Well I've been struggling to find the problem with my poor teener for the past couple of days (again). It all started a few days ago as I was leaving the girlfriends house. It idles completely fine (lil high when cold) and runs consistently but as I drive off she has no power to speak of and begins a series of small backfires with an occasional large one.
Well I diagnosed it this morning, timing is dead on, all plugs are gapped perfectly as well as the clean points, and all injectors are squirting fuel. Has anyone had an experience close to If not exactly like this??? (IMG:style_emoticons/default/WTF.gif) |

Aar is just fine however I'm curious about the CHTS The fuel pump out of the blue refused to work this morning despite the relay being fine and I had to jump it off the coil to test the injectors. If the CHTS failed would that cut out the fuel pump?

If the CHTS failed would that cut out the fuel pump? I would have to say this tells me there is an issue with the fuel pump or the circuit that controls it being intermittent. The pump should run a second or two when you first turn the key on. After the engine starts the pump should continue to run. To see if the problem is with the CHT after the warm up and while you are in the failure......disconnect the chts from it's plug connect a test lead to the plug (NOT THE CHT) and connect the other end to the battery negative or a known good ground...this will tell the brain the engine is warmed up even it the CHTS won't. |
