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? |

I checked several things and didn't have any luck. I removed the starter to see if I could turn the engine without it installed- didn't work. I checked the wiring again and all was ok. Removed spark plugs and no change. Of coarse the transmission is ini neutral.
It is strange cause the engine will not turn at all- even slightly either direction. When I first turned on the starter, it cranked 1-2 revolutions. I did a partial rebuild. I did everything from the cylinders/pistons out. I did not have any binding issues at all during the rebuild. I could easily turn it by hand. One of the last things that I did that moved the crank was when I mounted the flywheel. I everything turned without difficulty. After than I mounted the clutch, pressure plate then the transmission. I didn't try to see if it turned ok once the transmission was installed. So unless there is something that I am not thinking of, there has to be something wrong around the flywheel. Another thing that I thought of was what if bolt or something fell into one of the intakes? First, I looked into the bores with a borescope and didn't see anything. Also, if something were stuck in a cylinder, the engine just shouldn't turn one direction. I should be able to back it up without difficulty. Has anyone else had an issue with something binding around the flywheel? I saw Marty's post which may possibly be my problem. |
