slow to start

AZ_SS · June 17, 2020

lately my truck has been slow to start, primarily first thing in the am, at other times its fine. The starter seems to turn over at regular speed but actually turns over what seems like 5 seconds or more before starting. I had O'Reilly check the battery and they said it was good. Any ideas? Thanks.

I only have that happen when I run E85 or it's really cold outside. I doubt that's your issue at this time of year.

A really nice scan tool would let you see the low and high side fuel pressure, it could be taking longer than normal to build pressure.

Unfortunately I don't have a scan tool. I was thinking maybe fuel pressure to, ill see if it does it after sitting at work for 10 hrs today. Not sure why i would start loosing fuel pressure all of a sudden. Truck only has 22k on it.

A valve can fail so that fuel drains back into the tank over time, and that 5 seconds of cranking is the fuel pump re-priming the system

The truck sat in the parking lot for 11 hrs at work yesterday and didn't do it. This morning i turned the key on for 5 seconds or so before trying to start it, to allow the the pump to build pressure and it did not do it. Maybe it is loosing pressure. I will jump in and start it tomorrow morning and see what it is does.

So I have been putting off further investigation hoping to get by until it cools down but I noticed a gas smell yesterday when I got out of the truck. I couldn't see any signs of a leak under the hood or any obvious leaks under the truck, so I took it into the dealership. Turns out there is a nipple on the pump leaking and they have seen it on a few city/police trucks as well. So apparently this is not an isolated incident.

Glad to hear they were able to find the problem.

Think you have your band name if you choose to start one....
