Just an FYI for anyone interested--

To make a very long and difficult story short:

My Crossfire was taking a long time to start. Starter spinning fine, but not catching for about 5-6 seconds. Didn't happen when cold, or when warmed up, only after sitting for about 2-4 hours.

Dealer diagnosed as a bad fuel pump, replaced under warranty.

I don't think this is the same as the mystery no start issue. Anybody have similar problems? I searched fuel pump and it doesn't seem like a common problem.

 

did your car crank?? my keeps cranking but no start when the engine is warm (not hot). It starts in cold and when the engine is hot just fine.i also did get a check engine light but it goes off after few good starts.

 

Yes it cranked just fine

I should say it didn't happen when cold or up to normal operating temperature. Only after sitting for a few hours.

Sounds like you have the same exact problem. I'll let you know if the new fuel pump fixes it.

PS: I never got a check engine light

 

i might have the same issue than. i don't understand if it was a fuel pump than it wouldn't start in cold or when engine is hot. it always happens when i leave it for approximately 45 min to an hour and than i try to start it.

 

I know, it doesn't make sense to me either, but the tech said it was the fuel pump. I get it back tomorrow, I'll update you on the progress.

The fuel pump makes sense, but not the temperature difference.

 

ok just give it a few days of running and see if it does it again and report back please. yes i did get a check engine light and before i take it to the mechanic to diagnose it the light goes away.

 

Banej, that sounds like the crank positon sensor setting off the CEL. I had a similar issue and used a OBDII reader to pull the code. P0335 I believe. The crank position sensor CEL will clear if the car starts up fine 3 times after it trips.

Figures, doesn't it? I had trouble getting a dealer diagnosis. The first dealer "couldn't replicate the problem". Second dealer I showed them the problem personally. I left the car there for a few hours and came back and showed them exactly what it does. You may be lucky if this fuel pump trick does it, you can have some ammunition when you take yours to the dealer

 

MikeR, does the crank position sensor fault allow the car to crank? I was under the impression that the crank position sensor issue made the car not even crank. The issue I am having is the engine cranks at full speed, but does not catch, as if it has no fuel.. Also, I never got a CEL.

The main reason I ask is because if this fuel pump doesn't do it, I want a backup plan to talk over with the dealer

 

Mike, does crank sensor need to be replaced and did you fix the problem in your car? i will go straight to the dealership next time i get CEL to see if i also will get P0335.

 

yes i think you may be right because the crank sensor wouldn't let the car crank but in our case it the car cranks every time but no start. fuel pump makes more sense but i just don't get why the temperature change of the engine makes a difference.

 

The car will crank just like normal with the crank position sensor error... just no ignition... it times out and stops cranking.....

There is also a camshaft position sensor that will cause a similar no start... it is on the front of the engine.

Cool, I have backup in case the fuel pump doesn't fix it. Either way its under warranty though, which is nice

 

I have had this faulty fuel pump issue with two vehicles in the past, neither was German made. Both times the hard starting led to no starting and the pump failing completely. Get it replaced.

 

Hey Banej, I just saw your original post, sorry I should have responded to that one. Funny we had the same problem at the same time.

 

Guys, just got my SRT 3 weeks ago and have been experiencing a similar problem.

Usually though its when I shut it down to fill it up or run into the house real quick. I turn the key, it cranks, but never catches. After 3 seconds I kill it, wait 3 seconds or so, then try it again and it works!

I have read on here something about a fuel pump relay issue that is common with these cars? I believe the thinking is the relay is faulty so it prevents the pump from being primed when the key is turned to crank. By the time you crank it a second time it is primed and starts without issue.

I told my friend about this (he is a car nut) and he suggested turning the key all the way until right before it cranks and waiting for 2-3 seconds. Then crank it as usual. He thinks the pump will prime during this time and should start without issue.

Oddly, it has been working. Before this, I would get a false start half the time, now, its about only 1 of 10 times do I still have the crank-but-no-start issue.

I am used to quirky German cars, but this is beyond me. Its also disconcerning to hear all the different reasons from the dealer on this. Makes me nervous.

What do others think?

 

Ifr anyone things their CPS sensor is bad, they can be replaced fairly easily. It's a tight fit but only requires a single allen wrench. The cost would be around $70 for a new sensor and the dealer will charge about $200-$300 for it. Has anyone tried it??

 

Yes. It is quite easy. You need an E8 torx socket for the bolt. The sensor only goes in one way, so you cant do it wrong.

i took my to the mechanic the reading was Crankshaft Position Sensor Circuit. Can someone tell me where this part is located. I have the Repair Manual that i downloaded in PDF file and if someone knows on what page it is. Thanks for all your help

are there any stores online that have it cheaper than $70 bucks?? and does anyone know the part number for the Crank Position Sensor??

 

If you search and find my thread on the Crank Postion Sensor you should find the part number.

It is located on the back of the engine, drivers side, just above the bell housing. You need to take the drivers side intake off to have a nice clean look at it. The locking clip for the connector is on the passenger side of the connector. Squeeze it and pull the connector off. E8 torx socket for the bolt. Carefull, dont let that little sucker drop. It could be hard to find. I didnt have any trouble reaching down and holding it while pulling the socket back out with it. Then just pull out the sensor.
