Hi guys,
1995 Chrysler Concorde 3.3l here. It will not start easily and only stays running if you hold the accelerator pedal down. My brother thought it was the fuel pump so he replaced the fuel pump and the fuel filter. At first the car was not getting fuel pressure even with the new pump but after trying to start it a few times it finally primed and there is fuel spraying out of the schrider valve. However, it still is hard to start and won’t stay running.
We are suspecting the MAP sensor now…There is no check engine code for it though. We are only suspecting it because if you turn the key to ON without starting the car it makes a bunch of clicking noises at the MAP. Is there anything else in that area of the engine that would do this? Do MAP’s have any parts that would go bad and click?
Thanks guys!
Justin

No, I am sorry I should have been more specific. Fuel comes out the schrader when you open it. It does not come out otherwise.
Ok good you scared me there for a minute lol.
I don’t recall there being anything else in that area that could make any noise.
Not sure if your aware of this or not but did you know you can pull engine codes using the check engine light in the gauge cluster?
Turn the key to the run position three times stopping on the third (on off on off on) and the light will start to flash a certain amount of times.
Say the battery has been disconnected within 50 starts of the car this is code 12 using this method the check engine light will flash once then a slight pause then two more times.
Each code has it own amount of flashes.
If you would like a list of these codes i can get them for you.
Comes in very handy on the road.

Yes I am aware of that.
It shows codes: 12, 33, 55. I don’t believe any of those indicate anything wrong that would cause this. I’ve read MAPs can go bad but not throw a code?
