Fuel/Immobiliser issue????
Discussion
Im hoping somebody can point me in the right direction here. I have an 02 Tuscan and the other day immediately after refuelling the car simply refused to start, after the embarrassing episode of having to push my car off the forecourt during rush hour (plenty of amused spectators) The car did eventually turn over and I managed to get home without incident although as soon as I got home and turned the engine off it refused to restart again. I called the AA and after trying a few things the patrol guy removed the fuel pump fuse and the car billowed a load of white smoke and petrol due to the engine being flooded from all the attempted starts. The car ran again perfectly although now pulling away in first the car seems like its being starved of fuel and again as soon as the engine was switched off exactly the same again it simply refuses to start. Im no mechanic I simply love to drive my car and I dont wish to start replacing expensive parts (i.e FUEL PUMP) simply to find this is a loose connection or a faulty relay switch as so often seems to be the case with TVRs.
I had the no-start-when-hot problem as well. The car would start OK when cold, but if I stopped for fuel or if the car was warmed up, it sometimes would not start. Quite embarrassing, I agree...!
Apparently, its the starter motor on its way out. I had it changed and the problem was cured.
But I had no other issues like you do...

I dont believe it to be the starter motor as the car started no problem with the fuel pump fuse removed. I am of the firm belief that it is an electrical/immobiliser issue. But thanks for the response
Did you fill the tank to the brim? this can cause the symptoms you describe starting after filling up. Its a TVR thing don't ask me why, I never had the problem again as I don't fill her to the max (just until the pump clicks off) You flooded it as well trying to get it started which is easy to do. Two separate issues that are un-related.

Already learnt my lesson with the refuelling after filling it to the brim the first time I refuelled and kangarooed off the forecourt and for the next couple of litres. At first that is exactly what I thought it was even though I only topped up to about 45 litres well below the stated 55 litre capacity. Its very coincidental that it happened exactly when I refuelled but it has done it again after I have travelled about 30 miles or so and after the car has been stood for a couple of days so its not a cold/hot issue either. Ive got it in the garage today so hopefully they will find out what it is just hoped somebody would have had a similar issue and could have pointed me in the right direction so to speak.
It looks like its been sorted. The garage has informed me that the fuel pressure regulator switch is faulty. This is causing a surge of fuel every time the ignition is turned and thus causing the engine to flood. Hence why when the fuel pump fuse was removed and no extra fuel was getting pumped into the engine the car fired up and ran. Fingers crossed I will be picking it up tomorrow night after work and the sun will still be shining over the weekend
How can a surge of petrol flood a fuel injected engine ?
Doesn't sound right to me. The pressure regulator stops excessive fuel rail pressures at low engine speeds as I understand it.
When you say it doesnt re-start , does it crank OK, just not fire up? Does it "try" to start i.e. cough and splutter ? Or just nothing ?

Guys just for my own benifit, where is the fuel pump relay?
Get your head down in the drivers side footwell look up and you will see a fuse board with the relays, the fuel relay is the biggest one there it protrudes more than the others it can get warm to the touch.Gassing Station | Tuscan | Top of Page | What's New | My Stuff
