Hey everyone,

I have an 88 Iroc TBI 305 that i just installed new plugs wires and dizzy cap onto.

One of my distributor cap bolts snapped so i had to remove the whole thing which has lead to where I am.

The car is turning over with an occasional popping from the rear but wont start. I have tried so many different combinations along with putting the old stuff back on with no luck.

Im using 18436572 firing order clockwise

8 7
6 5
4 3
2 1 as my guide


TDC the rotor is pointing #1 cylinder
Plug gaps at .035

Ive tried moving the dizzy around with no luck also I tried rotating it 180. and I tried rotating the wires 180. No combination is working.



Any insight appreciated.
Thanks
Mark

 

That should work. Is there voltage at the coil primary? Is the four-wire flat connector clean and fully seated? Are the new plugs fuel fouled?

 

Maybe what the OP thought was TDC on the compression stroke, was TDC on the exhaust stroke? Just a thought, especially since your getting a 'popping' out of the exhaust...

 

Thanks for the replies,

I managed to get it going, after switching wires around again i found the #1 starting point was a post to the right. I cleaned the throttle body and put all new gaskets in it and cleaned up the IAC and TPS.

While doing the fuel filter a line broke, so that is my next ordeal.

I was still experiencing a high idle, it is reading at 2000 and fluctuating down to 1500. I don't have high hopes on the new fuel filter helping.

Any insight there would be helpful.

Thanks
