A COMMON PROBLEM I'VE SEEN MANY TIMES IS THE CRANK SENSOR DISRUPTING COMMUNICATION WITH PCM. UNPLUG THE CRANK SENSOR AND CHECK FOR RESPONSE OF PCM. IF COMMUNICATION IS NOW POSSIBLE YOU HAVE A BAD CRANK SENSOR. IT'S A PROBLEM I'VE SEEN NUMEROUS TIMES. DOUBLE CHECK YOUR TIMING.

If you have a bad booster you would have a really hard pedal and it would take two feet to stop. Sounds more like a fluid leak or a bad master cylinder. Are you adding fluid or do you have a red brake light on?

When the service engine soon light (Also called the check engine light or engine management light) is turned on this is to alert you to the fact that Powertrain Control Module (computer) has detected a failure somewhere in the systems it controls you may not feel any difference in the way the engine runs, this can be the transmission or the engine or emission system, there are fault codes set in the modules memory for these faults. What needs to happen now is to have the powertrain control module scanned with a special tool called an OBD2 electronic engine control scanner or a OBD2 code reader. Once the code(s) are read then you must perform the diagnostics for each code and make the appropriate repairs based on the findings of the diagnosis that was performed, this is called doing "Pinpoint" testing.
