Ive recently been getting some weak starts when the car is warm and has been sitting for 20 mins to 1 hour. Anyone else get this on e85? Earlier today it failed to start, it cranked for a sec, kind of started, but died, worked fine after starting it again. Stock fuel system, pbd tune, I had not had this issue but I did get a MAF sensor plug fixed recently. Wondering what could cause this.

My guess is the fuel pump. Sounds like vapor lock.

Check cranking and running fuel pressure.

All I got.

Did the issue show up at the same time as the MAF plug replacement? Strong likely hood its related. If the new sensor is installed properly and is verified not faulty, then yeah check your fuel pressure.

I also had weak warm starts with my PBD tune initially. I never addressed the issue with them but did receive a few revised tunes and doesn't seem to be an issue anymore. Have you contacted PBD on the issue? They have always gone above and beyond anything I have ever needed

Did you say Andy you wired in your electric cut outs through or close to your MAF wiring?

Been on E85 over 2 years and zero warm or cold start issues.

I have had this on two cars with a Roush blower. Only warm.. Never cold. Starts up like a champ in the morning. Every once in awhile though it starts like it's tired.
