NEW PUMP 41FUEL PSI AND DONT START

2001 S-10 4X4 4.3 NEW PUMP 41 FUEL PSI AND DONT START

  • mechanic144 May 11, 2010

    i beleive the s10 and s10 body style blazer required something like 65 psi of fuel pressure to start and at idle it would come down to the 45 psi mark...of course when you step on it, then the pressure goes up again. If the fuel pump is new, try to replace the fuel filter as well..that should be standard practice anyway...if that still does not help then test the fuel pressure regulator for output...and if not in specs, then replace...but have thought of checking for spark?

Are you one of those people who TOP OFF the tank when filling up?

When the EVAP recovery system soak with few ounce of gasoline......the trap vapor will take few days escape.

EVAP system is design to handle fuel vapor. Few ounce of gasoline can damage the fuel vapor recovery relay and decrease the service live of the recovery lines.

=========

You can accelerate the process by locating the charcoal canister (near the nose of the car and same side as your gas filler door)

MOVE the car to outdoor.

Disconnect the EVAP line and let it air out by itself.

DO NOT introduce any heat source or fan to speed up the process.

Reconnect this EVAP hose and use a small amount of starting fluid at the intake manifold.


Please post more information by Clicking on the comment link.

I will follow up.

Could there b a secoundary fuel pump between filter and fuel rail 99 ford ranger from alaska


No, if you are getting no gas make sure the pump is pumping to the right psi and you have a new fuel filter.

I have seen injections foul till they dont fire any longer, you may want to start with the pump and work forward.

Dodge2500two new fuel pumps will not prime up


Definitely start w electrical, go to fuel psi at proper locations & make sure PSI is not bleeding down after ignition is off If so you found the main problem. Now find out where it's losing PSI to. (leak, regulator, injector etc )

Fuel pump without enough psi. suggestions??


I am sorry to say that if the old pump was putting out 40psi then the pressure switch will need the same psi from the new pump.
With the psi les then what the computer knows the engine needs it will not allow it to start and run.

Just because you hear the fuel pump running doesn't mean the fuel pressure is correct, put a fuel pressure gauge on the car, 41-47 PSI (Pounds per Square Inch)Position the ignition switch and the A/C system in theoff position. Install a fuel pressure gauge to the vehicles fuel rail or fuel pressure test port.Confirm that no leaks are present, and visually verify the PSI reading on the gauge with the ignition in the on position.

Got a 1999 gmc jimmy. Wether it is cold outside or warm my truck has difficulty starting when the truck is cold. Got new plugs wires and distributor. Fuel pump is working fine. Once it is running there is...


Common problem with these is a fuel drainback. Use a fuel pump pressure tester, start the engine, If it's multi-port fuel injection the psi should be 50psi+. If 50psi, turn off engine and notice psi drop. If fuel pressure drops off to 10 or 5 psi, try to start engine and watch for a jump in fuel pump pressure. If pressure jumps to 50psi and the engine won't start, then I would suspect a good working fuel pump, if not a jump to 50 psi, I would say bad fuel pump. Good luck, Gary

Engine cranks but doesnt run


It almost sound like a bad coolant temperature sensor, but that is just a shot in the dark. I did have a 1995 LeBaron that had the same problem, and it had a bad coolant sensor. Is the check engine light on? Are you getting spark when it cranks but won't run? The fuel pressure itself, may have something to do with it, and with fuel pumps, they have a PSI specification, but there is also a volume of fuel amount, such as 1 pint in 15 seconds, I'm not sure what that amount is for you vehicle, but that maybe something to consider. I'd check for any vacuum leaks too.

Went to a store came back out would not start but strong battery,im tinking fuel pump dont know alot about car only had it a week


stand outside your van,reach in the window and turn your key over,but not to the start position. you should hear a whirring sound from the rear of the van and it should last about 2-3 sec. this will be your fuel pump powering up. if you dont hear it,then you have a bad fuel pump. Dodge Caravans from 96-01 are VERY bad about eating fuel pumps. if the pump is fine,have someone try to start it while you look under hood and see if injectors are spraying fuel. if the pump is good,and you have no spray from the injector,then you have a clogged fuel filter which will need replaced.

Car wont start


check your fuel pressure it should be 35 psi .fuel pump relays dont go out but check all fuses with test light there is a fuel injector fuse but most likely problem is your fuel pump!

Fuel presure dodge diesel ?


all i can tell you is that as long as you dont go below 4 psi you should not starve injection pump, this is a minimum psi though., 10-13 psi is average on my 2002 at service port.

1997 tahoe wont start


it is not the regulator if it has 40 lbs of pressure try to pinch off the return line and if pressure drops quickly it is either the check valve in the pump or the rubber seal between the pump and the sending unit
