It's a 2007 Chevy Malibu LS can it be the fuel pump cost it not to crank or start


Bad fuel pump will not cause it not to crank, but can cause it not to start. Test with fuel pressure gauge. If it will not crank, entirely different issue=bad solenoid/starter, bad battery connections, bad ignition switch, relay,wiring.

Car wont start not the battery


Starter switch, starter relay, or starter motor. If it cranks, but don't start, check fuel pressure. If pressure is not good, then replace fuel filter, fuel pump relay, and/or fuel pump (in that order) If fuel pressure is ok, then its ignition. check and/or replace coil or igniton module.

It wont turn over we have checked the ignition changed all teh relays. it will start on occasion but after once it wont so anything but click once. not the starter or the ignition and the battery is brand...


If the engine doesn't turn over it is not a fuel issues as fuel will keep it from starting. However the engine will still turn over what is more likely is a starting system concern since it just clicks it is probably the starter or starter circuit. again the fuel pump cut off only turns off power to pump which will cut fuel.. engine will still crank.

Car wont crank unless pop-started.


I would have that starter tested. It could be intermittently engaging and disengaging. This can happen to the starter drive. I`m not sure why it cuts out after you jump start it,since the alternator takes over after cranking the engine. Unless the starter drive is sticking. My other thoughts are on a fuel pump problem.Or fuel problem period such as an obstruction of gas getting to the engine. Fuel filter maybe or fuel pump relay!

My 92 lincoln town car will not start i have replaced the starter, the neutral safety switch and the battery but when i turn key nothing happens but can jump starter and will crank


Yes there is a starter relay in the wiring diagram.
The yellow and lite blue wire goes from the starter solenoid to the relay. There is a yellow wire from the relay to a 30amp fuse. The key switch powers thru the neutral safety switch and then powers the relay on.

My car wont start


a) Do you have crank no start? (see entire write up)
b)No crank no start ,No dash lights?, ( battery, battery cables, ignition switch,,starter relay)

If you have symptom A then the affected items are , ignition switch, battery, battery cables, starter, starter relay ,coil, coil pack, ignition module ,Distributor cap ,rotor, (if applicable) spark plugs and wires.
The best thing to do is to first make sure your timing belt didn't break. As long as the engine cranks you can do this. Give the battery a 3 min charge . Then have a helper crank the vehicle while you observe the rotation of all the pulley's and belts. They must rotate together. If the vehicle has a distributor remove the cap, ground the coil wire and remove fuel pump relay ( to disconnect the pump for testing)and watch the rotor as the engine is cranked. it should spin. If this is a-ok your worse nightmare is over.
Now we have eliminated the timing belt as being a cause. We now have to charged the battery again for three min and load test it( this is best done by a repair shop a load tester is expensive .If the battery if more than 5yrs old you may want to replace it.
If battery does not pass load test replace it.
Whatever you decide the rest of the items can NOT be checked out without a fully charged battery.
Check ignition switch and starter relay for B+ going to them and leaving them. Check starter circuit. Make sure B+ is making it to starter ( use a digital voltmeter). If B+ (12 volts) is making it to the starter and it doesn't crank then the starter is defective. Verify this by removing the starter and have it bench tested.
If starter cranks now your into coil testing . First thing reconnect the distributor.
Pull a spark plug, hook it up to a spark tester and ground it, now crank the engine if you get spark coil is ok and in all likelihood so is module.
If you don't get spark test for spark at the coil wire.
If you get spark here and don't get it at the spark plug wire problem is at distributor cap , rotor or spark plug wire. If plugs look bad use a fresh plug to do testing and naturally replace them.
If all of the above are a-ok.
Next is fuel checks. Reinstall fuel pump relay
Easiest fuel check is to put key into ignition cylinder and turn to on position. Lister for pump to buzz or hum. if it doesn't then check fuel pump relay for B+ going to it and leaving it and going to the pump. If B+ making it to pump and it doesn't turn on the pump is your problem. If B+ not making it to pump either the relay or the ignition switch is defective.
Naturally if the pump is defective have a repair shop do the repair . Its dangerous and a real pain.
Good Luck
Now the cutting out after running fora whilrcoild have caused by the coil, ignition module, fuel pump.
We kinda have to get the car to start first to be conclusiveas to why it cuts out.

Security on. car wont crank. can trun key wont


verify that you have a fully charge battery and that you have the same amount of voltage at the battery as at the starter when the key is turned to the start position. If not repair fault at positive cable either at battery or at starter. If voltage checks good. Use a remote starter and turn key to the on position and try to crank over engine with remote starter. if engine cranks over. You have a defective starter solenoid and starter must be replaced.

Test for fuel cut off relay


Sam so right now you have crank no start,or no crank , no start. Not clear.
If its no crank no start.Your looking at battery, cables, ignition switch , starter relay.
If its crank no start, you know that B+ is making it to starter. Ok now listen for fuel pump to buzz or hum when you put key in ignition and turn to on position. No buzzing or humming fuel pump or relay.
make a set of jumper cables run them from battery to fuel pump, Does the pump run? If yes. The pump is good relay is not. If pump doesn't run then its the pump. Remember when you do this test you don't need the key in ignition Battery doesn't have to be connected, because your bypassing the control circuit.
