wiring and plumbing for engine finished and first crank attempt was a fail.

looks like its not happy with crank signal agreeing with cam signal.  hopefully its just two pins swapped on the ebay harness and it will make spark then ha.


dash gages look sweet and fit right in!  super happy that the ones i use on chevy trucks (that are a pain to fit) just bolted in with no mod.  Ill probably get another set for my other international truck. GPS speedo is nice.

more time wasted on this thing and no fire.

my scan tool i cant seem to find CMP signal for this model year.  tried swaping pins and i do get a few pops now.

verified fuel pressure, injectors are free and flowing fuel.  checked PCM is spraying fuel on #1 and #2

see cranking RPM (crank signal?) but have Cam signal code. 

i assume its trying to spark because i have some pops and bangs. 

bah

pushed this thing back into the work bay for the first time in months. 

pined out some things and did some diagnostic work.



found MAP and CMP senor plugs (same plug) swapped on engine after pinning out sensors to PCM

fresh 5.3 base tune and got it fired finally!  starts, stops, moves, steers. 


i was about to give up on this ebay harness.  be good to get back working on it this fall!
