SilvySS Posted June 16, 2014 Report Share Posted June 16, 2014 Ok here's my issue, I can cold start my tuck in the morning starts just fine, I can leave the truck sitting for about 25 min after it's warm starts fine however if I let it sit for anymore then 25 min it cranks several times before starting. So to recap, cold starts fine sitting for under 25 min starts fine but if the motor is a little warm takes several cranks to start (this is hard to explain typing it out) I'm just so lost I have no other issues no rough idling no bogging no lack of power, I already replaced the fuel pressure regulator and still dose it fuel pump maybe?

Downeast Johnny Posted June 16, 2014 Report Share Posted June 16, 2014 Was your fuel pressure reg. bad? It could cost you a fortune to guess at causes and throw parts at it. The only in tank style fuel pump that I have had go bad went from hard starting symptoms to quit altogether within 20 minutes and about 10 miles. (93 Silverado). My 03 SSS will crank for a second or so before starting every once in a great while. (Nothing consistent, or regular) You might try pulling a plug and checking it out. Do you know how old your plugs are? Good luck chasing down the trouble. Quote Link to comment Share on other sites More sharing options...
Cb-air Posted June 16, 2014 Report Share Posted June 16, 2014 Following your "issue". I have the same problem here in Dubai. In the morning when temp is 30C (85F) it's cranks just 1/4 turn & it's starts, but in the afternoon, when temp is +45C (120F) i have to crank it 3-4 turns before starting. I have not done any trouble shooting yet, but suspect the pressure regulator... Sent from my iPad mini using Tapatalk HD Quote Link to comment Share on other sites More sharing options...

Fireman31 Posted June 19, 2014 Report Share Posted June 19, 2014 *Topic moved to correct section* To the OP, if you have tried the FPR, next step is most likely the fuel pump. What year is your SS? How many miles? If it's an '03, try replacing the fuel filter first before going to the pump.... Quote Link to comment Share on other sites More sharing options...
