    I had the a/c compressor replaced. The mechanic fitted the compressor then started the car and regassed it. After finishing the regass he finished the job by pushing the wires from the harness into the correct spots and he tightened all the bolts. We now cant get the car to start. There is fuel, The car turns over, The diag codes show 55 (no problems) just no spark happening. I have now replaced crank angle sensor, and ignitor. but stil no joy

    Clean all connectors

    Especially ones already disturbed, ie. CAS & PTU.

    Chances are it was dirty CAS connections compounded by flooded plugs.

    Still not good

    Turns out the CAS had been poorly rewired and the wiring had disconnected down the harness. Now its running but very poorly. Had the timing done but still not good. It wont rev to redline, Usually will rev to 6000rpm but slowly and roughy. It stalls alot. I was told the knock sensor is not sending a signal and the temp sensor was reading incorrectly.......... Any idea's? Thanks

    Knock sensor error code is 34, ------>

    Coolant Temp sensor error code is 13. Which do you have showing?

    Both need perfect electrical connections... or ECU will be in 'limp' mode with sluggish performance like you indicated.
