So my car has some problems starting up...

Usually it will crank and start up right away in the morning when cold. Then when I let it sit for anywhere between 1-5h and I start it up again...it will crank for 2 seconds...fire up...kinda feels like its clogged or something...and then either immediately die...or start up kinda rough and then normalize. If it stalls, and I try again it will start up immediately..and run like a champ...

in order of probability i am looking at...

1. coolant temp sensor

2. fuel pump..

3. crankshaft position sensor..
