1995 b2500 conversion , any help would be appreciated . replaced the ecm a few times only to have now the fuel pump voltage drop out and no pump ??

 

Why was the ECM replaced?

Does the pump prime? Will the engine run at all?

 

the engine would start and running then die ,then start then die ... got a reman ecm and drove it a couple days (ie) 200 miles . return the reman purchase a another and this gremlin showed up . sent in the veh ID # on original ecm because they said it had to match for camper conv . , now when i turn on the key to start the engine initially the pump comes on and stops and voltage drops out , wont run fuel pressure wont build . >? some ive asked say the ground is insufficient but not having wiring diagram i can not figure out which is the ground . or even understand why this is happening . should have been a plug and play ecm .

 

See if you can find wiring diagrams here. Check your ground.....
