my 01 has been giving me headaches the last couple years during the summer. It usually starts and runs fine mostly during the cooler months if I just drive it to work and home and maybe stop at one or two places.....but when it’s really hot like today (about 98 degrees here in SC) I just drove it home from work about 15 miles, parked it went inside for a few mins then came back out to spray down the front end bolts (since I’m doing ball joints this weekend) and I tried to start it to turn the wheels to access the bolts and it started and then stumbled and shut off. This is just like it has done a few other times but this time I was home and not sitting in a parking lot somewhere. So I was like great I can try some things on it that I have seen on the forums to see if it’s something simple. I messed around with the fuel cutoff switch on the passenger floor board....nothing. I tapped on the IAC (of course I cleaned it about a month ago) nothing. So I said ok let me spray some starter fluid in it.....bam it runs....albeit smooth for only a few seconds then it’s rough as hell....makes sense to me it’s not getting fuel. SO! My question to you guys is....wtf is my problem???? Fuel pump? Fuel pressure regulator? Has a new filter so that isn’t it....sure seems like vapor lock to me since it’s only happening when it’s super hot...but I’m told that’s “impossible” on fuel injection. Really need some ideas before I start throwing money at it.....any Help greatly appreciated!
