Everything was going just great (other than an occasional weird high idle/idling surge) when my Jeep died in the McDonald's drive thru...it idled REALLY rough/weak for maybe 30 seconds before it died, which led me to think fuel pump? So I called roadside assistance, and got towed home...
Now it cranks like a champ, but doesn't fire...I can hear the fuel pump when I turn the key, and it stops after a couple seconds...nothing out of the ordinary...bought a pressure tester, only to find out my 03 doesn't have the schrader valve...so I guess I will have to make a test hose, to go somewhere before the fuel rail to test the pressure...
From what I'm reading, crank position sensor is a possibility too? How can I test this?
Now, for the weirdness:
In the picture I'm attaching, what is the item in red (sorry if it's a stupid question...appears to be a vacuum manifold of some sort)? it has an electrical connector which hasn't been connected, possibly since I got the Jeep, but definitely for 2 years...I looked around and believe I've found the plug for it, but obviously this wasn't what was causing the problem, since it's been disconnected for ages
Also, there was a vacuum line that looks like it should have been connected to the intake manifold in the location indicated in yellow...it's the one furthest toward the front of the car, connected to a steel line, that appears to run towards the back, with the fuel lines...again, this looks like it's been disconnected for a while...
