help oh by the way i am using stock wiring harness and stock ecu thanks

 

ECU from a B20 ?

 

ya i guess that might work too anyone have one?

 

Are you throwing a CEL?

 

ya i am i took it to autozone to put ir on the code reader and came back misfire clynd 2,3,4 so as of today i but a obd2 jumber to obd1 and plugged in a 95 ls p75 ecu and now its still not working right has anyone done this swap if so really need some help thanks

 

... Have you checked your firing order?

 

ya everything is fine and as my lights are dimming out and coming back bright and my battery is going dead too so im not sure what it could be thanks

 

ok i put the obd2 to obd1 jump harness and how its not letting me rev past 3,000 anyone know what it might be thanks

 

You either have a) a short somewhere b) a connector not connected or switched with another sensor c) ECU is f'ed d) bad distributor...and a hundred more things, but those came to mind first

...it really is almost impossible to diagnose electrical problems on the internet...buy a Helms and a MultiMeter and start figuring it out.

 

well figured out why the battery is not charging was loose wire to the alternator but other then that i changed out the injectors and still nothing im using a p28 and nothing also rechecked the wiring harness and everything is in the right place...

 

Check all grounds. 1 on tranny. 1 on front side of engine. 1 on battery.
