Does a 2001 dodge 5.9 diesel have a starter relay

The fuel relay will activate for 3-5 seconds every time you turn the key on. It should not keep the engine from cranking. I have seen problems with the ignition switch that will keep the truck from cranking. Make sure that the battery connections and clean and tight. Check to see if 12 volts are getting to the starter when you try to crank it. Hold the key in the start position and while holding it, strike the starter with a hammer. If it starts , replace the starter.

what size engine ,what model dodge ? Pick - up ram 1500 etc.... Just because a relay clicks doesn't mean it can pass current to the starter ,also the starter could be no good. Viewing a wiring diagram an testing the circuit with a DVOM - digital volt ohm meter . Also check battery cables an connections using voltage drop testing .

start by checking the starter relay.it should make a click when you turn the key.if not the relay may be bad. if it does click you may have to change the starter.the tarnsmission range sensor will also cause this problem.

Okay, If this noise happens when you turn the Key to start, your Starter Relay is bad. Now the other possibility is the Glowplug Timer. When you start a Diesel there is a pause in the initial cold start. You turn the Igniition Key to Run, then let the Glowplug Timer cycle. This cycle sound will be a series of clicks which also may cause the lights to dim.

The glowplugs absolutely must warm up to start a cold diesel engine. There should be a light on the dash which either goes off when the glowplugs are ready or a light will turn on when they are ready. It is only after that activity that you will turn the Key to Start.

Since Diesels take more power to Start, there are 2 batteries. As with a single battery system, every connection must be clean. If the Glow-plug Timer is working and you only get clicks by turning your Key to Start, check the things I said earlier. Your Starter Relay and the big cable connections.

If after all of that, the engine will not turn over and only clicks, jump the Starter Relay with 1 cable from a jumper cable set from the Positive Battery cable post to the Starter Relay on the Starter wire connector. Make sure the truck is in Park or Neutral. If the Starter jumper cable sparks and the Starter does not turn, the Starter is bad. If the Starter spins it confirms the Relay is bad.

I hope my Solution gets you going and that you consider this helpful.

Check the solenoid on the starter, it's common for them to go bad with just the symptoms you state.

Assuming you replaced the solenoid with the starter, it may be the relay. If the relay is not making a good connection, it might have trouble throwing the solenoid. The relay should be in the relay box under the hood. You can break the relay open and watch it work while someone turns the key to verify the problem.

Since you know the starter is good, now have the alternator and battery tested. If these are both good (if either or both are bad, obviously replace) then try replacing the starter relay; this will prevent a car from even turning over.

Also, check all starter fuses, iginition fuses and relays.

Q: Does the engine turn over?

Q: Does the engine start, then die, or just turn over?

Q: If it turns over, does it sound weak, or does it sound strong, like it's trying to start?

Q: Have you tired jump starting the truck? If not try this: if it starts and stays running, pull both battery terminals off. If the truck dies, replace the alternator. If it stays running, you may need to replace the battery. Look at the battery and see if there is a date sticker on it to indicate when the battery was purchased (or manufactured). (If diesel, have both batteries tested). If diesel, if jumpstarting from one battery doesn't work try the other one. Also, if diesel, make sure there is at least 1/4 tank of fuel as some diesels won't start if very low on fuel (pump does not reach very bottom of tank and will not syphin fuel in).

If gas/diesel, and it turns over, turn the key to the on position and have someone lean down at the back side of the truck (driverside) and listen for the fuel pump to engage. If no noise is heard, consider replacing the fuel pump. Inquire with an auto parts dealers as to whether or not this truck is equipped with a secondary fuel pump (usually located mid-way on the chassi).

The relay on the starter may be going out. may have a dead spot on the starter. have the starter replaced.

relays are common on dodges, go in fuse box, pick another one such as horn,a/c one that you dont need to run but know is good and swap it out. try that, it could be the ign. switch too, neutral saftey switch on a auto, and clutch safety switch on a manual. make sure nothings jammed underneith clutch pedal also and your pushing it all the way down. check for dirty battery connections to. good luck!

check battery first if ok check starter
