im not getting any fire at all, i have replaced my PIP sensor, my module and the coil, have been checking power in all my connections and i am not gettin power to my TPS or MAP Sensor, which makes me believe i might have a sort somewhere in the wiring, could anyone tell me what to look for or give a detailed diagram of the wiring?

its a 1989 F-150, with a 302

 

Fuses & fuseable links? Can you feel the PCM relay pulling in when the key is turned on?

 

yes the PCM relay is pulling when the key is turned on

 

Check your Coil thread re: coil wires. Turns over, but no spark?

 

yeah it turns over but no spark

 

may sound dumb but does ur block have all the ground straps in place and do they have a good connection?

 

yes i have checked this

 

My diagrams don't designate between positive and negative. TPS and MAP share the orange/white wire, and also hooked to the EVP. I'm guessing that one is ground. Those 3 also share the black/white wire which I'm guessing is power. That black/white wire is also shared with the knock sensor, power steering pressure switch, ACT, ECT, and runs to the diagnostic connector. I've had factory splices come apart before so that may be what happened. Finding which one is power is easy if you hook the meter to ground and probe the wires, go to one of the other sensors on the list to find the correct power wire. Then you can temporarily hook the dead sensors to the working sensor wire to power them and see if it will run. Only connect them together if they are listed together in the groups above, none of those sensors can use direct battery power. The computer gives and receives all signals to the wires of most all the sensors.
