No start on my 94 RMS, need help

[945frankenmaster]

My 94 RMS has been sitting a few years, i was getting strong spark to the coil but a very weak spark to the wires, i bought a 95 RMW for parts, i drove it for about 2 weeks until i decided to use it for what i bought it for and put my RMS back together, i figured the opti was bad, i swapped opti's and she still wont start, i tried using the 94 opti on the RMW and it wouldnt start either, i still have the 95 opti in the RMS, i got it wired correctly, also i tried pulling codes from the CC, i got the 00 displayed, how do i enter it to display any codes within that mode, i kno how to cycle thru all the different modes but i have no idea how to use them to see any information and i cant seem to find an explanation of how to access the information

check obvious stuff first...an engine needs three things to run; ignition, compression, and fuel.
My question to you is; How do you know that your getting a strong spark here and a weak spark there?

Check the sticky at the start of the roadmaster thread for the climate control code access

I pulled the coil wire loose while my dad turn the key and there was a strong spark, i pulled a plug put it back in the wire and had him turn the key again and the spark was very weak, i know ive got fuel and i dont have a compression gauge but it did run stronge so i doubt any loss of compression

check the plug wires. its best to check them at night to see if you have spark jumping through a hole or crack in them.
