Hello
Here is the vehicle info
2002 chrystler sebring 2.4L DOHC
Car was having trouble starting and needed to have the key turned to the on position for several cycles to get the fuel pump to get the correct pressure. But even so the car did actually start and run after it got started. Now I have switched the fuel pump and it will not start at all. I can hear the pump running but it must not be getting fuel to the fuel rail. I think i have all the EVAP hoses routed correctly(would that matter anyway for starting?). It is a huge pain to have to redo this project so I am looking for tips on what I should look for in foguring this problem out.
Thanks

Re-check your work… Also if you have a fuel pressure gauge you can try to test your fuel pressure at the rail…

I do not have a pressure gauge but I cranked it over for about 15 seconds and pulled a plug very quickly (30 seconds) and the tip was bone dry. The valve on the rail is not easy to access (way to go Chrysler). So is this a good indication of no fuel pressure. Also I did take the fuel line fitting off of the pump when looking for mistakes, and only a few drops of fuel came out of the line (this was after cranking it till the battery died.
Im starting to think that the fuel pump i got does not actually pump fuel even though it turns on. Today I added more gas to the tank just in case it needed more to get started (total in tank is about 5 gallons).
Should i try a new pump i got this one off of ebay for about 1/4 the cost of a new one. The pump from ebay is a little bit longer and has a different fitting for the strainer Here is a link to the pump that I got.

Since you were having issues with the old pump and a new pump is having issues… Before you write off the new pump….Try this… Trace the fuel line from the tank to the engine compartment… Look for any kinks or bends that should not be there….
It could be you have a kinked or blocked fuel line under the car which may be causing this issue…
Is there an in-line fuel filter?
We should call this a “fuel-delivery” issue before we call it a bad fuel pump…
Just my 2 cents…
-Karl
There is not an in-line filter. The only kink I ever noticed was right where the quick line connector hooks up to the pump I will have to drop the tank again anyway so I will check the lines where I could have kinked the getting the tank up or down.
So what about the EVAP system on the tank is there anything that would cause the pump to not be able to pump fuel to the rail?
The EVAP system should not cause the fuel pump not to work…. The EVAP system just holds fuel vapor and sends it to the throttle body when conditions are set… It works on a vacuum system and in proper working condition, is contained unto itself…. Hence why a vehicle can continue to work with multiple EVAP system codes and have monitors that are not ready….
If you hear your fuel pump running, it is running…
-Karl
Some pump assemblies, have a hose going from the pump outlet to the top of the pumps housing where the quick connect fittings are. Did you notice the condition of this hose if you have one. If that hose splits or cracks you will not get fuel pressure.
Was the pump an entire assembly with the sending unit, or just the pump? It is also possible that you could have the wires crossed and the pump is running backwards.
Hey it has no line on the pump and it is a whole assembly with sending unit. I disconnected fuel line and had the key turned I still heard the pump running but no fuel came out. I’m gonna try a new pump.
I would table the EVAP system theory. Honestly, I think you should drop the tank and check your work. You might even power up the pump directly once you put your eyes on it to see if it actually does run. What I’m thinking is that something isn’t hooked up correctly or not fitting properly. If that’s the case, you’ll loose your fuel psi due to an internal leak. Aftermarket parts don’t always work out, especially the ‘cheap’ ones.
Keep us posted.
Hey all. Solution has been found. The cheap pump was wired incorrectly SSO pump ran backwards. Decided to get a pump from oreilies for a lot more money and it works! Also after replacing cracked evap lines my engine light is off so that’s nice. Thanks for the video Eric I will deff check it out.

Glad you got it worked out. Thanks for the update. 🙂
That’s fantastic, thanks for the update. Not to throw anyone under the bus here, but would you mind listing the manufacturer of that pump? That way it’s in our database and can possibly warn others of the same issue.
