I just bought a 2001 ram 2500 and the guy said it had no spark. After further inspection they had pretty much destroyed the distributor.. I replaced the crank sensor, coil, distributor with new cam sensor, plugs, and wires. Still no fire or injector pulse. I get a small sputter after 3-4 revolutions with the starter but after that I could turn it over till the battery dies without another. Any ideas?

 

have someone else crank the truck, while you monitor power at one of the injectors. (doesn't matter which one) See if power goes away while cranking.

 

I have a noid light on an injector and out of 7-8 tries to start it I only got one flash of the light. I messed with it a little this morning and found that the new crank sensor output wire reads 5v all the time so it's not picking up the windows on the reluctor wheel. Going to have to pull it out and start over I guess.

 

Wrong sensor? It reads right off the end of the sensor, if its even an eighth of an inch too short, it won't read.

 

I'm going to pull it out now. I think the rust etc on the mounting surface is messing with it. Going to try and find some way to clean it up.

 

Pulled out the Crank sensor and cleaned the mounting surfaces. I have fire now but it sputters and won't start. And my scan tool registers no rpms while it's turning over.

 

If you replaced the dizzy with a new one you need to have the fuel sync set.

 

Well I now have rpms reading on the scantool but they r all over the place... Nowhere near right

 

How do I set the fuel sync?

 

O nvm... Basically retime the motor. Set to tdc on number 1 and line up rotor button etc?
