I've been asking about getting this 90 ram 50 running. I have totally redid the inside with new carpet and seats, cleaned and replaced all the plastic and got all the fuses and lights working. The new ecm came today and I put it in. checked the coil for spark and yea I had spark at the coil. Hooked the coil to the distributor and tried to start it. No joy. Tried several times hoping it was just waiting for l to get to the injectors. After 3 or 4 tries I retested the coil. Now I have no spark until I release the key from the start position, then it sparks one time. Did I ruin the new ECM. What''s next, only code now is 15. checked the plug and all is correct.
