I would make sure that the pump is running all the time. Is it getting current?Try a jumper wire to the pump; Splice it into the positive lead .There are two wires at least to it and a separate for the gauge. I went through this whole thing to find out I had a frayed wire near the pump. I hope this helps you. Mark
try the pump on the frame there are 2 pumps high & low low is in tank
Answer:
Also check the interia switch. It may need reset. It is located on the passenger floor board, under the carpet next to the tranny hump.

Where is the fuel injection pressure regulator located on a 03 f350?
The fuel injector pressure regulator is located in the injector fuel pump. Most pressure regulators cannot be separated from the fuel injector pump.
I need Help on working on fuel problem on a 1998 s10 blazer it wont start and I have replaced everything the injector body the pressure regulator and im getting fuel up to the injector body not spray?
You may not have sufficient fuel pressure. The 2.2 should have 41 to 47 psi and the 4.3 should have 60 to 66 psi.
Does turning key on and off and back on immediately to gain pressure in fuel injector damage the starter?
No. Fuel pressure at the injector is regulated by the fuel pressure regulator.
What is set pressure?
the pressure we set for the injector and tested on machine
In a 1987 mercury topaz why would fuel make it to the injector but not through you have good pressure and power to injector?
MIght be the injector itself.
1989 jeep wrangler 2.5 good gas pressure to the throttle body but no spray?
probably a bad injector, check for pulse to the unit before replacing, could be another component if there is no pulse to the unit.
Why does gas get to the injector but wont come out?
The injector is probably clogged, or there isn't enough pressure from the fuel pump in the first place.
What is the detergent injector ratio for a sears pressure washer?
The detergent injector ratio for a Sears pressure washer varies, according to the type of brand. The ratio of some pressure washers is 12 to 1 while others are 7 to 1.
How do you get a pressure washer to siphon soap?
Pressure washers use an attachment called a chemical injector to siphon soap into the water stream. The chemical injector works based on the the physics principle known as the Venturi Effect. The Venturi Effect occurs when there is a restriction in a medium through which water or air is flowing. This restriction causes an increase of speed in the flow, but a drop in pressure. A chemical injector uses this drop in pressure to siphon chemicals or soap into the water stream. With a chemical injector, this drop in pressure is achieved by using a nozzle with a large opening. There are two main types of chemical injectors:Downstream injector- This type of chemical injector is placed on the outlet side of the pump. A special nozzle is used (as mentioned above) to decrease the pressure to that the chemical can be siphoned.Upstream injector- This type of chemical injector is placed on the inlet side of the pump to inject the chemical into the water before it enters the pump. This type of injector is also known as a "high pressure" injector because the chemical is pumped through the pressure washer, and is thus released at the high pressures with the water. This is the only type of chemical injector that you can use different nozzles with. Since the chemical is injected using the low pressure inlet hose (garden hose), you do not need a special nozzle to decrease the pressure on the outlet side. This type of chemical injector is usually not recommended, however, due to the fact that the chemical is circulated through the pump. This can cause seals, such as the pump's o-rings, to wear out faster.
On an 1990 S15 GMC is not getting fuel from the injector?
If it is just one injector, it is a bad injector or a problem in the wiring harness or connector for that injector. If it is all of the injectors, it could be a fuse, the entire injector harness, a broken loose or unplugged connector on the injector harness, or the fuel pump or fuel pressure regulator.
What are symptoms of low fuel pressure?
You'll notice a drop-off in your gas mileage, then a really rough idle. If the pressure is REALLY low, you may even get a stall when coming to a stop occasionally. Replacing the fuel pump ranks up there with getting a prostate exam. So, before taking on that challenge, consider replacing the fuel filter, running through a tank of GOOD fuel-injector cleaner, and attend church (yeah, replacing the pump is THAT bad!!!). Good luck!
Would the fuel injector pressure regulator cause a low idle?
NO.
