0411 swap woes

I finally got the car to be able to start and it will light off for half a second and immediately die. I double checked all the connections and wires and found nothing. My gauges appear to be working as well as everything else. I've got a 3 bar map and the 3 bar tune applied. The RPM registers on the scanner but not the gauge cluster.

I removed the fuel filters and cleaned them, there was a very small amount of trash in them. So I didn't think that would help when I saw them and I was right.

With KOEO the map reads 72.1kpa. I have 3 codes that I have no idea what the last two are.
P0452: Fuel Tank Pressure Sensor Circuit Low Voltage
P0748: Pressure Control Solenoid Circuit Electrical
P1637: Generator L-Terminal Circuit

Map sensor is 12223861 with the following wiring:

sensor ------------------------------------- PCM
A -- Low Reference ------------------------- B54
B -- MAP sensor signal ---------------------- R32
C -- 5 volt Reference ----------------------- B48

So I changed the map scaling to 305 and 6 offset and it runs. I need to find out the correct values for those 4 items.

disable vats?

just done this myself....only code i have is generator l terminal.....still charges so im not to worried....sounds like you have some pin missing or in wrong spot

and your pins are wrong on the map....mine pin out shows yellow wire from map goes to red 31 not red 32

You need to turn the code off for Gen L Terminal as that is the alternator output in which the 98 is not controlled via the PCM. So that output is not used on a 98 pin swap car. Also need to switch that function off in the options matrix by setting it to "0" on the table in the systems tab.

yes sir that is exactly i i had to do.....but i think he has some crossed circuits....
