there is a relay on the driver side firewall of a 89 trans am tpi with 5 wires going into it,RED BLACK/WHITE PINK/WHITE BLUE ORANGE. what is that relay for?


Relay get warm when its plugged in and car has a slow throttle response, like it drops about 100-200 rpms before accelerating, its got new MAF, ESC, IACV, ROTOR, SPARK PLUG WIRES, SPARK PLUGS, DIZZY CAP, DIZZY MODULE, COIL, TPS was adjusted and its within specs. WATER TEMP SENSOR,

When i unplug it it runs way better with a very fast throttle response but i get a ses MAF HIGH and ESC FAILURE.

Please help me identify this sensor.

Its a 350 with '165 ecm, chipped by tpichips, 24# injectors, fuel pressure ~45, LT1 intake conversion.

 

I know 1 is for the mass air flow burn off circut, and one is for the fuel pump relay and I think the other is a cooling fan relay.

 

yeah but w/o fuel pump my car wouldnt run so it cant be fuel pump relay, my fans come on when hot, andi replaced my maf w/ a brand spankin new one and still the same problem. but if i unhook the relay, tahdah
