So, my question is about the vehicle listed above. It's my friend's car and it's currently in a cranking no start condition. The car has been experiencing a certain problem since she bought it where it loses power and eventually shuts off when driving on the freeway for long periods of time. Many parts have been replaced including the MAF sensor and ignition coil. We were thinking it could be a clogged fuel filter because we noticed that there is a lot of vibration in the engine (visibly) when looking under the hood while the car is running. The car has also thrown several misfire codes over time. We had a really hard time trying to figure out where the fuel filter was on this car, and finally came to the conclusion that it must be inside the sending unit/ just the sock itself which is attached to the fuel pump. We took the fuel pump out to look at it and then put it back in and now the car is cranking but not starting. We triple checked all the wiring connections on the fuel pump and nothing seemed at all different from when we took it out. Did we somehow trigger the immobilizer system by doing this? The fuel pump is audibly running so we know it's working but the car is just cranking and only turns over with starting fluid. Any input on what could have gone wrong when we reinstalled the fuel pump that's causing this no fuel condition?
Thank you!
