Remember that the relay only will send power to the fuel pump for only 3-5 seconds after the key is turned on. You will need someone in the cab cranking the engine over while you test the circuit to the pump. Make sure you are testing the correct wire. If the engine will start with starting fluid, then there is a fuel delivery problem. Connect a fuel pressure guage to the fuel rail. If you have the required pressure, then you may have a computer that is not grounding the injectors. If you have no fuel pressure, you may have a inoperative fuel pump or a clogged fuel filter.

Drove to the store,turned off the car,5 mins later tried to start it and all it does is crank and crank but wont start.NEVER had a starting prob. before! alternator is good,battery is good,starter is...


Yes, they can. With no warning whatsoever, in some cases. Do you not hear it turn on for a couple seconds with key on? Try some starting fluid sprayed into the engine, then crank it. If it fires up and runs a few seconds, you know it is a gas problem.
The definitive test for a bad pump is to check for power on the pump wire at the gas tank connector, when the engine is cranking over. If power there and no pump, the pump is bad. If no power getting to the pump when cranking, the pump circuit needs checked-check the fuel pump fuse, there is also a fuel pump relay under the hood.

Will not start will crank will start with starting fluid but when quit spraying eng quits


`Probably the fuel pump in the tank has stopped working. Verify with a check for power at the gas tank connector: When the engine is cranking, the fuel pump wire should have power on it-use a test light or voltmeter. If the wire has power, but pump will not turn on, the gas tank will have to be removed to replace the pump.
Just by turning the key to on, not start, will or should cause the fuel pump to come on for about 2 seconds to pressurize the fuel lines and put gas under pressure against the fuel injectors. If you don't hear the pump buzz on for a brief time, you know you need to check the fuel pump circuit. Check fuse, check fuel pump relay...but the easiest way to verify a bad pump is to check fuel pressure, or check for power at the gas tank when the engine is cranking. No power is a fault in the circuit (fuse, relay, wiring), power available to the pump but no pump means the pump will have to be replaced .

Car won't start sometimes just had the fuel injectors cleaned out


The most common cause of a not start like this is a failing fuel pump inside the fuel tank. Buy an can of spray starting fluid and the next time it doesn't start spray the fluid into the air intake of the engine and crank it over, if it starts and then stalls as the fluid is burned off then you found the problem, no fuel pressure. Also run a fault code test on the electronic engine control system, Autozone does this fro free.

Turns over but won't fire


If a starter is able to crank the engine but it won't start you usually have either an electrical or fuel problem. It's also remotely possibly that it's compression.If an engine has proper fuel, spark and compression, it will start when you crank it. So your challange is to find out which part isn't working right. Start with fuel. Spray a little starting fluid into the air intake while someone tries to start the engine. If it starts briefly when you're spraying starting fluid, you probably have a fuel delivery problem. That could be injectors, fuel pump, fuel filter, relay, fuse... who knows what until you check into it.If it doesn't start with starting fluid, check the spark. Pull a plug wire and attach it to a spare sparkplug and set the plug on a solid metal part of the engine. Have a helper crank the engine while you watch the plug. If you have a good spark, it might just be out of timing.In any case, you'll need to start isolating the problem. Find out which part isn't working then you'll know what to replace/repair.

Have to pump gas to start


Check your fuel pressure it should be 9-13 psi with key on and engine off.If its not within these specs then replace the fuel pump and filter.

Try spraying starting fluid into the intake of the air cleaner while someone else starts the car. Continue spraying the starting fluid for about 15-20 seconds. If the car starts, more than likely your fuel pump is bad. Check your fuses, and make sure you are getting power to the fuel pump. jpwtruck@yahoo.com
