If you have recently worked on the vehicle before this problem, maybe ran out of gas and tried cranking it before u realized it. Chevrolet has a safety that shuts the fuel pump off to keep from overloading the intake with fuel. It also kills the fire too.

SOURCE: MY 01 Nissan Altima does not want to start.

Sounds like either the fuel pressure regulator or a clogged fuel filter.

SOURCE: on my 1994 plymouth voyager the 3 wire harness to fuel pump (blue wire) doesn't have 12 volts; should it? fuel pump quit then worked once when hot-wired with 12 volts. fuse and relay is good.

The wire should not be hot until the relay is triggered. The relay does not get triggered until the ignition key is turned on. It will run for 3-5 seconds or until the system pressure it at max.

SOURCE: 90 k1500 tbi no fuel from injectors

from the sounds of it its going to be one of 3 things 1) the injector is bad or 2) there is no power getting to the injector 3) bad relay switch.

1) to find out if the injector is good. pull the injector out and with some wire ground one side and touch the other side to your battery, every time you tap the wire to the bat you should here the injector click..

2) if injector is good get a test light and test to see if power is coming out of the wires that go to injector( on some vehicles you have to have the motor turning over befor power is sent through wire, so have someone turn the key while you check the wires with test light)

92 volvo 960 no injector pulse how to fix and no power to the fuse block for 30 & 31 fuses for fuel system


check your PGMFI (Fuel Injection Main Relay) if it's good then check the Fuel Pump for power with a probe tester. what do fuses 30 & 31 operate? maybe there is a short and maybe it has to do with those 2 fuse lines working against each other or maybe they are bumping heads with the injectors electrical wiring. my first advice is to check the fuel injection main relay and the fuel pump first.

Car is turning over but not getting fuel ideas anyone thanks


There is not much information for a good answer.
  1. Fuel filter clogged
  2. fuel pump not working [fuse,bad pump,broken wire etc]
  3. computer not telling the pump or injectors to work [should set a code]
  4. dirty injectors

S10 fuel injectors


Try a strong solution of Sta-bil that is a brand name sludge and varnish remover, Mix a strong mix up in the tank. Crank engine and see if it will start. If not, crank several times for about 10 seconds. Let sit overnight and try again. It seems as though your injectors are plugged. So try this. It is an awesome product.

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 believe my fuel pump went bad, I was driving down the road and the truck seemed like it was losing fuel. After it died i couldn't ever get it to start again. I bought a "used" pump from...


a locked up fuel pump would blow the fuse. also check at the fuel rail to see if the pump is working. it may have been a clogged line that burned up the first pump which in-turn burned the fuse.

and if there is/was a clog then it probably clogged the injectors as well, if fuel is making it to the injectors then you might try running a high quality fuel system / injector cleaner. I hope this helps.

good luck

No fuel to injectors why


Here are some troubleshooting ideas--let me know if you have more questions.
In most modern cars, the fuel pump is inside the gas tank and is also usually sold with the fuel gage sending unit--an expensive and laborious R&R job. If the pump is working, you should hear it at least momentarily when the key is turned to the "on" position. If the pump is not working, the cause could be a fuse, a relay, an accident "kill" switch that needs resetting, or the pump itself. You'll want to rule out all of the inexpensive possibilities first. Use your owners manual (you can often find these online if you don't have the original) to locate the applicable fuse, relay, and/or cutoff switch. To check the relay and ignition switch, follow precedures at http://www.fixya.com/cars/r6022358-relay_check. You can also check for voltage at the pump connector with a test light.
Assuming your pump works, fuel still needs to get to the engine. A clogged filter will certainly limit fuel flow, but will rarely prevent a car from starting. That said, filter replacement is an inexpensive bit of maintenance. Most likely cause of fuel not getting to the engine when the pump is working is the fuel injection system (not an issue for carbureted engines). Injection systems are beyond the scope of this tip, but there are a couple things you can check. Many anti-theft systems cut off the injectors when activated. If you have such a system, make sure your anti-theft system has not been activated. Also, the injectors require a certain level of fuel pressure. Though your pump may be working, it may not be producing pressure. If possible, have your fuel pressure checked or borrow the appropriate tool to test the pressure. Always check pressure at the fuel rail, as some designs include a separate regulator that is typically in the line in the engine compartment.

1993 s10 2.8 tbi the fuel pump fails to pressurize when the key is tunred on, and i have to fuel injector pulse. when a jumper wire is attached i can pressurize the pump but i still have no injector pulse.


There needs to be 60 PSI of fuel pressure in the system to have the fuel injectors to work. There is also a fuel pump relay on the fire wall just left to the brake booster, There is two relays there, i just can not remember which relay is which but try switching the relays with one another. Also check the fuses to the fuel pump and ECM, and the fuel pressure from the shredder valve. Good luck and keep me posted, not a bad Idea to also replace the fuel filter, and that is located at the inside frame rail under the drivers side.
