Fuel cut off switch location


The Vehicle Control Module (VCM) electronically cuts off fuel to injectors when engine speed exceeds 5500 RPM . You should hear fuel relay click on firewall when key is turned on . Esay way to check fuel pressure without proper gauges is to diconnect fuel supply line at engine and cycle key , Have plenty of rags around fuel line .

I have no fuel pressure where do i start to find the problem


Okay, hey, the fuel pump circuit. With key on, the pump should turn on for about two seconds to put pressure in the line and in the fuel rail on the engine, where the fuel injectors are. When the engine is cranking, the pump is turned on again by the vcm (Vehicle Control Module-the engine computer) signaling the fuel pump relay, just as it did with key on. After the engine is running, the pump is kept on, usually by the oil pressure switch.
No fuel pressure? Then the pump is not turning on, or the fuel filter is completely blocked-which is rare.


You can start at the Underhood Fuse Block. Here is found the fuel pump relay and the fuse for the pump. The fuse is designated ECM-B Fuse and it's 20 amp. If the fuse is good, put your finger on the fuel pump relay. Now have a helper turn the key to on, not start. If the circuit is good to this point, you should feel movement- a slight click. If you feel nothing, and the fuse is good, then the VCM is not sending a signal to the relay OR there is a wiring problem from one side of the relay to ground. If no click or movement under your finger-you will need professional help to diagnose further-checking of the signal from VCM and/or checking the ground wire for that side of the relay.
If you definitely feel a click at the pump relay, and the fuse is good, the power to the pump is sent out from there on a gray wire. Get under the vehicle at the rear and find the electrical connector for the gas tank, and pull it apart. Now you need a test light or voltmeter to check for power on the gray wire in the connector. You might miss the two second signal with key on, so have your helper hold the key in start. While the engine is cranking, the gray wire should have power-battery voltage. If it does not, big problem: possibly a broken wire or short from pump relay to there at the gas tank.

If the gray wire has power with engine cranking, you're almost home: Either the pump has definitely failed OR the ground for the fuel pump is bad. The ground wire is black and it shares the same ground point as your rear exterior lights, so if the lights work, the ground can be assumed to be good also for the fuel pump. And then you need a new fuel pump. But check the gas tank connector carefully for any sign of corrosion, loose terminals, anything like that amiss. Not likely, but check anyway-you don't want to put in a new pump and then find a loose connection! Good luck.

ASK SEARCH HOMEANSWERPROFILESIGN IN Problem with 1988 Dodge Ramcharger 1988 dodge ramcharger 5.2 liter. no fire or fuel.replaced computer and coil still no fire or fuel.jumped 12volts from battery to...


Without a voltmeter and a wiring diagram, you're in a bit of a fix. But I would be wondering why the ignition switch isn't sending power to the coil primary positive terminal, and why it isn't causing the fuel pump to be turned on, too.
Is your check engine light on with key on? The computer should sense ignition is on and briefly turn on the fuel pump through the fuel pump relay, on just long enough to pressurize the fuel line to the injector. But no fuel or fire-you'd better start by checking if the ignition switch has power in and power out, and work your way to the coil.

Ive got a 1997 cavalier it will start but quickly dies out ive got fire to my plugs and fuel to the injectures ive just replaced the ignition switch is there somkind of a security


You need a new fuel pump relay. The engine fires up and runs off the oil pressure switch untill the oil pressure PSI is reached at normal operating conditions. When the oil pressure reaches its operating PSI the PCM or engines computer will shut off that circuit and turns on the fuel pump relay to run the fuel pump untill you shut the engine off

Car turns over fine just won't fire? where should i start? checked all plug wires and car does have gas, I am broke and without car, any help would be great.


check the ignition module fuse.if fuse is good.have car scanned to look for ignition control module fault codes or crankshaft sensor fault codes.by using or have somebody with diagnostic scanner to check for codes this way you wont spend extra money guessing.

My 98 dakota wont fire


Check your Automatic Shutdown Relay in your fuse and relay box under the hood by the battery. The power supplied to the fuel pump, ignition coil, fuel injectors,  and parts of the power module is controlled by the logic module through the Automatic Shutdown Relay (ASD); the idea is to shut off fuel pressure and the ignition systems when the key is turned off to prevent fires, dieseling, and other problems.
The ASD relay is closed (allowing power to flow through it) when the ignition is first turned on. If the signal from the ignition reference is lost while the engine is running, the logic module cuts power to the ASD, which in turn removes power from the fuel pump, ignition coil, injectors and those parts of the power module.  This causes the engine to shut down.

The logic module monitors the relay driver.  If it senses that the relay driver is not responding correctly it will trigger a code. If the logic module does not sense an absence of current when the circuit is open, or 12 volts DC when the circuit is closed, it knows that the circuit is open or shorted, and triggers code 42. Failure of the automatic shutdown relay is often shown as inexplicable stalling or refusal to start. Good luck and hope this helps lead you in the right direction. Hint: The ASD can be triggered by a broken wire or short in another place, e.g. the fuel pump.

No start turns over good has good spark


easy way to check if its getting gas is to take off the breather hose and pour some gas in then put it back on before you try to start it if it starts or even try's too then its fuel pump

No power to fuel pump, relay is good, engine cranks over but won't start.


You need to follow a detailed troubleshooting procedure in a repair manual.
Check for spark plug fire during cranking after it dies.
No spark = ignition problem= computer will not fire injectors, and possibly cut out pump also.
Good spark = pump wonky, or power to pump system.
Also, other quick tests... when the thing dies, and then you crank,
1) Thump the fuel pump in the tank, if you can. A bad fuel pump might start up again.
2) Shoot some ether carb cleaner in the TB. If it only fires off the ether, the ignition system is no longer suspect.
