I understand a failed or worn out fuel pump
but replacing all the injectors.

It makes no sense to replace one,unless it
completely stopped working.

NO PARTS EVER get replaced until they fail
some type of test.

Do you have spark,fuel pressure,tps input etc
Crank signal

Have to know what all the parts do and how to test them

My car wont start engine turns over but doesnt start like ist recieving no gas


Considering it ran fine after pump replacement for awhile then it is probably a fuel issue. Couple things it could be. 1. you could have a ton of sediment in gas tank and it keeps clogging up your pump. 2. you could have blocked fuel filter and or clogged injectors.

Have a 1999 dodge ram2500 diesel. been running fine. parked for about a week (have had temps in the low 20's). started and ran for about 5-10 sec (rough). now will only crank and not start. Replaced lift...


the best advice i can give you is bring it into a warm garage and let it heat up, then treat your fuel with anti gel solution run it through your injectors by running engine and this should not happen again, seems like your lines are gelled up and you don't have proper pressure.

Does a fuel pump continue to pump fuel with ignition on when the fuel line is diconected from fuel filter The car wont start no codes found it has done this a few times this year it runs fine when running...


you have a bad fuel pump it's in the tank and only comes on in these conditions.
1. ignition switch turned to the run position turns on for two seconds.
2. same as above but when engine starts pump continues to run as long as engine runs. and the safety switch for blow out prevention has not been tripped.

Your problem is the fuel pump and fuel sock and the check valve in the pump. only one way to be sure and that's pressure testing. You hook up gage to fuel rail turn the ignition key to the run position look at pressure should read 40 to 50 psi and should hold for 1 minute, if you drop 5 pounds in one minute pump is bad and even if it started they could verify that the check valve is not holding pressure.
This is caused by the life of the pump by using gas with ethonal in it and your car was not designed for it, so it damages the pump and injectors and destroys the filter in the pump.

96 Jeep cherokee ran out of gas, re-fuel, won't start. No spark.


You may have to prime the fuel pump. Or replace the fuel pump if that does not work. Why do you let it run out of gas? This is definately not good for an injected motor. It will continue to cause more and more problems. Fuel injectors should never run dry.

Not starting ran out of gas,added gas and still not starting,can hear fuel pump running,smell gas at engine and exhaust.


Gas line filter may be dirty and clogged. Change it. There could be sediment or dirt in the tank that you drew up to the filter when you ran out of gas and it has built up and is blocking gas from getting into the engine.
