Question
Thanks a lot for your prompt reply!

How do I check for the relay spark? I mean do I need an AVO-meter or something? can I swap another one for this one from the relay box and see if that helps?

Best Regards Don!

Answer
I think you misunderstood when I said "check for spark".When you see if you have spark that is at the spark plug.Disconnect the plug wire,remove spark plug,ground the plug(lay it against metal) and turn the motor over .While cranking look at the plug to see if it sparking.
The first part of you comment dealt with fuel that is important to know if there is fuel pressure.You will need fuel pressure gauge to determine this(although you be able to smell it as you have cranked it a few times).
To check any electrical item you need a VOM.You can use a test light to see if there is power but the actual voltage is not known.That is why a VOM is important to use.
And finally you should invest in a manual to help with the electrical circuits.Good luck.
