engine is a 2g with evo3 intake, ecu and turbo... evo8 pistons, 750cc injectors, ecm and sd... it just suddenly happened after fixing the starter... car starts but when you press the gas pedal, it just chokes and dies... check the ecm, it says tps... traced everything and everything checks out fine... has continuity and all... but during log tps stays 0% and maxed out at 33 resitance... any thoughts? and i used the car the day before

I believe you should be able to watch the TPS range on your logger. If it never moves, the engine has no idea on throttle opening.

Yes my TPS is from 10% to 99.6%

I had a bad connection on my TPS and had similar problems

Found out its not the tps. I made a straight line to the socket to the ecu and the omni 4bar map. When i connect the map to the 5v source it only registers 1.3v but disconnected, with only water temp and tps connected it reads 5v... Tried a different ecu with my ecm still doesnt work. My ecu with a differnt ecm still didnt work. Swapped out a new map sensor, still the same. Dont know what else to do. My harness is now a mess... And thinking of just getting new harness
