03 Trilogy tuned at Lidio. Aeromotive Stealth fuel pump. Boost-a-pump (dialed down low), relatively new spark plugs, JLT CAI
A few days ago I put the battery back in the car and it fired right up. I made a few short stops and it fired up fine each time...until it didn't. After about a 20min drive it sat for about 30-45min and then it wouldn't start anymore. Turns over fine. After a tow home I checked all fuses, they look fine. I noticed I wasn't holding fuel pressure at the rail (I have a permanent gauge at the Schrader valve) so I swapped out the FPRS and now I have good pressure readings but still no start. I took out a plug and it showed good spark. It was drenched in fuel though. I took out all the plugs and sprayed with carb cleaner and left them out of the car over night in hopes any excess fuel would evaporate from the cylinders. Put it back together and still no start. I tried holding the pedal down while starting too. The anti-theft light does not blink when turning over and the check engine light isn't on either. I tried all 3 of my keys.
I am definitely getting fuel, maybe too much? Could I be flooding myself out every time or maybe never recovered from being flooded the first time (when FRPS failed)?
I haven't tried cam or crank sensors yet but shouldn't the injectors stay off if they were bad?
I looked for the infamous crimped wire bundle running around the cam cover but nothing seems too tight or bent in that area but it is difficult to be sure since it's hard to do anything back there.
Any ideas would be appreciated!
