How do i reconnect the dastek unichip I have removed it due to not starting and suspect the chip,only to find out it was the crank sensor.

sounds like crank sensor or cam shaft sensor. Internal resistance due to heat, hence why you can start and run car in morning, ie cold. When the heat build errors start. Get codes read first but I would suspect these 2 sensors. Yo can also get fault new parts, so you might be one the right track.

If your looking for a magical fix forget there aren't any ! Electrical testing is the only way to find problems . When it won't start , what's missing ? Spark , fuel pressure ? What's with the jet chip , what do you think that's going to do . Replacing parts without testing an knowing for sure , is not the way to a proper fix . Did you check the crankshaft position sensor ,

Just because there is fuel does not mean it is at the right pressure. Test the pressure or use a can of Quick Start Fluid, using extreme caution. If it does not start with Quick Start, suspect the ignition switch or Crank Angle Sensor. Crank engine to see if tach moves. If not, replace.

why not ask UNICHIP.
it is their piggyback. ask them. it a custom hack for a car.
how it fits your unstated car and engine, is not knowable.

be careful , if compatible , and emission controls

Hello
HAve you checked your air flow sensor
Thanks

Code 11 - no crank signal at pcm
Code 27 -#1 injector driver does not respond properly to (pcm) control signal
Code 32 -EGR solenoid circuit
I would replace your crankshaft postion sensor, the sensor is located at the back of the right cylinder head (closest to the firewall) in the transmission bell housing... disconnect the wiring harness to the sensor -- use a 10mm socket or wrench and remove bolt - pull sensor straight up and out.. when reinstalling new sensor push in to bell housing - tighten up bolt and reattach wiring harness -- (before you do this operation make sure that you have disconnected the negative terminal on the vehciles battery.

Make sure that check engine light comes on when you turn the key to the on postion,then while cranking it should go out,then while cranking after a few seconds it should come back on. If it does not then PCM is not seeing a signal from the crankshaft postion sensor.
This sensor is located on the front passenger side of motor at the crankshaft pulley.You can disconnecting harness and clean it and reconnect it and see if it cranks. If not replace it.

ok check your timming belt then your ckt sensor the chip will not let the truck even crank or let the dash come on
