I have a Chrysler 2005 Pt Cruiser 2.4 L (non turbo) automatic engine! I recently had a new fuel pump installed, drove it about a week, it shut off at red light and hasn’t started since!
And it is not throwing any codes. I have replaced the fuel pump, spark plugs, ignition coil, spark plug wires, cam shaft sensor, crankshaft sensor, oil sending unit, battery, fuel injectors, and the ECU! I have spark, I have compression, and gas is getting to the injectors, but it still won’t start, it is cranking over strong, but still won’t start! I sprayed starting fluid in it and it started up and then shut off, I started it 2 more without using anymore starting fluid and it started up but shut back off! Didn’t t want to use anymore spray unnecessarily! I am at a lose, I am baffled by this, do you have any in put as to what I might can try? Thanks for any input!
I'd check if that new fuel pump was getting pressure AND flow to the injectors, then if the injectors were getting the correct electronic signal. You should probably be able to Google up some Youtubes on doing these procedures with consumer-grade tools(Scotty's are the best).
As you know this car doesn’t have a schrader value (pressure point) and the fuel pressure regulator is in the gas tank. Where would be the best place to attach the hose for the pressure test? I removed the bolts and lifted the intake a little and then pulled off the fuel line from the firewall to the fuel rail. Blew air through the hose and it doesn’t seem to be stopped up! While hose was off I turned the key to the on position I heard the fuel pump engage but no gas what so ever came out of the hole at the firewall line.Shouldn’t gas have come out when I turned the key on? So where should I connect the hose for testing? Thanks for
Your help.
Sine the pump is turning on, that;s good, but If nothing is coming out from the fuel line outlet at the firewall, then odds are you have a failed fuel pump - if it was a clogged line or fuel filter, you'd get a weak flow, but turning on with no flow means its time to shop for a new fuel pump.
Get is scanned for codes to begin the diagnosis. Throwing parts at it won't get it.
Are you sure it was the fuel pump priming? I know there are some issues with fuel system in some of the pts. I haven't personally seen but have heard from multiple other mechanics about relay issues with these cars. I have also been told in past some have a wiring harness issue that can cause a crank no start condition. I'm not sure what years are affected but that something to look into.
Fuel pump relay, wiring harness.
Got it scanned and it is throwing No Codes at all!
