My landlord asked me to help his guy that does work for him on the buildings on his rental properties. Has a 2002 Dodge Ram 1500 that threw a rod. Is a 4.7 V8. First used engine replacement attempt was a 4.7 out of a Dakota year 2003 and did start but a lot of the brackets and other install components did not fit and when it did run, the idle would always fluctuate and then the engine would die and then would not restart till next day. So, as it turns out that when I drove to help him, 15 miles away. that he has a small salvage yard. He had a 2004 Ram 1500 with a 4.7 engine that was in a wrecked rolled over truck. He ripped out the Dakota 4.7 and installed this engine. Then he put it all together enough, minus radiator and all components at front of engine. Now it cranks over and spits while cranking and using starting fluid it fires off for a second and flames out of the TB. It has spark but sounds out of time. He has tried numerous cam/crank sensors and even an IAC valve. My scanner would not hook up/mate up and said that no info to send. I looked under the hood of the 2004 and the ECM had 4 harness connectors and the 2002 ECM had 3 connectors. Saw a few harness connectors that were hanging. Further research found that the 2004 is a Flex Fuel truck, the 2002 is a gas. FF did not start for Dodge, till 2004. Has different part numbers for some components and I also found that the Crank sensor tone wheel is different. I told him he needs a different engine or to swap all computerization and harnesses. See pics.
