Ran out of petrol . . . now car wont run

Recommended Posts

Went out in the car before Christmas (a rareity for me these days) pulled up at PC World, parked and went shopping. Came back to the car twenty minutes later to find the damn thing would not start. Guessing I'd run out of petrol (it has been so long since I last put some in) I went over to Tescos, bought a can and put a fivers worth in.

 

The fuel pumps are running and the engine does fire, but needs constant right foot pumping to keep the car spluttering before dying its death.

 

Called the AA guy out, who after two more petrol cans (because he guessed she might be a thirsty one!!) and still no joy of keeping her running, was taken home on the back of a low loader with the advice that she might need more fuel, or the carb/injectors are blocked with crap.

 

Tried turning her over for the first time since today and now have a flat battery. Whilst the car is on charge I was wondering if you guys had some simple advice to try before getting ridiculously ripped off by a local (dont know anything about cars unless its a metro) garage.

 

A neighbour has suggested redex in the petrol to try and clear the injectors, but fear this may be far too simple and uneffective.

 

It may of course be a non-fuel related problem, but the syptoms to me sound like petrol, turning over, starting, then spluttering like it doesnt have enough fuel getting in.

 

Any advice greatly appreciated.

hmmm maybe soiled plugs? I had the same problem but mine was down to an argument between my aftermarket ECU which controlled fuel and a bolted on fuel controller.

 

Have you checked the plugs?

No not yet - and I hear they're a bit of a bugger to get to?

I don't see how a car would run out of petrol while being parked.

 

And what's with the AA guy putting more and more petrol in it? If Sarjo had already put £5 in it how is putting more in gonna help it start?

 

I think I was lucky to get to my location Jake before running out of - and I do hope its just a petrol issue.

Ive had the same problem.

Was almost out of petrol, put 20 quids worth in. after leaving it over night it too kages to start, then after a couple of days it just refused to start. Its been at Envy for the last 7 week. You wont believe how sick i am. They seem to have narrowed it down to injectors sticking open,(well we hope).

Goog luck with it mate.

I agree quite possible imo, if your running on empty think of the shite acumalated over the years in the bottom of your fuel tank sucked up into the filter as it saerches for fuel

 

Would you get this in the supra? doesn't it have a plastic fuel tank? I thought the accumulation of gunk thing was mostly from old metal tanks suffering corrosion??

Hows the fuel pressure? (with +B & FP diag ports bridged, not with it idling)

 

Fuel filter is the 1st thing to check with a starting issue after running out of fuel.

 

Fuel pressure looks good omer, one of the first things I checked. Where's the fuel filter then? :rolleyes:

Happy New Year and belated Christmas Greeting - also to you Pysmon

 

Plugs are not that bad Jo -read the guide on here cos you may need the two vac hoses under the plug cover /tricky bits are the coil pack clips so read that as well. Dont really know about sticking injector -would one of the fuel additives help ? -SOMEONE more tech comment please!!

 

Geez youre always in the shit girl !

Try disconecting the fuel filter on the engine side and turn the car over and get someone to turn the car over and check the flow through the filter failing that I would definatly get your injectors flow tested. Even though I had the same problem I found the car to be overfueling, injectors stuck open we think.

If the fuel pressure is good and it's measured at the rail (I assume an aftermarket sensor and gauge?) then the fuel filter is fine because if it's blocked the rail pressure would fall off.

 

You can pull a spark plug and use it to test all your coil packs by sparking it off against the cam cover, and eliminate the spark side of things as a problem.

Bringing this back to life . . .

 

Eventually got a good enough day to work on the car yesterday!!

 

As the car is so low, thought I'd check the fuel was getting to the engine first before raising her up to get to the fuel filter.

 

When I opened the bonnet I found that my fuel pressure was zero so thought ok, fuel filter. Removed a hose from just before the fuel pressure guage and hey presto there was fuel. The fpg sits on a valve type thing? What is that? I tried to blow through it but couldnt get air to pass through so guessing no chance of petrol getting through? There was a screw on the top which I undid and tried again. This time air passed through lovely???

 

Connected it all back together and turned car over. Still same problem, turning over, trying to start but no joy.

 

Removed the first spark plug and it was quite wet. Unfortunately light left me so am going to take them all out today, dry them out and clean them up.

 

If it wont start then, I think I'm stuck.
