Starting up issue

infinitekidM2C · 07-18-2017, 12:18 PM

My car tends to really take a few cycles to start, usually does not start up quickly. Once it starts its fine, but it regularly takes a while to start. Anyone had this experience. For background info i have changed my plugs, coil packs, battery, and the car is fine all the way to redline once it starts... Maybe i should walnut blast her?

So it turns over and has spark?

Is your LPFP priming?

infinitekidM2C · 07-18-2017, 07:38 PM

Yes to both; i hear it priming before i try to start. Injector leak?

I'll vote for the HPFP.

Long cranks are usually indicative of an HPFP issue...

i mean i did get the recall done with the HPFP a long time ago...i actually had the car checked about 3 months ago and they didnt see anything wrong and i noted possible HPFP...maybe ill get another opinion..

i had long cranks followed by a p29dc code (cylinder injection shutdown) bear redline anywhere from 5-7k rpm, replaced hpfp, and no more long cranks and care felt much better but i still had p29dc and its def the LPFP. Although if long cranks are all you are suffering from HPFP will definitely solve your problem.

Thanks for the responses guys. Mine's a 2008 March so i'm going to just be inside the extended 10 year warranty if it turns out it is the HPFP!
