Stall on startup?

[Mhenderson]

Hey guys I've been running the ots1.59 maps since they came out and just recently started to get intermittent stalls immediately after start. When it stalls and I press the start button again there is a long turn over time before it starts probably 10 seconds but you know how those things seem like forever. Anyone experienced this before or any ideas what is going on? It's only at 3000 miles.

Thanks,
Michael

are you on E85 ??

if straight petrol sounds strange, unless you got some bad fuel, does it run ok after startup ??

Yeah straight 92. Happens very intermittently. After the long start it fires right up and runs like normal. If I shut it off and fire it back up no issue.

You need to make sure your system is holding residual fuel pressure. Check valve in the pump could be going bad. This can happen intermittently. This will usually only show its face after the car has been sitting for a while and then started (Cold start). After it gets running and then shut off there will be fuel in the lines still so startup will happen normally. Long cranks are often a result of the fuel taking its time to get back up to the engine. Just one of many things it could be but it would be one of the first I would check.
