Here's the best description I can make.
Recently my car has had problems starting up. It will start then the engine will 'romp' between 1500rpm and 300rpm almost dying and sometimes die.
Twice now the car has taken 10 starts to start up. But this has only happened when it's hot. Not when It's cold.
So, like suggested before and I posted pictures of it I checked the fuel pressure using a harbor friights fuel pump and it came out to low pressure of 25 WHILE DRIVING and 20 while not driving. The fuel rails hold pressure fine.
I'm about to put the pump where the fuel filter is and check the fuel pressure from there to isolate the pump from any other fuel regulators on the car and see what the pressure is there.
Recently I have changed the air filter, MAF sensor and made sure the fuel filter is clean (2 days ago). I'f I get good pressure from the fuel pump I'm going to swap the olf MAF sensor back on as it wasn't bad to see if that's causing an issue. I'm also replacing the IAC under warranty for kicks as that could be an issue.
But after all that I don't know what to do I'd like a bit of advice on what anyone thinks could be an issue and what to check.
Thanks
ps... every time I start the car today while working on It I'll have the video camera ready to try to catch a good example of this.
Once again thanks guys.
