Long startup time from cold

[Anonymous]

Hi again,

When it was brand new, I could only here the starter roll once and the engine was running sweet. I changed the plugs and immediatly after that, I now hear the starter roll 3 ou 4 times. Suggestions?
When hot it's ok! The plugs are basic NGK with two pins.

Its cold and old.

3-4 turns is nothing.

On my scooter i used to verify the gap between the plug center and the pin. Is there not something like this?

I have similar problem, short after regular service. After couple hours of standing Bravo not start happily as use to be. Starting it immediately after stop, Bravo start as it has to. Does not meter hot or cold. In the garage, they check the pressure of the fuel pump (fuel sender unit) and found pressure lost after switch-off the key, what is not good. Fuel lines, under the car, were good but short pipe in the fuel sender unit has hole. This pipe is not spare part and mechanic replace it with rubber fuel hose and noted that this hose wouldn't last long because it is not for submersible applications.
Gates (belts and hoses) has hose for submersible applications Prod. No: 4219-05184, Part No: 27093 and I will buy it when Gates importer purchases it.

The fuel pressure will drop when you stop as the fuel pump stops. No pump, no pressure.

Well, I have 1.8GT Bravo. For that model pressure in the fuel supply line have to remain constant 60sec. I supposed, possibly wrong, that this is same on all engine models. After changing pipe with hole, I have seen that pressure remain when pump stops. Before repair, pressure drop immediately after pump stop.

 

[Tom]

You said a couple of hours in your first post, 60 seconds is a lot less than a couple of hours.

Tom, Fredo's post remind me to my experience with harder starting and I wrote my post as suggestion what he can check if checking plugs wouldn't solve problem. On my car, I have changed plugs in the first place.
I wrote “couple of hours” as my finding from regular car using. I didn't check what happened after 15 minutes, 30 minutes, and so on, and mechanic do right conclusion what to check first.

I wrote, “pressure lost after switch-off the key” too. That was a diagnostic finding.
Yes, without running pump, fuel system will lose pressure after a while, but not so fast.

What is fast? Tom, I don't want to argue.

Best regards, Misa.

Hi,

This answer is interesting but I cannot figure why it happened after service.
When you switch on ignition, you can hear the fuel pump pressuring the system. The system "should" be under pressure when the noise stop.
Anyway, is it easy to access this hose and can I check/repair it myself?

I used to have some major problems starting my 1.6
I changed the HT leads the plugs the coil pack and the fuel filter.
Now it starts fine.
I'd recommend a decent set of plugs for a start and change the HT leads
if that works you've cracked it if not try the coil pack

>This answer is interesting but I cannot figure why it happened after service.

-Just coincidence, I suppose.


>When you switch on ignition, you can hear the fuel pump pressuring the system. The system >"should" be under pressure when the noise stop.

-Yes, if you think about pump self-stop after a while, with ignition key on. With hole in the system, pressure wouldn't remain but pump didn't start agene self-alone.


>Anyway, is it easy to access this hose and can I check/repair it myself?

-That pipe is inside the fuel sender unit in the fuel tank. You need a special tool (wide, upside-down U leter shape) to dismantle the fuel sender unit from the fuel tank. Maybe is better way to go to the garage and let them to test the whole fuel system pressure with appropriate manometer.

when i stop my TD100 Brava you can here it keeps it pressurised for bout 30 seconds before switching itself off

MisaR, make up your mind on what the symptoms were.

First you say it was a hole in a pipe that was letting the pressure out too fast (although you said it was hard to start after several hours by when the pressure would have gone anyway)

Now you say that the pump was not restarting after presurising the system.

Sounds more like the fuel pump was at fault...

>MisaR, make up your mind on what the symptoms were.

-Symptoms were as I wrote in my first post (July 23 2005, 10:44 AM).


>First you say it was a hole in a pipe that was letting the pressure out too fast (although you said it was hard to start after several hours by when the pressure would have gone anyway)

-As I wrote earlier (July 24 2005, 7:39 AM), I didn't tray to start engine after 15 minutes or so.


>Now you say that the pump was not restarting after presurising the system.

-When car working in order and when you turn the key in the first position (engine not started), you can hear pump are working for a while and stop. Fredo wrote "The system "should" be under pressure when the noise stop." and I agree with that and add "With hole in the system, pressure wouldn't remain but pump didn't start agene self-alone." which means that without starting engine, just turn the key to the first position, pump stops after a while and wouldn't start agene without turning the key further (starting engine) or switching it completely off and turning it on agene.


>Sounds more like the fuel pump was at fault...

-After changing pipe with hole, two months ago, car is running well.
