have a b20 swapped 98 si with a chipped ecu and obd2-obd1 conversion harness. car wont start atm. took to a garage they cut into the engine harness and added sensors that were missing from when i bought the car.
with an obd1 what are the only sensors i need? the car still isnt running

 

Shouldn't need anything...run as is with obd1 ecu. Bad shop....

 

more info needed to help. what happens when you try to start the car?

 

Post CEL codes. Get ready to replace the now-hacked-up harness that the shop fucked with. Never bring your car to a regular shop again.

 

98 Si?

That's what I was thinking, but I'd like the OP to state what he has just in case he thinks he has an Si and he actually has something different.
