I have a 97 ram sprot i just replaced the fuel pump waterpump thermostat and now all of the sudden i have a ticking sound it sounds like a lifter but i feel nothing when i feel the valvecovers i do feel the tick when i grab the fuel line that runs betweeen the 2 sides of the motor.... any ideas ?????

 

Injector.

 

Do i replace them all or just the one ? and how do i tell what one it is

 

Replace all of them?? At $70/injector, you're looking at a lot of money. If you can get a mechanic's stethescope, that will help narrow down the trouble-maker. Another cheap way is to use a very long screwdriver. Hold it against the suspected area and then place your ear against the handle.

To fix it you can run some injector cleaner through your fuel system, which I would recommend every other tank for about 10 tanks. Alternate between injector cleaner and Marvel Mystery. I had an injector that was ticking and it finally went away. I make it a habit to run Marvel Mystery about every 15 tanks and injector cleaner about that often as well.

 

Try relieving the pressure on the rail, then starting it back up. Do that several times. You could have air in the lines that is trying to work its way out. You can get a set of accel injectors for ~$280 IIRC. Hughes has got them. Summit does as well, and are cheaper than Hughes, but you will need the part # there. They will not just comeup by make/model or engine search. If you need it post back here and I will dig it up.

 

How do i relieve the pressure in the rail ?

 

Here's the procedure:
