2001 Jeep Grand Cherokee does not start the first couple of times

Dear Doctor: I have a 2001 Jeep Grand Cherokee with the V-6 engine. I have to turn the key over three or four times to get it started. It does not start the first couple of times. The fuel pump was changed and so were a few other parts. Any suggestions? Gary

Dear Gary: Use a scan tool to monitor all sensor information including coolant temperature voltage and idle air control. We have replaced many idle air control motors on these vehicles. Another common fault is the crankshaft position sensor. I always check the basics before attempting to jump in and replace parts. Information is vital before any repairs are made. I even recommend a recheck of the fuel pressure. I always look on the Identifix web site for other vehicles with the same condition. Alldata lists the correct specs for all engine sensors and how to properly check them.
