Hi guys!

Please Help ASAP, our work truck has been down for 3 days now, a DIY engine replacement.

i completed the install of a 318 5.2 liter long block tonight and it really lacks power and is backfiring spraticaly when excelerating.

i was wondering your thoughts, and how to set the timing, or what to check. I did set the TDC and the rotor to number 1, first turn of the key and it was ideling, just lacks power when driving. Please HELP!

i am at my whits end trying to figure out how to set the timing, plus when Timing light is used it reads 5 degrees above TDC on the crank markings. Is there a advance plug to pull before setting the timing. BIG sigh

Sincerely Tommie

Installation To install, reverse removal procedure. Tighten bolts/nuts to specification. See TORQUE SPECIFICATIONS . On A/T models, ensure reference marks on torque converter and flexplate are aligned. Evacuate and charge A/C system.

When you install a distributor, you need to perform a fuel system synchronization, here's how:
FUEL SYSTEM SYNCHRONIZATION Tips Click a link to view tip Tip: Worn Intermediate Shaft NOTE: Fuel system synchronization is controlled by position of the distributor. Rotating of distributor WILL NOT change ignition timing, but will change fuel system synchronization. Fuel system synchronization should be checked any time distributor is removed or rotated. Connect scan tool to Data Link Connector (DLC). DLC is located below driver's side of instrument panel, to the left of steering column. See Fig. 1 . 1. Fig. 1: Data Link Connector Location Using scan tool manufacturer's instructions, access SET SYNC display on scan tool. Following scan tool displays, start engine. With engine running, if scan tool displays IN RANGE along with 0 , this indicates correct distributor location. The degree reading displayed on scan tool indicates the fuel synchronization, not ignition timing. 2. If scan tool display is correct, shut engine off. Remove scan tool. If scan tool does not display IN RANGE along with 0 , go to next step. 3. If scan tool displays a plus (+) or minus (-) sign next to the degree number, and/or the degree number displayed is not zero, loosen but DO NOT remove distributor hold-down bolt. 4. Rotate distributor until scan tool displays IN RANGE. Continue to rotate distributor until a reading as close as possible to 0 is obtained. Tighten distributor hold-down bolt to 16 ft. lbs. (22 N.m). 5. Page 1 of 1 ADJUSTMENTS - 5.2L (R1500) -1997 Dodge Pickup R1500 5/24/2009 If you dont have this tool, take it to a good repair shop and have them do it!

Great thanks for the details. What kind of scan tool is needed, and can I get it at a local store?

Thanks,
Tommie

Most that are capable of this are either the Factory DRBIII or an expensive snap on or mac tool type scanner. Good parts stores carry scanners that can do it, but they cost several thousand dollars, it will be way cheaper for a garage to do it, only an hour or so labor! Ebay may have DRBIII tools on sale by now with all the Chrysler dealers going out.

Okay, after several look overs I found that plugs 3 & 5 were backwards.I put them in the correct order and it runs great! Now my issues is that the A/C switches from vent to defrost (at the winsheld) when accelerating. How furstrating is this now :(
Any ideas from the pros?
Thank you so much for your support
