I just put in a Gm 847 cam 1.6 RR's new lifters and pushrods. When I went to start it up initailly, the car started right up but I had to give it gas to keep it on. Well, I boke in the cam for twenty minutes and shut it down. I went to try and start it back up and it took forever to get it going. I decided that the rocckers needed to be adjusted and I even pulled of the intake to do it. When I put it back together, it didint start at all! Its on a stock tune 97 f-body. I also deleted the a.i.r and egr sytems. What the hell is wrong with this thing. I have checked the spark, good fuel pressure( plugs are fouled. My oil even smells like gas. I checked every vacumm line as well. I really need some opinions guys. I am at my wits end with this thing. I also changed out my springs to K-800's. My car is also having trouble turning itself over. My battery is kept at full charge with a charger. It is also coughing at me through the intake.

 

Any ideas anyone!

 

It sounds like your rockers are to tight.

 

Really, How can I readjust them if the lifters are aalready pumped up. I have adjusted these things three times already. I am 99.9 percent sure the cam timing is correct. I was able to start it before but now it just turnes over and fouls my plugs

 

Come on guys, Nobody know this stuff!

 

loosen them up pretty loose, not too much. Start the car, and adjust them by sound. Tighten them until each one stops ticking then turn it another 1/2 turn.

 

Thanks for the reply, I can start the car anymore. That is my problem.

 

I had the same problem with my Ford GT after cam swap, don't know how fussy the gm's are but mine started right up aswell but after a few minutes ran like crap and was a mother to start. I will be doing some major mods to my 94 Z28 and will be sure it will need a tune aswell.

WHat did you do to fix it?

 

Compression numbers? How about checking for dead cylinders?

 

I havent done a compresion check yet. How could one of the cylinders be dead.

 

I really need help guys, any ideas will be appreciated.
