![]() I was curious as to the possibility that there is corrosion in one or both of these connections. I tried to gently remove one of the two electrical wires at the fuel pump but was not able to get it gently off while trying to push in the small tab. We were wondering if the initial fuel delivery during a start was not occurring which was addressed by spraying starter fluid into the intake. My neighbor and I then postulated for a little while and I wiggled the two wires leading into the fuel pump and also opened the box next to the engine control (the unit that has cooling fins on it) and moved the connectors around in there a little, looking for anything loose. ![]() This was my same finding a couple of weeks ago. I then sprayed starter fluid into the intake, with the air filter removed, and the engine then proceeded to start. Next, the boat would not start with numerous prolonged attempts. However, I did remove the distributor cap and the rotor to inspect how to replace the coil, but stopped there and simply reinstalled the rotor and distributor cap as is. In other words, I did not replace any parts since a a couple of weeks ago. Yesterday, I attempted to start the boat (with my fake lake hose and bucket) mostly as it was since I last worked on it. I am now tending to agree that it is a fuel problem with an electrical (not directly ignition) problem associated. Do I have to remove the entire distributor assembly and go from the bottom up? It is a round cover which can be rotated back forth slightly within two slots vs pins, but I do not know the trick to get this round cover off. ![]() Not sure how to remove the next piece under the rotor to enable further disassembly to facilitate replacement of the coil. It has been a few years since any maintenance was done in this area, so I am just being proactive in replacing the cheaper parts that are easy to replace before going to the boat shop. Ordered new spark plug wires and a new coil. After buttoning distributor back up, the engine started, but then shortly died. Cleaned up corrosion underneath the rotor but not 100%. However, after shutting down back at the dock, again, the engine would not start on its own but would with starter fluid. With engine running, I then motored up and down the lake at Idle and high speed and it would run great. Sprayed starter fluid in the intake and engine fires right up. Engine will crank and crank with the starter but will not fire. 1994 Malibu Echelon 454 Magnum EFI, Fail to Start Troubleshooting and Distributor DisassemblyĮngine ran super all summer, but on what turned out to be our last ski day in October, the engine would not start after two fun ski runs on the lake.
