No start 2.7L

[theroadisalover]

Im wondering if some of you Dodge people could help me on a couple of troubleshooting steps? Ok, Ive started with the basics.....Inj. fuel pump, intake vacuum, etc. I have 12 volts at # 1 inj. w/ key on. 12 volts at the 20 amp TCM fuse, 12 volts at the 20 amp SSR fuse. Originally , I did not see voltage at the 20 amp Inj/coil fuse. I read in a forum where someone jumpered his battery voltage from the 20 amp TCM fuse to the 20 amp inj/coil fuse locations. I understand the Auto shutdown relay can influence this no voltage scenario at inj. or fuel locations. Which, by the way, Im a little confused with the "Ign/Run" & "Ign/Run/st fuse locations. Can someone advise on this? Also, I noticed the fans running at all times when disconnected from Temp sensor, A normally open switch I suppose? Anyway, here's the basic steps I took.
Removed oil pan and excavated stripped drain plug clean out oil pan of blackened oil and golden pearls. (brass, of course) went back with pan. added 3 qts. 30w, 1 qt. tranny and 1 qt. engine flush. Cranked up and idled about 30 or so min. then died. When running, the engine had a faint knocking noise made much more distinctive by adding a little throttle. Second attempt. Now with oil change...3 1/2 qt. Quaker State 5w-30 with slick-50. Added 1 qt. STP oil stabilizer (prefer lucas) Tried forever to get it to start. no go. Waited for engine to cool completely. Restarted the next day. This time unplugged the fans from coolant sensor. engine ran 2 hours without dieing. Finally shut motor off. would not restart. Still wont restart!

Any advise at this point would be terribly welcome

A nostart condtion can be in one of four categories.

1) Starter motor does not turn or does not turn sufficiently to start the engine

2) Quality fuel not getting to the cylinders

3) Spark plugs do not spark

4) Insufficient compressin.

Start by narrowing down which area is the problem. Then narrow it down some more.

Try unplugging the cam sensor first before replacing it.The 2.7 has problems with the cam sensor.Sounds like you are looking into an engine replacement,that brass is from the bearings.You can put a 2.7 in it,$2,000.00 to $2,500.00 from an auto salvage yard if you can find one with no warrenty.You have this option and this is the best option,a 2.7 to 3.2/3.5 conversion.Yes,the 1998 and up Intrepids and Concordes with a 2.7 can be converted to a 3.2/3.5.A donor car is the best way instead of the kit,It is cheaper than the kit and you have the parts on hand needed.The 2.7 computer will work with the 3.2/3.5.I have done 2 or 3 of these conversions and it is real easy.
