Welcome to Code Hell!

So I thought it a good Idea to Turbo my 92 acclaim the engines from what I can remember as a 1990 Dodge spirit turbo. It started sputtering and dieing goin down the freeway when I pulled over and shut it off I couldn't get it started, I towed it home checked codes its comin up 12, 61, 37, 41 I've read what most of these mean but that doesn't mean I know what or where they are. Can anyone tell me A which of these codes would keep the vehicle from running, and also Where or what some are.

37 Shift indicator light failure, 5-speed
OR
part throttle lock/unlock solenoid driver circuit (87-89)
OR
solenoid coil circuit (85-89 Turbo I-IV)
OR
Trans temperature sensor voltage low (1995 and on; see NOTE 2)


None of these seem to have anything to do with me?! Its an Automatic and doesnt fit between any of these years? Maybe I'm off on the year of my engine If so Solenoid coil Circuit, or Part throttle lock/unlock solenoid driver circuit. What are these and where?

41* Alternator field control circuit open or shorted

Not even sure what this is

and I know 61 Is "baro" sensor opened or shorted

I have tried 2 diff map sensors and another Baro but virtually nothing changes
I've checked for spark and for fuel both seem to be there.

Any help would be Great! Thanks

how old is the battery. how old is the HEP.

battery sprang to mind first. my car blew like 10 codes the other day and it was a lumpy battery ya alt may be shot that would pork ya battery. have it tested at autozone or whatever,

if its an ND alt have it rebuilt they are getting rare. check all the fuses in the PDC also

Sorry I'm Kinda new to these cars. Whats an HEP. I'll try a diff battery.

I helped build this car, and I was the one who originally located the donor car for this project. Just to confirm, I am 100% sure that the donor vehicle was indeed a 1990 Spirit.

Come on Chris, the HEP is the Hall Effect Pickup inside the distributor... you should know that!

What probably should have been mentioned in the initial post is that the car is getting both fuel AND spark. Wouldn't a bad HEP prevent spark output?

[NAJ]

Not necassarily, if it was the fuel sync side of the HEP you would still have spark but a no-start plus a code 54.
You changed components but never checked the circuits for the components.
Clear the codes, be sure they are clear, crank the engine for 10 seconds and recheck the codes.
What codes returned?

[loud1420]

So I reset the codes and came up with a code 37 then I pulled a relay code 34 and 37 then I pulled a diff. relay code 37 and code 42. Then I pulled the last of the three on the firewall this time only the code 37 ... Anyone know what those relays are?

[NAJ]

The relays on the left fender are (front - rear) ASD, A/C Clutch, Rad Cooling Fan.
The Baro Solenoid is on the firewall next to the Map Sensor. It is an on/off solenoid with 3 ports, manifold vacuum in, manifold vacuum out to Map, a vent (remains open, no line or plug).
