Not starting - oil light flashing

[daverave]

Managed to start the car (LCR 05 225 Mk1) this morning just to shift it out of the drive. Turned engine off, then the engine wouldn't restart! The red oil light started flashing and beeped three times.

I've checked the oil level and it was very low. So I've topped it up but still the engine will not start. I'm also getting the yellow engine light and yellow EPC light on before I turn the ignition - but I think this is normal?

Just to clarify, the Engine (diagnostics) yellow light goes off once trying to start. The only lights which stay on are battery and handbrake. The oil light flashes and beeps three times.

I did change the battery last week ... would that have anything to do with it?

When's the last time it was started before this morning?

 

[daverave]

Before this morning, it was last started yesterday evening.

Check fuse 28 I think,inside of car, it's the fuel pump

 

[daverave]

Just checked fuse 28 and it's fine.

Just tried starting again, starters motor turing over well but engine still not starting. But this time I'm not getting the red flashing oil light!

Doesn't the red flashing oil light mean low oil pressure?

 

[Bigjohn84]

Yeh but if your not getting it now then it may be fine, crank sensor could be a few thinks mate, could be the pressure try get a jump start meaning a push and see if it starts then if it does see if there's any lights on the dash, get it parked up first then turn it of and then try start it.

By crank sensor do you mean the engine/diagnostics warning light? It only came on for a second whilst trying to start up - Is this normal?

No the crank sensor is the one of the main sensors on the engine itself mate. If it fails then the car won't start. You need to get it plugged in to a code reader really buddy. Thats the only way to be sure.

If the engine is turning over ok, then i think you can rule out any issues with the oil. That wouldn't cause it not to start. The oil light does mean low pressure, but that could well be because it;s turning on the starter motor without starting. Like big john says, i would guess at crank sensor or fuel pump issue, either the pump itself or more likely the fuel pump relay under the dash. When you open the drivers door, can you hear the fuel pump prime itself? If not then the fuel pump relay would be where i would start mate.

Which relay is which? http://www.seatcupra.net/forums/showthread.php?t=278911&highlight=wiper+relay&page=2

Just opened the drivers door - couldn't hear anything! But can't say I've noticed a noise in the past.

I'll have a go at changing the relay.

p.s. If I run VCDS lite (I have a cable but can download the software), is this likely to show up a fault code which might help the diagnosis?

 

[Bigjohn84]

Worth a try but as its not the full software it may not

AmD Stage 1 Map, Forge 007 DV, CDA Induction Kit, GT80 Milltek Sports Cat Back.

Only fault code I get is 18010 P1602 Power Supply (B+) Terminal 30 Low Voltage. I did disconnect the battery for minute today just to see if it helped with the oil light problem. I guess that would have caused the Power supply fault code.

Yeah most likely that's what it was, thats a common code with a flat or disconnected battery.

If you can't hear the fuel pump and you have no codes then i can't see it can be much else mate. If you take the lower dash off, then you should be able to hear and feel it clicking if it's working. Also if you want to check further than you can disconnect the fuel pump and see if you have any voltage going to the connector.

Crank sensor or similar should definitely throw a code. There are no fault codes for the fuel pump relay, so again it would make me suspect it might be that.

i assume you started the car, moved it a very short distance then turned off in a very short period of time?

I would say:

remove fuel pump fuse. turn car over for 15 seconds or so.
ignition off.
replace fuel pump fuse.
turn ignition on, wait 10 seconds, then try restarting.

RE the red light and bleeps. - can you confirm what the red light looks like and where its located? sure its not the coolant level light? (is car on a slope?)

see link, is the light number 2? (coolant) or an oil can shape in the centre square?

Yes to above questions.

I'll try this! I'm not clued up enough to think why it may work or why you've suggested it!

give it a go and hopefully it works. if it does i will try to explain, but if it doesnt then i wont waste your time

No slope. The red light looks like an oil can! It's on the right of the handbrake light.

Just tried!

Didn't work!
