after all the time and effort I put in to doing the timing chain and all of that. I had to replace the plugs, now almost a month later my truck is doing the same thing. I get spark from the wires to the plugs, but no spark from the plugs. Could I be burning out the plugs becuase of the headers? If so do I need a special set of plugs? Or is there a bigger problem that I'm not seeing?:grrrrrr:

What color is the spark at the wires?
And when you say wires do you mean at the boot where they go on the plug?
Or at the distributor?

It is possible you are not getting a good enough spark to fire the plugs. Or that the ignition module is weak. coil is week and there are other things.

its blue, a light blue. I have replace both the coil and the ignition module. I get spark at the boot.

okay I just went out and checked again, it's a reddish spark and it seems pretty strong, and now i'm getting it at the plug as well. the ends of the plugs are darker then they were.

I wonder if it could be the wires? It sounds like you have replaced everything but those. And if the headers are near them it is a possibility.

Just guessing here but that would be my next step. Wires that are brittle can be cracked inside and you would never know it by looking at them and where you got spark of one color before and it is changing now that would be a good possibility.

Good luck, I hate electrical problems.

Just tossing this out there, your ground is good for the engine.(no grease on it). we'll get it figured.

ground is good, haven't messed with the wires yet, gonna try that in the morning.

 

[coldsteel1993]

checked the wires. I'm getting red spark from both plug and wire. I'm getting fuel. She tries to turn over but no go.

okay pulled the cap the contacts look alittle white, is that a problem? I had replaced the coil about a month ago, and the ignition module at the same time, I did not replace the cap or the wires, could this be the problem. It ran one day( I moved it back from the road a bit)(it ran really rough) Then the next day it wouldn't start. That is where I'm at now.

maybe the cap and rotor. this is a easy swap out andf should have been done with the plugs and igniton mod.....mike

Sounds like you are getting a very weak spark, by the color you are saying it is... try new plug wires/cap.

 

[coldsteel1993]

okay gonna try the wires and cap in the morning. thanks for all the input. As far as it being done when I did the rest, I know. I ran out of money, and forgot about it after that. I will learn sooner or later. thanks for all the help, I will post after I try this.

 

[coldsteel1993]

cap and rotor aren't the problem, She tries harder too start but still won't start.

Whatever happened. What is your mechanical timing set at?(if you can ever get it started again) Make sure your wired to the correct firing order! You mentioned changing your timing chain. Also make sure your wires are not being pinched anywhere, this can cause an arc. Last but not least the harmonic balancer may be shifting it's outter rim and causing inacurate timing marks.

Please let us know the outcome.

You still haven't gotten new wires? What are you waiting for?
