no spark distributor

[nissan4x4]

i have replaced the coil,distributor,plug wires,ignition module,but still the coil has a strong spark but when it gets to the distributor it is weak and orange and the pathy still does not start.

I just had a similar problem to yours after my engine swap. I had some vacuum line issues which ended up fouling the plugs. At first it would run, not great, but it would drive around the block ok. While I was t'shooting it and trying to adjust timing and idle it would bog out then it finally just wouldn't start. I pulled the plugs and cleaned them (so I thought) and it still wouldn't fire. I thought it was the ignition module too so I bought one and that didn't help either. I finally pulled the #1 plug and laid it on the radiator bracket and looked for a spark when I cranked it (you have to be creative/dangerous when you're doing everything by yourself). No spark. I pulled a plug from my old motor, hooked it up and got a spark. I tested each of my "new" plugs that way and every one was fouled to the point of failure even after I cleaned them with carb cleaner and emory cloth. Go figure.

I think I was getting too much unmetered air into the manifold which caused the air/fuel mixture not to burn completely so after a while, the unburned fuel allowed the carbon in the exhaust to coat the plugs. Either that or it was all the chocolate syrup I poured down the TBI to clean it.

Anyway, if you haven't visually tested to see if you're getting a spark inside your cyliders, I'd check it.

i'm not actually taking the spark plug out of the cylinder i use another new one i had laying around.it has stumped me i'm about to call a pro to come look at it. it's just baffled me ive replaced everything checked the wires nothing,could it have somthing to do with the side marker light not working? thanks Ty

I hate to ask stupid ?s but are the plugs gapped right and all the wires in the right spot? Could the dist be defective?

plugs should be gapped right and distributor worked before pulling.

It seems like one of the new parts could be faulty, maybe the new ignition, or a bad connection on the old wire? I did have a new set of wires with issues once, got a different set and worked just fine. Maybe it could be the timing? Have you cleared the codes and checked them again?

ive changed the plug wires no difference i got a code 21 once but it went away now i get code 55 no problems. i dont get it, is there any fuses to the distributor because the problem happend fast the pathy was running shut it off for maybe 30 min. went to start it nothing just turned over.

Weird. Is it possible you just got a bad cap? If the dizzy is turning, it's pretty simple.....spark in, distributed to plug wires. THe electronics within the distributor aren't even in the loop at that point.

ive changed the cap from my old distributor to the new one then back again no difference.
