Well - the fuel pump isn't getting power. I rigged it up to a hose, and got nothing... so I ran it outside the tank, and nothing. (with key on) I did hook it direct to power, and it runs like mad - so it's not the pump itself. (IMG: http://www.adamanthony.net/mitsu/fuel_rig.jpg) I pulled my ECU to see if it had any visible damage... It looks brand new (only brand new (looking) thing in the dam car.) I might venture to test the ECU in my other car. (IMG: http://www.adamanthony.net/mitsu/ecu.jpg) sigh

That ECU is a brand new replacement from the dealer. Nice find!!!
Now, please go do a compression test. It sounds like you are going in the wrong direction. If it had the accessory belts broken, the crank pulley could have seperated causing the PS belt to go around the crank sprocket and jump some teeth. The previous owner probably had the belt replaced in hopes it would just start running again. If the engine is spinning with no real resistance I bet you have bent valves.

I picked up a compression gage on my lunch break, and I’ll give it a try. I’ll do the compression check this week and report back.
When I had my plenum off, I took a look down inside with a flashlight and could see some of the valves. The ones I could see looked ok… well, they were caked with crap, but they didn’t look bent.
Shouldn’t my fuel pump turn on completely independently from all that? The fuel system is supposed to pressurize when the ignition key is set to on, right?
Aside from it being nice and shiny, how can you tell my ECU is brand new from dealer?
Thanks, AYD

Thanks Hans – you put me on the right track… I did my compression check, and here’s what I got… (IMG: http://www.adamanthony.net/mitsu/pressure_small.jpg) ZOOMThat’s right – zero! :( I took a look at my intake valves, and they look ok, but they were all open and didn’t move when I cranked it over. (IMG: http://www.adamanthony.net/mitsu/valves_small.jpg) ZOOMSo I pulled my valve covers and found what can only be described as…. a mess. (IMG: http://www.adamanthony.net/mitsu/rockers_front1_small.jpg) ZOOMNotice there are no rocker arms on the intake side? :( Notice the “extra” parts floating around in there? (IMG: http://www.adamanthony.net/mitsu/rockers_extra_parts_small.jpg) ZOOMThe same story under the rear valve cover… (IMG: http://www.adamanthony.net/mitsu/rockers_rear_small.jpg) ZOOMIf this isn’t a good demonstration of why it is important to keep your timing belt maintained, I don’t know what is… So this could be a lot worse… I think my valves are ok. The exhaust side seems to move as it should. The damaged rockers aren’t ground to bits… If I can find all the bits and pieces, and get t | |
