The only method that work was pulling the fuel pump fuse,wait 1 minute, crank her with out your foot being on the gas for 15 sec. Put the fuse back in , and start her up normaly. 1 st attempt she started but cut off, redid the process over , got in started her up normally, but had my foot 1/4 way down on the acclerator. She started and feathered the gas til she was fully operational. Let her stay on for about 10 minutes then took her out for a good long spirited drive.Engine rotates but will not - smile.gif

My 2005 uplander wont start, sometimes it tries to but... nothing. it cranks, acts like its not getting fuel. is it the throttle body,iac,relay or fuel pump, what???


I would first suspect the fuel pump. Do you hear it buzz on for a couple seconds with turning the key to ON, not start?
It should come on for 2 seconds to prime the line with pressure to the engine. Do you hear it? Stand by the gas tank and have someone cycle the key to on if you need to.
If you hear nothing from the tank, you need to investigate the fuel pump and it's circuit.
There will be a fuse for the fuel pump, it is under the hood in the power distribution box-the fuse/relay block. The power for the pump goes from that fuse to the fuel pump relay (also in that fuse/block) and when the engine computer signals that relay on, the power goes through the relay and then directly to the pump in the tank.
Try this test, if your pump doesn't work-test the FPR-to test if the relay is getting a signal from the computer: hold your finger lightly on the relay. now have a helper cycle the key again from off to on (not start). Every time the key is cycled you should feel the click of the relay energizing. If you feel it click and you checked the fuse and it is good, and you still have no pump coming on, then it is likely you need a new pump. Bang on the bottom of the tank, a couple of raps, then see if pump turns on. A failing pump can sometimes be turned on by jolting it like this, but it only works a time or two or three.
So now what? If the pump is working and putting fuel to the engine, then check for spark at a spark plug. Usually a sudden no start means the engine has lost either gas or spark.

Location of fuel reset button


Sorry no reset button ! You will need to do some electrical testing to find out what the problem is . You can go to www.bbbind.com for free wiring diagrams .On there home page click on technical information , five boxes will pop up , click on All TSB's and diagrams for every make and model - FREE , The next page go to the bottom an click I agree . On the next page click on wiring diagrams ,then enter your vehicle info , year ,make , model an engine size ! Then under system -engine ,subsystem fuel controls . then search , click on the blue links one at a time . Do you know how to read a wiring diagram ? If you hear the fuel pump humming it's probably not the fuel system ! Do you know how to check for spark at a spark plug ? Do you know what spark is an where to find it ? I know that a ASD relay not working will cause a no spark condition , because it supplies Battery voltage to the ignition system . No Start Diagnostic Basics EricTheCarGuy

I have a 2004 Daytona 600. It's been sitting for several years. I changed the battery, oil, gas, and spark plugs but it still won't start. Engine turns but don't know of it's not getting gas or fuel.


You should hear the pump in the gas tank turn on for 2 seconds when you turn the key to on, not start. A buzz or hum from the tank area? If yes, the pump is supposed to put enough pressure in the line to the engine and the injectors for the car to start. Maybe not enough pressure if it won't start. Change the fuel filter and try again. If no help, maybe a weak, tired pump. You will need the fuel pressure checked to compare to specs for your model . Autozone and others rent or loan fuel pressure testers.

If no noise from the pump, check the fuel pump fuse, under the hood in the power distribution center or fuse/relay box. In that same place is the fuel pump relay. Locate the pump relay from a diagram on the fuse/relay cover. Hold your finger lightly on this pump relay while someone cycles the ignition key from off to on. If the pump circuit is working right, you should feel the relay click. That should send power to the fuel pump to turn it on for that 2 second period. If you feel it click and the fuse is good, possibly the pump or the pump's ground wire is faulty. If you don't feel the relay click with key turned to on, the fuel pump circuit will have to be diagnosed. Good luck with your project. Let me know how you progress.

Its a 1993 dodge colt vista se we shut off the engine & know it just turns over but wont start


Probably lost either spark or fuel to the engine. Try starting it with starting fluid into the intake. If nothing happens, check for spark on a spark plug wire- probably the ignition system. If it runs for a second or two with starting fluid, it is a fuel problem-check fuel pressure to see if the fuel pump is still working.

Wont start but fuel pump works n relays


Have you checked for spark? Also just because the fuel pump kicks on doesn't mean that it has enough pressure. It only operates within a small PSI window. Any check engine lights on?

Engine shuts down


The only way to know for sure is to hook a gauge to the rail and check the fuel pressure when it won't start.
Sitting for a few minutes and restarting is normally a sign of a relay or coil cooling off.
There should be a EEC relay that powers the dist module and ECM.
I know you said you have spark, but it could be something else
related.
Also, if you have spark at the right time and no fuel pressure, you should be able to use starting fluid to substitute.
I don't suppose you have dual tanks and the switching valve is the problem ?

My car doesn't start but the battery is fine. The engine fuses are fine. There is no fuel going into the engine. What could the problem be? I already replaced the fuel pump. my car is 96 Dodge grand...


put a funnel in the gas nozzle have someone turn ignition on to almost start, but don't. You should hear pump running before you start your van if you don't hear the pump you know you have a defective pump if you hear the pump purchase a fuel filter try that if not possibly could the relay not sure where its at but could finds out for you.good luck

2002 blazer crank but wont start


2 things that you have to check on no starts every time. Spark at spark plug and fuel. Turn key to run position and listen at gas tank for fuel pump to run you should hear a whining noise. This will only happen for 3 to 4 seconds then it will shut off until engine starts. You can turn key off then to run every 3 to 4 to listen for fuel pump. You may hear the relay click off in engine area even if pump does not run. Fuel pump failure is pretty common. If pump is running pull spark plug out or put a spare plug into spark plug wire and have someone crank engine set plug on engine and watch for spark. This will give you a starting point. Hope it helps.

Jeep won't start until a clicking sound comes from fuse box


The click you hear is the fuel pump relay. It gets its signal to energize from the PCM.If you have a faulty Crankshaft Position Sensor, the PCM will not work. Check for a bad fuel pump relay and also all of the other sensors: Camshaft Position Sensor, MAP Sensor, Idle air Control, Intake Air Sensor,etc.
