The following are the general instructions on the start of diagnosing any electronically controlled engine or transmission problem.

The engine and the automatic transmission (transmission control is only for automatics, engine is still computer controlled no matter the transmission type) in this vehicle are computer controlled and in most cases when a fault occurs a fault code is stored in the memory of the computer control module. There are exception to this, such as the Mass Airflow Meter and fuel pressure problems. What must be done is to have all the basic testing done such as a scan of the system for fault codes as well as a check with a live data scanner tool for engine functions that are not within range of normal, a trained technician is required to know what is correct and what isn't, then based on careful diagnostics done from a factory repair manual the correct part is replaced or the wiring repaired or the computer replaced (known as the PCM or ECM,ECU), which is very rarely the problem. Other basic checks must be done as well such as mechanical problems with the engine as well as engine state of tune and mileage on the engine. The transmission can have mechanical issues as well such as no gear engagement at all or a failed pump or other pressure related problems. Also engine mechanical problems can and do cause many drive-ability related problem such as rough idle and other symptoms.

SOURCE: Ford Escort 1998 fuel pump not working.

good old ford lol, try looking at the crank sensor its located at the front of the engine tucked in right hand side of exhaust manifold and gearbox, two pin plug, i have also known these to have no end of faults with the fusebox.
easy to remove, and solder the connections inside they all suffer eventually, if your not to handy with cars i recommend taking to a auto electrician, easy if you know how. Good luck Davelee

SOURCE: car wont start .

You will not be able to hear the fuel pump on that model. First you have to determine if you get fuel and have spark. If it is a fuel problem, replace the DME relay first. Very common. They act up and fail without warning. Part is cheap and located in the fuse box. Next would be the fuel pump.
If it is spark related it may be the Flywheel Reference Sensors. There are two and the cost about $100 each.

Good Luck.

SOURCE: 2004 Ford Freestar missing Possible fuel pump?

You have to get a pressure check to make sure the right pressure is pushing gas to the motor,and check for any leaks where air might be pulled into the line,which would cause a stuttering engine.

it could be ignition coil(coil pack). misfire and vacuum leaks gives you engine light's on. and if fuel pump or filter not good, engine wont start.

My Mitsubushi Space Star Car won't Start. What can I try?


spark plugs are deep in the head yet you should get all the the old fuel out first, stale fuel wont ignite and will also clogg fuel filter. you need a mix of atleast 70% new fuel even then its not good for the injecters. If its a manual gearbox a tow start is a quick fix although no go for auto's. cant be much wrong if car was fine when parked, plugs-fuel-filter and possibly fuel pump for sure. If that doesnt fix take plug out put in lead and crank engine to be sure you have spark even just put any plug you know works in lead leaving your plugs in engine just to check for spark y turning over engine looking for spark on plug good spark will be blue but any spark is good.

I paid yesterday for my question i recieved about the 1987 dodge aries 2.2 motor k series didt recieve an answer? the car cranks up but dost start


Check to see if it's fire or fuel. Take one spark plug wire off and put on spare new plug, Place spark plug on engine where the tip is grounded against block and while someone trys to start car check to see if there is spark arcking between tip and insulator on plug. it,s best to do this in the dark. if it sparks, try putting a little gas in intake then try to start if it starts or trys to start, yo know it's a fuel problem. Change fuel filter first, f no change check fuel pump. If no spark check ballast resister on firewall or fender

2004 dodge 5.7 hemi stalls while driving


with a problem like this you must surly have a check engine light on ?
To answer your question yes an EGR valve could cause this problem on a hemi ! But would act up more cold .
And No the key thing wont work on this year of vehicle , you need to have a scanner for OBD 3 to retrieve the codes .
This sounds like a fuel problem to me have you checked fuel pressure ? and for a tuneup , remember the hemi takes 16 spark plugs it could have some of them miss firing .

Ok i have a 1999 hyundai accent wont start changed fuel pump and it started ran very bad very! turned it off wouldnt start back up again checked spark plugs no spark and no power going to fuel pump we are...


Changing the pump doesn't affect the spark so lets start a that the beginning?? Why was the pump replaced and was it running fine before changing the pump? Also plugs could be fouled as well but if it was working fine before the fuel pump it will be fine afterwards if getting gas and the fuel pump was the problem., Also how did you verify no spark??

Car will not start. new battery, new fuel pump, new starter


Have you got spark at the plug leads
Put a spare plug in the lead and earth it to the engine block spin it over if it sparks then undo the fuel line to engine and if nothing coming out when you turn the key then you have a blocked fuel filter replace and try again ,,that should fix your problem..

2005 Hyundai Accent won't start


If it is the timing belt you should here misfire and this is how you check for spark, remove a lead from a plug at reach distance unloosen plug with a spark plug socket put plug into the lead you removed and hold close to something metal while someone turns the key and you should see a spark come out and hit the metal, if not try replacing the rotor button and coil.
