Cranks but no spark on 1994 Dodge Ram Van B250

My 94 ram with a 318 turns over but i am getting no power to the ignition coil. does this voltage come from ecm, asd relay. there is no fuse box under the hood. i already was not getting a signal from ecm to fuel pump and keep blowing ecms so i hard wired fuel pump to battery. could i be having ecm problems again. i am gonna the last ecm back in and see what happens.

Goes through the ignition switch first, I see at least 6 manufacturers make this switch so it must be a common problem

Valleyautotech thanks for your response, my problem has changed now it won't turn over,there is no dash lights, no radio, no check engine light. I assume my problem is the ignition switch. My question is, is the ignition switch the actual key tumbler you turn to start the car.

I have a 1994 dodge 250 van with a 3.9 engine. My question is, the engine crank but won't turn over until the relay under the hood makes a tapping sound for about 6 seconds, then after it stop the check engine light comes the van start right up.

My 94' B250 also does this. It won't start until I hear the tapping/ticking sound. It would only take about a couple tries and it slowly got worse and started taking about 30mins and it eventually killed my battery and so I just haven't tried starting it so I don't have to buy another battery. But, what is that clicking noise that is so nessecary to start the van? If you figure this out and inform me of what you did to repair this problem, I would be highly grateful.

I have A 1993 B250 Van 3.9 liter, had the clicking noise and during the clicking the engine light would flash until the clicking noise stopped and then it would start. It would not get voltage to the coil until it stopped clicking. Then it got worse and quit starting all together. So I replaced the brain.It fixed the issue but the brain went out for a second time after about 3 Weeks, replaced it again and it went out again but did not do the clicking noise, just went out going down the road and cant get voltage to the coil again. Something is causing it to go bad or is just because its remanufactured. Each time I replace the brain it worked for about 3 to 4 week and it goes out again. I was told the brains are obsolete and can only get remanufactured ones. Cost is about $250.00. Any other ideas anybody?
