My 2004 Sebring will not start with belt on but will without

Customer Question

My 2004 Sebring will not start with belt on but will without
JA: Sometimes things that you think will be really complicated end up being easy to fix with Chrysler. The Chrysler Mechanic I'm going to connect you with knows all the tricks and shortcuts. Tell me a bit more about what's going on so he can help you best.
Customer: Well I have replaced the coil pack the cam sensor wires and plugs and still won't start
JA: Sometimes changing spark plugs can be a challenge -- more than a few things to consider. Fortunately, the mechanics we work with have tons of experience dealing with them. Are you hoping to fix this yourself?
Customer: I tried both with and without the serpinten belt with out it starts fine but is a bit rough.
JA: Is there anything else important you think the Chrysler Mechanic should know about your Chrysler?
Customer: With it it requires someone to place there hand over the intake then remove it slowly as it starts
JA: OK. Got it. I'm sending you to a secure page on JustAnswer so you can place the $5 fully-refundable deposit now. While you're filling out that form, I'll tell the Chrysler Mechanic about your situation and then connect you two.

Is it possible that the computer is failing
Expert:  Kevin Bourcier replied 1 year ago.

the DTC is a coil , coil wire , miss fire fault . have you checked the spark plugs and/or plug wires ?

Customer: replied 1 year ago.
They are brand new
Customer: replied 1 year ago.
Plus it fires right up without serp belt but is a bit rough
Expert:  Kevin Bourcier replied 1 year ago.

is this the same problem you had before changing the plugs ?

Customer: replied 1 year ago.
It would not turn over
Customer: replied 1 year ago.
It sounded like it wanted to but would not
Customer: replied 1 year ago.
I have replaced coil pack spark wires and plugs, cam sensor so far
Expert:  Kevin Bourcier replied 1 year ago.

you can have a " carbon tracking " issue internally in the coil pack . The reduced load of not driving the accessory items will allow it to run while the belt is off but with a 4 cylinder engine that load from the P/S pump and other accessory drive components will not allow the engine to run due to internal miss fires or " double firing " 2 or more cylinders at the same time . Are the spark plug wires new ? If you remove one spark plug wire and try starting the engine to see if the engine runs differently ( better ) this can confirm this fault . try one plug wire , if no change , put it back on and try another one .

Expert:  Kevin Bourcier replied 1 year ago.

the coil pack is new ? not used ?

Expert:  Kevin Bourcier replied 1 year ago.

have you done a compression test ?

Customer: replied 1 year ago.
Coil pack brand new from auto zone two weeks ago
Customer: replied 1 year ago.
No way to do a compression test
Expert:  Kevin Bourcier replied 1 year ago.

okay how many miles on the engine ?

how did this problem start ?

Customer: replied 1 year ago.
174578
Expert:  Kevin Bourcier replied 1 year ago.

engine running fine , turned off and came back to start next time and this problem was there ?

Customer: replied 1 year ago.
One day it was working fine now I knew at this time the battery was almost completely dead it was replaced next day
Expert:  Kevin Bourcier replied 1 year ago.

what is 174578 ?

Expert:  Kevin Bourcier replied 1 year ago.

LOL , okay , the mileage . sorry

Expert:  Kevin Bourcier replied 1 year ago.

You need to check compression and the timing belt . I suspect the timing belt has jumped

Customer: replied 1 year ago.
On that same day the battery was replaced it started fine at first then a little while later they get it started it dies going thru a intersection they jump start it then it goes a bit then dies
Customer: replied 1 year ago.
Why would it start without serp belt
Expert:  Kevin Bourcier replied 1 year ago.

with that mileage and the symptom , that is most likely the issue

Expert:  Kevin Bourcier replied 1 year ago.

because of the " lightened " mechanical load . The valve timing will decrease the amount of engine vacuum required for the induction system ( intake ) to operate correctly . That is why it will start and run when you cover the intake . You are increasing the " engine Vacuum "

Customer: replied 1 year ago.
Ok I will look at the timing belt today
Expert:  Kevin Bourcier replied 1 year ago.

if the valve timing is " late " the engine will miss and be " sluggish " it is a common problem on older , higher mileage engines with belt driven camshafts

Customer: replied 1 year ago.
Is the computer possibly failing
Customer: replied 1 year ago.
I thought about changing it to a chain
Expert:  Kevin Bourcier replied 1 year ago.

no . you cannot change it to a chain . the recommended service life of a timing belt averages 80,000 miles . yours is way over it's recommended or expected lifespan .

Expert:  Kevin Bourcier replied 1 year ago.

there is no need to suspect the computer . this is basic diagnostics . check the belt . :-)

Customer: replied 1 year ago.
Yea it has the crysler logo on it so I assume it's the original
Customer: replied 1 year ago.
But it looks in really good shape
Expert:  Kevin Bourcier replied 1 year ago.

the tensioner could have failed and allowed the belt to " jump " . If the belt has ever been changed it would most likely be a Napa , gates or Daycl belt , etc .

Expert:  Kevin Bourcier replied 1 year ago.

Dayco *

Expert:  Kevin Bourcier replied 1 year ago.

It is recommended to always replace the tensioner when changing the timing belt .

Customer: replied 1 year ago.
Ok so it is original it had 130,000 when we got it from the Chrysler dealership used
Customer: replied 1 year ago.
Ok thank you please leave this open so if I have another issue related to this I'm
Not explaining it again
Expert:  Kevin Bourcier replied 1 year ago.

okay . Thank you for using just answer . When you are done I would appreciate it if you would feel inclined to give me a positive ( 5 star ) rating as this helps me greatly . it does not cost you anything additional . Thanks . Kevin

Customer: replied 1 year ago.
Timing belt was spot on
Expert:  Kevin Bourcier replied 1 year ago.

hello again . Okay well that is good news then . BUT ...... now that takes back to the need to test the compression . in order for the engine to run properly , it needs to be mechanically " tight " so 2 things . Compression test first . you need to see somewhere between 140 to maybe as high as 175-180 lbs. of compression on all 4 cylinders with no more than 10 - 15 lbs variation between the highest and the lowest cylinder . One other quick test you could do first however is to get an aerosol can of Brake Cleaner . Start the engine , keep it running at a steady speed and spray the intake / induction area while the engine is running and see if the engine speeds up and smooths out .

Customer: replied 1 year ago.
With or without belt
Expert:  Kevin Bourcier replied 1 year ago.

either . if it will run with the belt on . with the belt
