can you troubleshoot the ECM?

What is your question?

I have replaced the coil, cam position sensor, crank position sensor, fuel pump comes on momentarily when the ignition is in on position, checked the compression, checked all fuses and relays. Still, no fuel pressure and no spark. I've been told the problem is in the computor. Tired of spending money on parts that won't fix the problem. How do I see if the ECM is bad before I buy one.

What makes this problem better or worse?

Engine turns over great, won't start

How long has your 1994 Dodge Dakota had this problem?
