Argh- I rebuilt a 2.7l this winter. Everything went very well with no obvious problems. I installed my engine, hooked up all the hoses, filled with oil and hooked up the starter. I had problems with the starter wiring however I finally got them resolved. I was getting 12.6v at the starter. I cranked the starter and the engine turned a couple of times then stopped. When I would crank the starter again, it would just sound like a starter with too low of voltage- the solenoid would shoot out but the starter wouldn't turn. I checked voltage and it was 12.5v. If I look at the fan blade when I crank the starter, I do not see it move even slightly.
What are my options of what could be wrong? I see it as a starter problem or the engine is somehow seized. I do not have the axels hooked up so I cannot see if the engine turns by pushing the car in gear. I have a small window cut in the firewall so I wiggled a 19mm box wrench onto the timing pulley nut. I tried to see if I could turn the engine even slightly and I could not. I couldn't put much force into it however I would have thought it would have moved to some extent. I think I will remove the starter and see if it cranks off of the car. If it functions properly, how can I check to see if the engine is seized without installing the axles. Is there anything common that could cause this issue? I would really prefer not to remove the engine. I am getting somewhat sick of working on it. Any ideas? |

Is there a chance that some of your fasteners in your clutch/pressure plate/flywheel might be standing off and interfering somewhat ; not allowing free movement. Any metallic , or clicking noises while it turns over?
If it is just a weak battery, try putting a fully charged jump-box on the battery while cranking. This happened to me with a g50 installation, some of the bolt heads were a bit too tall (in the clutch assy.)and whipped against the pressure plate. There was some noise and it was not cranking at speed. I slipped the trans from the engine, removed the clutch assembly, fixed the problem with shorter profile bolts, and that solved it. If your 2.7 turned freely with a wrench on the stand, it should still turn freely with a starter. (IMG:style_emoticons/default/idea.gif) Marty |
