Try resetting the PCM/ECM by taking off your battery terminals. Best to leave them off overnight. The pcm controls the ASD/Fuel pump and injectors circuit.

I cant find the fuse for the fuel pump on my 1990 Plymouth Voyager. It is NOT on the fuse block on the firewall. I cant find any fuses under the hood.


The fuel pump has no fuse, it is power as described below.
The two main fuel pump power feeds involve the ASD (Auto Shut-down Relay) which disables the fuel pump, fuel injectors, ignition coil and Oxygen sensor after the loss of a signal from the distributer. The direct power circuit for the pump travels through the relay from a white fusible link which is located under the hood on the left fender panel, along with the ASD relay. The other power feed for the ASD comes from fuse #13 in the fuse block. There's a lot more involved in the operation and troubleshooting of these circuits. So please make sure your diagnosis is correct before replacing the fuel pump, and yes, you do have to remove the fuel tank

No power to fuelpump or coil or coil driver so I ran a jumper wire and fuelpump and all started working what is causing no power


The common component to the coil and fuel pump is the ASD relay. The ASD (auto shutdown relay) is activated from the (ECM) engine control module by the ignition key, but in the event of a roll over or crash the ASD relay kills power to the engine and fuel.
26111978-lkayiuev2pawqft0guju1hyb-3-0.gif Above is a typical under hood power distribution. I will usually look for a identical relay and swap it with the ASD relay and see if it corrects the problem. If this is the circuit then the key switch and safety circuits need to be checked.

Where is the kill switch located at on a 2001 Plymouth Neon?


Doesn't have a kill switch , check ASD relay in the under hood fuse/relay box . Or fuel pump relay . Does your vehicle have spark at spark plugs ? Try spraying some carburetor cleaner into the throttle plate an see if it try's to start. The ASD relay powers the injectors an ignition coils .

No power to fuel pump 1999 jeep wrangler


do you know how it really works? most don't
the PCM controls the pump and the ASD relay is related.
all fuses good. in all fuse boxes.
car dont start , is that it, why not say
or starts for 3 seconds and dies, (ASD does that)
why not post the symptoms and ask for real help, not this guessing game.??????
ok ill pretend, no start
so is the ASD closing at all? cranking?? yes/no
if no bad news. or fuse blow, ask why.?
yes, but the relay drops out. well bingo.
the relay killed the pump power, on PURPOSE by DESIGN.
that is how it works. to stop CRASH and BURN as seen on TV and all movies, (it seems)

so why does the ASD drop out, well that too is easy and is
fully covered in the FSM.
but is listed here, in short, facts page.

is the IMMO faulting? SKIM?
my wrangler has a stealth IMMO lamp, so the creeps that steal cars
wont know what the red lamp glowing means (no ICON !)
do you? see operators guide under how to start a car and read said lamps.
8 ways, or less. to kill spark , fuel, and all.

Re: 1993 Dodge Dakota, where might I find the fuel pump reset button or inertia switch? Thank you.


  • You have an Automatic Shut Down Relay or "ASD Relay" not so much a "switch." The ASD relay inside the power distribution center which is under the hood on the left corner of the engine compartment. Under the lid is a legend that will pinpoint it's location in said box. I would look at this if your having problems with the fuel pump. Should you need to replace the pump the tank must be dropped for this vehicle.

No power to fuel pump


Try looking at the fuse under the hood make sure your getting 12 volts at fuse.If fuse is good but no power try checking the fuel pump relay. you can switch the relay with another system that you know works. Lastly Check you Auto Shutdown Relay (ASD). If there has been an accident this relay will kill your fuel pump power. good luck.

Where is the emergency fuel cut off switch located?


The neon don't have one, check the fuse and relay's. The fuel pump is also controlled by the Auto Shut down relay (ASD). 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 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. Good luck and hope this helps.
