Openly looking for suggestions my brothers. Wrapping up a build and I'm having trouble getting it to fire up. Managed to get a couple backfire the other day after finding a broken ground but still nothing. Originally the 032hs ecu was not communicating because of damaged pins so I flashed an original awp file to another one while going about the immobilizer the quick way and swapping the chip. Do I need to actually defeat it? And just about everything on the car is new sensor ,ignition, fuel system wise.... appreciate any help

Marty you were spot on with it completely consuming all of your free time lol. Honestly at this point I'm willing to pay for a base map just to get it started. Only new addition to car is I went to a gt35r but still same 620s on a 4bar.

fuel lines correct i think.... (one going to large side of fuel rail is the one closest to the firewall, blue return?) mas has the element exposed on the bottom of sensor.... yes i verified timing.......... first crank attempt i did hear something that i didnt like but instantlly went away. maybe dry cam tensioner at first.. did pull valve cover and didnt seem like any valve interferance took place. but i know that breaking valves on these motors is damn near silent and instant.

can i flash onto a 032cl tiptronic ecu? or am i going to get yelled at for asking? lol  Grin sorry to bug ya buddy appriciate you

do you have spark compression fuel and fire gotta start with those first then check compression with a guage and then timing also and that will help if ecu is good!

All checking out good. Nothing was rushed at all. Iridium  ngk. new coils new harness new f pump new for new fuel filter Still know just about enough to get me in trouble tuning. Going to check compression tonight.

Never cross flash unless you know what you're doing.  If you have checksum errors you're flashing bad files.
