So I just converted from aod to t5. Curse would start out no problem even when I took the old transmission out. Got everything back in bypass the neutral safety switch. I know the battery is almost dead so I will rectify that and a couple of days. but I can't get it to start but only runs for him anywhere between 2 to 5 seconds and then it immediately shuts off. The transmission speedometer sensor is not hooked up but as I said before it started up no problem before all this. It is a neutral and the car is not engaged (stuck in gear) in any gear. Fuel pump is definitely priming. just did a full tune-up on it prior to transmission swap. if anybody has any information or has dealt with this before would be very much appreciated I'm ready to have my car back on the road. Thanks in advance
