hey guys I've had my truck swapped with an L33 with 4l80, factory ecu and de pinned harness... it's been running for a long time... but has sat in garage for a while behind other projects... I had it started about two weeks ago.... and then the other night went to start and cranked but wouldn't fire.... I'm getting lots of spark, the battery is good and full lots of power cranking... fuel to the rails... but I really feel like it's not getting passed injectors... I've never seen a code on this truck but all of a sudden got. a bunch for tps related stuff... nothing has changed and I'm not awesome at trouble shooting with the multi meter.... any advice?
I tested my tps harness and all seems good... when I back probe the two signal. wires I don't get my 5volts on either with wot... I get 3.44 on one and 3.88 fly open... it says online min 3.5,...is it safe to assume my tps is shot?
