The most likely problem is the fuel pump itself is shorting out,it will have to be replaced to repair the problem,it is in the fuel tank.

2004 pt cruiser keeps blowing fuel pump fuse,replaced fuel pump, no change.runs rough at idle and stalls,blows fp fuse,also replaced ign.coil,plug wires and plugs also changed relays


There are two fuses for the fuel pump relay. One fuse is load side of relay, that fuse also sends voltage to load side of asd relay, the asd relay sends voltage to several systems, two of which are the fuel injectors and ignition coil. I'm not telling you to replace, anything, but, you need to do some testing.
The other fuse goes to control side of relay, smaller amp fuse. I don't know the amp rating of the fuse that keeps blowing.
See that fuse, it supplies voltage to load side of fuel pump relay and also to asd relay.

12ht wont prime


filling the filters before installing will make priming go more quickly.
once the pump is primed crack open the fuse line at the injector while cranking until you have fuel pulsing out, close it then move on to the next injector.
keep doing this until the engine runs smoothly.
it may start running before all the injectors have been purged so keep clear of all moving parts and a fire extinguisher handy would be a good idea.

The fuel pump fuse keeps blowing in my 92 grand am


So it is the injector fuse, not the pump fuse? The injector circuit must have a short in it, or an injector may have a short and be bad. Have your injectors tested with a "resistance test"-they do not have to be removed for this.If injectors test out good, you need to inspect the injector harness for bad wiring. Maybe you missed some of the melted wires?

1997 GMC Sierra, I keep blowing the ECM 1 fuse, I replaced Fuel Pump relay and Fuel Filter. Does the ECM 1 Fuse Pump the Fuel Pump, also disconnected the Fiter turned on the key and no fuel.


ecm1 is injectors not fuel pump ecm-b is fuel pump its more likely to be a faulty relay for the injectors, it would be a similiar design to this
12900_oil_sending_unit_and_fuel_pump_circuit_80-yoo05im5qhid2i2poe1uh03c-5-0.gif this is for the fuel system, relay for the injector is nearly the same.

Fuse keeps blowing!


The fuel injection fuse should also power the injectors. If the fuse is blowing, I would think one of the injectors has shorted to ground.
Have you checked them ?

Fuel injector fuse is blown, keeps blowing. Engine turns but won't catch and start.


if the injector fuse is blown then the car won`t start as its not getting fuel into the motor to fire.if the fuse keeps blowing then you could have an injector/s that is drawing too much or the injector driver in the ecm may not be any good and needs replacing or a used ecm.it could be a short some where in the wiring for the injector system that is going to ground.

I have a 99 windstar fuel pump was replaced but it keeps blowing the 15amp fuse under the hood, it wants to start but fuse keeps blowing. any ideas?


If it is blowing the fuel pump fuse, then when replacing the fuel pump one of the wires are pinched. Check the wiring. Even if the fuel pump is bound up or something then it still would not blow the fuse. More than likely the hot wire to the pump is pinched and grounding out.

I HAVE A 1986 300ZX NON TURBO. IT CRANKS BUT APPEARS TO BE A FUEL ISSUE. HOW AND WHAT SHUD I CHECK TO SEE IF IT IS INJECTOR/FILTER OR PUMP PROBLEM.


First I would go ahead and change your fuel filter, I change mine every 50k miles. "Home remedy working with what you have" assuming the fuse and relay are good. Unplug the main wire from the main coil to keep the car from starting as we test the fuel pump and the pressure making sure is working properly. To check and see if you getting any fuel, One way is, under the hood locate the fuel filter, disconect the fuel line from your fuel filter, cover the end of the fuel line with a clothes over the hose and have a friend turn the ignition over couple of times and see if any fuel coming out of the line. Make sure you point the fuel line downward away from your face just in case, otherwise it will squirt and shoot fuel over you. Make sure you also have your finger over top of the hose so you can feel the pressure from the fuel pump. If it weak pressure replace the pump, keep in mine, its 1986 and that is an old fuel pump with high miles. Being 1986 Z car, I would say its the crank sensor is bad although it dont believe it has one but everything is built into the distibutor unit. If you getting good pressure than it could be your fuel regulator and no way of testing it, there are also cheap to replace or your fuel injectors is bad again all injectors cant go bad at the same time unless the car has been sitting in the storage for years. If one goes bad, its best to replace them all. I can see one or two injectors goes bad but your engine should still be running but run rough like missing firing. Every 3 to 4 month with my fill up I always use a can of fuel injectors cleaners add to my gas tank to keep problems free. I have 320k miles car and still have the original injectors although I filled and use 93 octane once a month just to keep everything running smooth. If you get a chance go to a junk yard a pull out couple of relays and see if that will do the trick, don't buy a new one, its stupidly expensive for a relay. If you doing your own repair I recommend you purchase Haynes auto repair book, great tools to have and instructions with pictures. keep me up to date and I will try to help as much as I can.... good luck.

My 2000 Tahoe will not crank unless you have over 1/4 tank of gas, last week it started dying while driving down the road, After 100 miles it died and then got more frequent and now dies after a mile. It...


Try replacing the fuel filter first and the primary fuel filter screen in the fuel pump may be dirty also. As for the the one in the gas tank which is a part of the fuel pump, your just going to have to keep the gas tank half full and add some fuel injector cleaner to the gas tank for the next feet fill ups. As for the fuel filter along the frame rail on the drivers side, they have a life of 30,000 miles or 1 year and needs to be replaced within those recommended intervals. Good luck and hope this helps, Note: the gas is what keeps the fuel pump cool, so low fuel in the gad tank will have the fuel pump run hotter causing it to fail prematurely
