car to a competent mechanic to check this out. These are not really easy to do yourself and you'll save more money in the long run.
