....really need help with this car really getting on my nerves.... Car just cranks and cranks and cranks....i can smell the gas.. And im getting spark......PLEASE HELP....ANY SUGGESTIONS

 

I would say clean your grounds and add a 4 gauge ground wire from the factory ground to a bolt where the engine meets the tranny. You can get it at wal-mart or any auto parts store.

 

Check your crank position sensor maybe.

 

Sounds like a plan to me... Definetly will try

 

Apparently the guys who did the swap did that but i may go put new ones on just so i can know they r good

 

gl with your fix and keep us posted im curious to see what the problem is, im sure you will figure it out sooner than later

 

I definetly hope so...

 

Hope you get it running, that max is gonna be a rocket. You'll be able to race anything in that car. In that 45 mins did you run the car hard? It could have blown something if you reved it high while the car was cold.

 

I sure hope so the people that was doing my swap had it running, they showed me a video and i can see that it was my car that was running, and they said they just pushed it up to around 60mph so idk.....its like i cant stop because im already money wise deep into the swap but yet this issue is killing my hopes of it running.

 

Check the harness grounds, the ones that used be on the intake manifold. Make sure those are connected good (not to the plastic valve cover).

 

Yep they are definetly on the actual manifold......

 

How good were those machine shop cam adapters? I used stephen max adapters and the dowel pin broke causing the motor to die (no start)
when i pulled the motor the valves were bent in the rear bank timing jumped, hope its not the case for you. spray starter fluid in the throttle body crank the engine if it backfires real bad 9 out of ten times its jumped timing issue from what ive experienced .

 

Yeah i think it might have jumped timing

 

Sorry for the super late update but nothing yet havent really touched the car cause ive been so frustrated with it and gotta get more money to start tinkering with it

 

Bump for someone with some experience to help him out

 

The cam adapters worked in a previous 3.5 swap we did.

 

My guess as well.
