1996 Dodge Avenger Question: car wont start
I was driving down the street and the car just died with no warning and now wont start. sounds like the fuel is not getting to te engine. I can hear the fuel pump when i turn the key but i cant get the car to start - Visitor
If the engine cranks over the battery and starter are most likely OK. Keep in mind an engine must crank over sufficiantly fast enough for the engine to suport combustion and run. The engine needs three things to start, fuel (gasoline), ignition (spark) and mechanical integrity (it must develop compression in each cylinder to start ie mechanical components must be in synchronization with each other. If it had run well previous to this no start condition chances are the engine is well mechanically.If the engine had run rough, driven poorly, made unusual noises, "ran hot", or switched off while driving the problem may actually be mechanical. Start with the basics and make sure the engine has strong and even compression, engine creates adaquate vacuum ect.... Had the Check Engine light been on? Check to see if the engine has "lost" spark or fuel which could be due to any one of a number of sensors having failed or the fuel pump or related components are not delivering fuel to the fuel injectors. The engine uses many sensors to report engine temperature, air flow into the engine, crankshaft and crank shaft position sensors to allow the computer in your car to make calculations controlling fuel and spark to the cylinders. It is hard to speculate without being able to hear the engine crank over and do some preliminary tests to determine the cause of your no start condition. Check for fuel pressure (you will need a fuel pressure gauge and look up the specified fuel pressure for your vehicle). Remove the fuel hose that goes to the fuel rail and get a friend to crank over the engine to see you have adequate fuel volume (you should have approximately 1 pint of gasoline in ten seconds of cranking). Off course take proper precautions as gasoline is highly flamable. Next "listen" to the fuel injector. Using a mechanic's stethoscope (or use a long screw driver placing the handle end up to your ear place the metal tip end of the screwdriver against the body of the fuel injector), get a friend to crank over the engine while you "listen" to the fuel injector listen to each injector at the same point of the injector body. You should hear "click, click, click" as the injector is electrically opened and closed by the computer. If the injector is not being triggered you will not have fuel getting into the engine's cylinders. Disconnect the electrical connector at the fuel injector with the ignition key in the "on" position, (next position after the accessory position) you should have 12 volts at one of the two wires at the injector. This true for most vehicles but you need to consult a workshop manual for your vehicle to see that this is true for your vehicle. When the engine is running the second wire at the injector gets (triggered) grounded by the computer in your vehicle many times a second controlling exactly when and how much fuel gets injected into the engine. There is a company that independent auto repair shops get their information from, this same information is available inexpensively for people that work on their own cars.. The information is year make and model specific, covering repair procedures, torque specifications, fluid capacities and specifications, service bulletins, component locations, wiring diagrams ect....

check your timing belt.should be a alittle piece you can unbolt on top of the belt cover to look inside.use a flash light to see down in there - trucker70
Sensor failure inside the distributor can cause intermittent stalling or a failure to start. In addition, the wires to the distributor are susceptible to internal damage, which can cause the same s...
wont reverse drive or stay n park have to have parking break on.
I pulled in my driveway and placed the car in park. The car rolled forward and I depressed the breaks. It did it again so, I turned off the car. Now it will not start at all. The lights come on, an...
Car was running fine and then just died. Now wont start but if you put starting fluid into engine directly it tries to start up. Changed fuel pump and it kicks on. Seems like there is no gas to the...
...bit later the car dies out and just the day before changed out pcm module on it. and know the car wont start. sounds like it wants to but doesent.
