Why my car will crank but wont start?


A crank no start concern is when your car has power to it, and when you try to start the car it will turn over but will not fire. There are two problems that are mostly associated with a crank no start concern. Starter is Bad.
If your starter has failed, you might get a crank no start concern. If you happen to be stranded somewhere, I would try to tap on the starter. This is an old trick used by those in the know, and sometimes it will work so you can get your vehicle to a repair facility. The reason for this is because when a starter fails, it usually binds up internally. Tapping on the starter will sometimes free the internal parts temporarily and allow you to crank and start the vehicle. If this doesn't work, you may have lost power to the starter and will have to have the vehicle towed.
Fuel Pump Failure.
Another common problem for a crank no start concern is a bad fuel pump. A fuel pump does exactly what it says, it pumps the fuel from the gas tank through the lines and to the motor. If your fuel pump is bad your car may just crank and crank, but won't start. Ironically a quick fix for this is the same as the starter. Try to tap on the fuel tank to get the car started. This may allow the vehicle to run on what's called false fuel for a while, or at least until you can get it to the repair facility. If this method fails, unfortunately it's time to get the vehicle towed.
Electrical Issues
These days most vehicles will have some form of security system in place. The most simple form of security often causes a lot of problems. If your electronic ignition switch has a security feature on it, it can fail and cause the vehicle not to start. Basically what happens, is the car thinks the wrong key is in the ignition and refuses to allow the vehicle to start. Really the only repair for something like this is to replace the entire ignition switch for faulty operation.

Car turns over but will not start


Check and make sure that the engine is getting fuel, spark and has compression........ Check all fuses.......... If there is no fuel coming from injectors but there is a injector signal, fuel pump or fuel pump electrical circuit could be bad. If the fuel pump in the tank is starting to go bad, some times but not all the time, if you get a rubber mallet and have someone crank the car as you bang on the gas tank with the rubber mallet, the engine should start. This is only a temp. fix. Depending on what vehicle you have, a faulty fuel pump can be accessed from under rear seat, trunk or the tank has to be physically removed from the vehicle in order to service the fuel pump. If the engine has no spark, again, check all fuses.......... Most of the time for a no spark issue, a crank sensor goes bad or the ohm values are out of specs. To ensure that you have a faulty crank sensor, you can either rent or buy a fairly inexpensive scan tool to check for trouble codes and possibly look at live data the the RPM signal. If you crank the engine and the scan tool does not pick up an RPM signal, more than likely, you have a bad crank angle sensor. If the engine has no compression, if the engine has a timing belt....... check and make sure that the belt has not broke, skip a couple of teeth due to bad tensioner or teeth stripped out at the crank due to oil contamination. If your engine has a timing chain, check to see if chain is stretched, broken or skipped couple of teeth due to bad hydraulic tensioner. Hope this helps..........

How to remove and reinstall a fuel pump for a 1998 Dodge neon 2.0 SOHC


Hi,
Not extremely hard, but it is in the fuel tank, so you will need to be able to jack the car up at least about 2 feet and support it on jackstands/blocking. Takes about 2 hours. Steps:

Disconnect negative battery cable.

Make sure transmission is in park and chock both sides of front tires.

Raise and support vehicle.

Siphon fuel from tank, make the tank as empty as you can.

Loosen the tank support straps but do not remove them fully yet. (use a bunch of WD-40 or liquid wrench on strap bolts to facilitate removal)

Disconnect the feed and return lines and electrical connector from the tank, then support the tank in the center with a block of wood under tank and a jack under the wood.

Remove the passenger side support and carefully lower the passenger end of the tank.

You should be able to lower it enough to access the round pump retainer ring, gently tap it loose.

It will be a tight fit but you can maneuver the pump out now.

Clean the ring and tank mating surfaces. Swap the pump , reverse procedure to re-install.

Doublecheck all your fittings/connectors.

IMPORTANT: replace fuel filter at this time, I HIGHLY recommend it!

Lower car, reconnect battery cable, put 1-2 gallons of gas in tank.

Turn ignition key to run (not start) position. Listen for pump to be running.

Allow 30 seconds for pump to prime the fuel rail.

Check for leaks.

Start vehicle, allow to idle, check again for leaks.

I usually test the fuel pressure at fuel rail or TBI unit before assuming the new pump is good, I have gotten a few bad ones from the parts store. If you are going to do that, do it before you lower the vehicle in case you need to remove the pump again.

Please rate this answer! Thanks, Mike

Steps replacing a 1985 grand marquis fuel pump for first time alone thanks


See Figure 1
Two different electric fuel pump configurations were used on fuel injected models. One consists of a low pressure in-tank boost pump in conjunction with an external, frame-mounted high pressure pump. The low pressure pump is used to provide pressurized fuel to the inlet of the high pressure pump and helps prevent noise and heating problems. System pressure is controlled by a pressure regulator mounted on the engine.
The other configuration consists of an in-tank high pressure pump which does not utilize a boost pump.

1991 s-10 pu//////electric fuel pump not working,is it a blown fuse


i'll try to help. have you checked the fuses and the relays under the hood in the black fuse box? with the key in the on position, can you hear the fuel pump humming? you may have to turn the key on and off several times 15 seconds at a time. if all fuses are good and the fuel pump relays good, try with key on, tap on bottom of gas tank to see if the pump will start to hum. if pump does start to hum, you'll need to replace that pump soon. you may get a couple of starts out of it, but usually not very many. hope this helps and thank you for choosing fixya.com

Discovery land rover will not fire.


try taking the air cleaner assembly off you might not be getting enough air to engine
if this is the case then the throttle body needs to be maintenanced

heres another suggestion it just hasnt sucked gas to the engine to crank over sometimes they help

go out buy an electric fuel pump
find the fuel inlet source to engine hook up electric fuel pump
attach only ground to something in engine compartment
then get a can so that when gas comes out it has something to go into
tap the electric fuel pump power lead to the positive of battery let run till gas comes out make sure not to spark your working with gas
once gas becomes present detach electric fuel pump all the way set aside
hook gas line back to port and then start vehicle this should start

also with fuel filters there are 3 on a vehicle
one in engine compartment
one on chassis back by the tank
and one in the tank called the sending unit this has a filter in the tank this one could be clogged
make sure these filters are in the right position with gas flow flowing in right direction
