New to forum but need help!

98 Dodge Ram 1500 5.2l. Truck was stalling when coming to a stop. Replaced tps but a day later it stalled again. Now it wont start at all but turns over. I keep reading crank sensor but people have replaced that and it still doesn't help. This is my wife's truck so you can imagine the pressure I'm under to get it running again. Help!!!

Fuel pump????

 

[JohnnyBlazer82]

Its getting fuel and I can hear it kick on before I try to start it. Pushed the valve on fuel rail and fuel sprays out of it.

 

[dodge dude94]

Cam and crank sensors don't generally throw codes when they die, they just kinda up and leave.

Put the wife in her truck. Push the truck out to the street. Get a new one with a running truck.

If you have fuel pressure and no spark, crank sensor is a good place to start.

 

[Rustycowl69]

you didn't mention auto Trans or not. could it be the Trans converter still locked-up?

 

[JohnnyBlazer82]

Update-- Its automatic transmission. Well I gave it a tune up plugs,wires,distributor cap,rotor,pickup coil,ignition coil. No spark!! Plugs were extremely bad though. Tomorrow its the crankshaft sensor smh. And its guna be raining yay!! Hope this is helping somebody.

1/2" socket if i remember correctly. I go over top of the passenger side of the intake manifold while others go from the bottom.

 

[JohnnyBlazer82]

Yea that's what im going to try. Seen a YouTube video where this guy went in through passenger fender well. But you have to replace all the plastic rivets that hold the mud guard on. Guessing itll be a feel and touch process from the top huh

No power at the ignition coil. Got told that's a sign of crankshaft sensor failure. True?

 

[crazzywolfie]

you will only see power at the coil for a short second or 2 when you first turn the key on. then the computer waits for the sensors to give it the right signals before it will turn the asd relay on which powers the coil and injectors

 

[JohnnyBlazer82]

So if the crankshaft sensor is not sending signals then no power to the coil? Im not getting any spark from ignition coil at all when cranking the engine

 

[crazzywolfie]

ya that is how it works

 

[dapepper9]

Yep. I'd the crank sensor goes out and the pcm isn't receiving signals from it, it will keep power from the coil effectively shutting off spark. It will also keep your injectors from firing. It will just crank.

 

[JohnnyBlazer82]

Ill be replacing it after work today. Ill post my results and say a prayer for me lol. Raining too damn it

 

[JohnnyBlazer82]

Still no spark!! Not sure what else to do.

 

[crazzywolfie]

it might be the cam position sensor. i think those 2 sensors are the ones that effect the fuel/spark

 

[JohnnyBlazer82]

I dont think there is a cam position sensor. If there is where is it located. Sure that's not the pickup coil?

 

[crazzywolfie]

the cam position sensor is in the distributor
