Hard start since swap to turbo

[fleebag]

Ever since swapping to turbo it has trouble starting once warm.

It’s not a starter issue as it turns over great.
Played around with cranking ve but no luck.

Read an older post from other site possible iat heating up?maybe relocate?
Cold start is fine only once to operating temp does this happen.

I’ve tried two different tuners tunes with same result.

Just got stranded at grocery store lol went back up there 40min later and started fine.
Thanks in advance

I don't think I worked with you on this.

I am just thinking out loud here, it could be vapor lock, the fuel boils in the fuel rails because there in no pressure engine off if you have a return system.

You can add a check valve to hold some pressure and reduce the possibility of vapor lock.

Thanks man, no we never finished what we started lol.

I did play with the cranking fuel 150* up and has gotten better. Even last night I got back in the car and it showed 210* and first turn of key it only turned over. Second turn it fired up

As for fueling, I'm return oem style.
Thanks again Ted

It's hard to understand what you're saying here. Do you mean the engine doesnt turn over at all? Like dead battery? Or are you saying it turns over several times, but doesnt start?

I've had batteries that test good with a Volt meter, but when the engine gets hot, it wouldn't turn the motor over. Check it with a volt meter while cranking hot, and you may find a huge drop in voltage. If so, replace.

If you mean it is turning over easy, but not firing up, then try adding some airflow to this table.

Yes it turns over fine, no problem. I'll test with that airflow table next.
Thanks, appreciate it.
