Hi all, it’s my first time on the site, I was wondering if anyone could help? My girlfriend has inherited her grans old micra. It’s a 2001, k11, 1.4 sport. It’s got 20k on the clock so it’s not had a lot of use and has spent most of its life under a car port. It ran fine for a month or two but now cuts out after a few minutes running some times after a few seconds? It turns out it’s had an intermittent problem with this for years. So far all of the fuses, the cam and crank sensors have been replaced. This made no difference. Replacing the fuel cut out relay helped but hasn’t fixed the problem. Before the fuel cut out relay was replaced it got to the point were it wouldn’t start at all. I can hear the new fuel cut off relay trip, a moment or two later the engine cuts out. I bypassed the relay with a jumper wire. This had no effect, the engine still cuts out. When I try to restart the engine after this happens sometimes the engine management light doesn’t come on with the other ignition lights. If the engine management light comes on with the other ignition lights the engine will mostly restart. If it doesn’t, I have to pull the 15A fuse in front of the fuel cut off relay. This prompts the engine management light to come back on with the ignition, the engine then runs for a few seconds on the fuel still present and cuts out. I then replace the fuse, the engine management light comes back on with the other ignition lights and the engine starts. Unfortunately a few minutes later it cuts out again and I’m back to where I started. All the wires and connections seem fine. The two earths under the dash left/right are good. When connected to an OBD2 reader the MAF sensor showed a fault P0100. I replaced the MAF sensor with a £26 one from eBay. The fault remained. I then replaced the entire throttle body with a new one complete with all new Bosch sensors. The MAF error code was clear but the engine throttle response was very poor and the engine will still only run for a few seconds at best a minute or two. No noticeable improvement. I then changed the fuel filter. The fuel was at pressure, the new filter made no improvement. I then swooped the throttle body back to the original but swooped the ebay MAF for the Bosch one from the new throttle body. The throttle response and tick over are fine again but the engine still cuts out, no change there. It’s not an idle problem as it still cuts out at 3,000rpm. I’ve pretty much run out of things to replace! Does anyone have any other ideas? Thanks
