Yes ... most factory fuel pumps run at 35lbs of pressure on fuel injected vehicles ... if the pressure is not enough then the injector relays arent sending enough fuel if any into the cylinder ... 1 way to check is to turn the key to the starting position after raising the hood of course ... look on the fuel rail there should be what looks like a valve stem. with the car turned on use a standard tire guage and apply same as testing air in a tire just make sure you are NOT smoking while trying this if the guage reads anything below 30lbs ... the fuel pump needs replaced. if the guage reads 30 or more ... check the injector relays

Yes your engine is fuel injected and is pressure sensetive so a weak fuel pump with low prerssure creats a real problem for the best performance of the vehicle

    the fuel pump is an electronic one located inside the tank itself you will have to drop tank in order to gain access to the pump there are hoses that disconnect from it and a electric connection plug. no diagram is needed for rep[lacing the pump

I have 1997 Cadillac Deville 4.6 v8 Northstar 32 valve it has 90 pounds fuel pressure an it should have 40 to 50 pounds why is the fuel pressure so high?

Fuel pressure regulator . plugged fuel return line .

With the ignition switch ON and the fuel pump running, the fuel pressure indicated by the fuel pressure gage should be 333-376 kPa (48-55 psi).
The Fuel Pressure Check determines if the fuel system is providing fuel pressure. The components involved include the fuel tank, sending unit, pump, pipes and hoses, pressure regulator, fuel rail, and injectors. Also checked is the electrical operation of the fuel pump relay. This chart requires J 34730-1A , Fuel Pressure Gauge J 37287 , Inlet and Return Fuel Line Shut-off Adapters.

1999 tahoe while driving it stalls we have to start it with starting fluid

Sounds like a fuel pump issue. Do you run the fuel tank below 1/3 of tank? That CAN overheat the pump if there's not enough fuel to cool the pump. It may be the fuel regulator, filter, or pump. There have been some noted issues with insufficient grounding of the fuel pump wiring as well as some pumps that just don't live long. If you have access to a fuel pressure gauge, check to make sure you have over 60 pounds of fuel pressure at the fuel rail under the hood.
As the fuel pump is submersed in the fuel tank, enough fuel to cover the pump is needed to adequately cool the pump. Running the tank low will eventually cause failure of the pump.

I replaced fuel pump on my 2001 s10 i only put 4 gals of gas in didnt fill it too much incase it had to come back off my question is how much gas needs b in it for it to prime it pump runs a few seconds...

This should be enough to do the job. If the pump is cutting out check your fuel pump relay in the power distribution box under the hood and the ignition switch for a short as well as the connections on the bump for proper installation. The pump should stay cycling to maintain pressure on the line at the proper level. You also want to check the fuel pressure sensor to make sure it is working properly.

On first crank fuel pump doesnt hold pressure and has to be cranked on for several seconds

sounds like its not working properly, the fuel pump pumps or it does't, then goes to regulator this is where pressure is adjusted. check fuel pressure with gauge, sometimes even new fuel pumps don't pump enough fuel. most fuel injected cars have over 50 pounds pressure.

Put seafoam into gas tank, replaced ignition coil wire only, won't start acts like choke stuck, fires but won't stay running

3 words- "Fuel Pump Failure"

Sea Foam is a bad idea- its a good temporary fix but the cons outway the pro's-

When you first start your vehicle the pump has enough pressure to fire but it doesnt have enough ump to keep the proper pressure level and the engine dies- anything after 1995 has 1 to 2 pound variance of pressure anything less than that and the fuel pressure regulator fails to operate properly

Doesn't start only turns over

Sometimes a defective Fuel Pump will run and operate as normal and give you the correct pressures before start up, but can't work fast enough to keep up with the demands of a starting, or running engine. Engine's take a high demand on fuel for startup, its a short period, but a high demand nevertheless.

My opinion is that your Fuel Pump is faulty, Not completely broken, just unable to keep up with fuel demands. Try replacing your Fuel Pump, and while you're at it, be sure to check the lines in the Gas Tank itself for frays, holes, or rips. As that can actually cause the problem too, but is VERY easy to over-look it, as fuel can squirt out of a pinhole at 60psi
