Hello, I have an 89 ford bronco II with a 2.9

The turn signals and brake lights use the same circuit and filament in the bulbs. The tail lights are on the other circuit which comes from the headlight switch.
Do you have power on the tail light fuse ?

Iac sensor it controls the idle so swap it off your old motor!

Yes.
Regards, David

replace the fuel filter

Try replacing the Throttle Positioning Sensor
Have the codes checked
You may need to clean the Mass Air Flow Sensor
this is best done by a professional as it contains some very sensitive wires and they are easily broken
The MAF is very expensive to replace

The solenoid on your starter is probably no good. Just get a new starter. Theres no starter that will "grab the teeth better", theres just new ones that work and old ones that **** out

all the early rangers up to the genII and maybe even more will work in you bronco....join the ranger station forums for a lot of insight on your bronco...

1-4-2-5-3-6
Now you need to know which cylinder is which. If you stand at the front of the truck looking at the engine, the number 1 cylinder is on the left closest to you. The left bank has cylinders 1-3-5 and the right bank has 2-4-6. So number 1 is at the left front and number 6 is at the right rear.

either the brake booster is bad or the check valve needs replaced thats the little elbo the hose connects to

No.
