Car cranks but wont start. I have no power to the fuel pump and no fire to the spark plugs. Fuel pump fuse, ign fuses and ECM fuse are all good.
Well if spark quits fuel usaly will to computer will do this to stop cadilac converter from filling with fuel!and causeing a fire saftey feature!!!!okay disconect battery wait a couple of minutes reconect! turn key on postion do not start or crank!off then on until you hear a GRRRRunt that is your fuel pump that is what you should hear turn your head to the right towards back seet and once you hear it that means pump is good then crank it then spark should quit if the coil packs a r bad then you have your problem if so test for spark also if you have eng light on cut the case hook up obd 2 scan find the fault and fix THIS IS WHAT I WOULD DO CHEERS!
2002 kia optima spins over no fire to coil packs
A car that cranks over but doesn't start or does not fire, in many cases will be
due to a bad fuel pump, a broken timing belt, an inoperative cam sensor or
crank sensor. Also this problems are related to faulty spark plug. Check the
spark at spark plugs when you start the car. Do you notice any spark. Actually
you should see. If in case there is no spark then it's a spark plug problem.
Also the coil pack gives power to spark plug. So check the voltage at coil
pack. It will show 12 volt.If there is no voltage noticed at coil pack then its
faulty coil pack that has to be replaced.If all the possible options checked
out ok then check the car starter. The starter gets power from battery to start
the care. If the starter is faulty then it will not let the car to start. Also
check and confirm that there is fuel in the car. If its very low fuel then in
some cases this causes the problem. Also check and confirm that fuel pump is
functioning properly and the fuel filter is not clogged. One of the easiest
ways to check for a fuel pump related problem is to spray a little starting
fluid into the air intake while trying to start the car. If the car starts
momentarily, then there's a good chance the fuel pump is not working or the car
is out of gas. You can also listen for the fuel pump's humming sound when the
key is first turned on. Also if a inoperative fuel pump is suspected, a good
technician will always check to verify there is power and ground being supplied
to the pump, to eliminate the possibility of a bad relay or electrical issue.
Fuel pressure can be checked with a pressure gauge and if there is pressure,
pulse can be checked at the fuel injectors in several ways including the most
common, with the use of noid lights. If the injectors don't have pulse the
engine won't start. ---------- This troubleshooting tips will help you to solve the
problem.Thanks.Helpmech.
Most probably its a low fuel pressure related problem.Get the fuel pressure checked.If its low then this is faulty fuel pump and clogged fuel filter issue.the other possibilities are,-----
