SOURCE: hard start

Its your fuel pump.I had the same plomblem not too long ago.I was spraying either in to start it.I have a 97 chevy truck witch requires 65 psi to start and 55 to run properly.You need to find out much psi you need to start it.You can probaly look in your manual or just make a few calls.My truck had 55 psi and it ran fine i just had to get it running first.Good luck.I wonder if that fuel pressure regulator was a waste of time like it was for me.

the fuel pressure if leaking could cause this the regulator is located under the intake plenum but you should smell gas .if you dont then most likely the pump is bad ,the pump will come on for 2 seconds when the key is on then go off it will not stay on with just the key on only when you crank it will it .so have your fuel pressure checked with a gauge.

I just replaced the fuel pressure regulator and now I am hearing a vibrating noise from the fuel line under the truck. What do you think the problem is.

My 2000 jimmy takes about 10 to 20 engine cranks in the morning when its cold out.when it starts its good the rest of the day. but its getting worse the amount of cranking the engine over in the morn


I'd use a fuel pressure gage, check fuel pressure, key on, engine off, first thing in the morning, 60--66 psi, spider fuel system. If you have the spider fuel stem, that system is noted for problems.
There is a service bulletin for cold start-up problems, caused by fuel poppet valves sticking. Once you get it started, it runs fine the rest of the day. The poppet cleaning procedure shows to be a shop procedure.

How to diagnose afaulty pressure regulator on the fuel rail of a 2005 ford escape


Check the pressure with a fuel pressure gauge connected to the test port on the regulator or on the fuel rail itself. There should be at least 30 psi on the rail with the engine running and the same without the engine running. If the pressure bleeds off when the engine is not running, the check valve in the regulator is leaking down which will make a first start in the morning difficult.

My car wontturn over in the morning. I changed to fuel pump and fuel filter. It cranks but wont turn over, then after a while it starts. What could be causing this


Fuel pressure regulator is a good place to look. look at the extra injector that enrichens the mixture on a cold engine too.

1991 chevy lumina wont start after sitting when you drive it


Just because you replaced the fuel pressure regulator does not mean it is working correctly; which is the most common cause of your problem. Hook up a fuel pressure guage and watch what happens when you are starting it cold - it should go up to about 47 PSI and once started it should read between 40-47 PSI, then when you turn the engine off: Does the pressure drop? There is a check valve built into the fuel pump also; that can be faulty and if the pressure is generally reading low and the check valve is bad- this can also create your problem. We have run into this before also; When the fuel pump is cold the internal pump seals are sealing great, but after a period of running time the pump seals lose sealing power and if you try to start it again it will be hard to start. The biggest thing with this situation is getting the fuel pressure readings at the following points of time:: Start-up, running cold, running at normal operating temp, engine off, engine re-start.

Vw polo will not start in morning , if i leave it for 15/20 mins will start and keep starting all day ,, then same thing next morning HELP


Tommorrow try turning the key on 2 or 3 times and then starting it. If it starts right away then the check valve in the tank is bad or the fuel pressure regulator on the fuel rail/engine is bad. Both will let the fuel run back in to the tank.

Your car is fuel injected and has a fuel pressure regulator valve that allows fuel to return to the tank, one sure sign that the valve is bad is that it allows all the fuel pressure to return to the tank so you must crank and crank which in truth is not what gets it going. You attempting to start it multiple times is turning the fuel pump on for @ 30 seconds. Untill you have the valve tested try turning the key to on, when the pump stops running (whirring or light buzzing sound) turn the key off and back on again. After a few times the pressure should be built up enough to start the engine.

My 1999 GMC Suburban is hard to start first thing in the morning. It has to turn over for a while before it starts, almost like it has to wait for the fuel to get to the engine. After the first time, it...


Yup!
The fuel pressure valve is stuck open and drains the fuel (via gravity) back to the tank.
Check the fuel pressure regulator / replace.

You might want to put a bottle of "complete fuel system" cleaner ($8 AutoZone) in the gas (not diesel) tank, next fill-up. It may do the trick in a couple of days.
