When I got into my truck today and turned the key, the engine cranked almost 3 times as long as it normally does...and I had my spark plugs and fuel filter replaced about a month ago. What else could be causing this? Air filter? Fuel Pump? (i'm new to this stuff)
I have the 3.4L V6 btw
Thanks in advance

 

My cranking time was creeping up there...I changed the plugs/wires/fuel filter/ran a bottle of SI1 Red Line injector cleaner...If you haven't used a injector cleaner yet you may need to run a second bottle...Clean the MAF air filter and throttle body -these maintenance items brought my cranking time back to under 2 seconds
