Car stalled in the middle of traffic. I think it may be a...

Hello, Welcome to Just Answer My name is \*\*\*\*\* \*\*\*\*\* I've been an automotive engineer since 1996 and together we're going to solve this issue. I understand that having your trusted vehicle let you down can be frustrating as it rarely occurs at a convenient time, however I will do my best to either help you make the repairs yourself or at least understand the issue so you know what is involved. is there any check engine or other fault light on the dash ? as if there is then using a scan tool to read these code or codes should be the next step as it will greatly speed up the diagnosis if there's no check engne light then this sounds like a lack of fuel and could be a lack of fuel pressure from the electrical pump at the tank. 1st thing to try is to remove the fuel filler cap and then flick the ignition on whilst listening for the brief ‘buzz’ of the pump If the connections to the pump are corroded or damaged, then the pump could stop at any time or could not be running at full speed. Check that its relay switches in and out and the relay contacts are clean and bright – replace the relay if in any doubt and do the same for the fuse, Ideally measure the pressure at the injector rail (should usually be around 3Bar / 45psi +) and if this is low check the pump as described and consider changing the fuel filter as if this partially blocked this too will reduce pressure. You can also get this issue with contaminated fuel , if there’s water or dirt in the tank then either the petrol floats on top of the water or the filter sock on the pump is choked up – so if the other things check out then I’d consider pulling out the fuel pump and cleaning the filter sock And one other thing to try is to loosen off the fuel filler cap, as there’s a 1 way valve built into the cap to let air into the tank and so prevent too great a vacuum from being created as the fuel leaves the tank to the engine If this helps, then replace the cap with a new item

check engine light is on.

OK, in a way thats good news as its a lead into the issue so teh next step is to plug in a scan tool and read the code even the cheap ones off Amazon for about $40 should the trick once you have a code then please let me know what it is
