I have checked spark and fuel both are good... any idea's??? the car acts like it wants to start but wont...

 

fuel and spark are good eh! ok you need to stop cranking away at it now cause i can almost bet that you didnt adjust your rr's you need to do that or it will never fire

 

i was told the one i have do not need to be adjusted... Crane LT-4 RR's with studs... I f that is not the case I have no idea how to adjusted them... Anyone want to bring me to school on that one???

 

Eeek!

 

ok, i have now adjusted the RR's, now the car starts but will only hold at 3000 or above RPM's and not for long before it dies...
My plans are when i get home are to put a fuel pressure gauge on it to see what the pressure is at... What should the pressure run at???

 

Do you have any air leaks after the MAF? Are you sure the RRs are adjusted properly?

 

yea RR's are adjusted correctly a buddy of mine came over to show me how... he use to work at a performance mustang shop...

he said its all about tuning it correctly to get it running right...

so what should the fuel pressure be at???

 

If your FP is from 39 to 46 or so at idle you should be fine it should actually increase a little as you give it the gas and hold. Sounds like a vacuume leak to me, or possibly a timing issue.

 

their is no way its a vacuum leak i checked all that...

now the timming what do mean??? cam runs opti the chain was put on right for sure, i check the wires twice as well as the fuel injectors wiring harness plugs...

 

Sounds like you have the timing covered then.
Is it trowing and SES lights after it runs for a while?
Usually if there are no vacuume leaks and the timing is on then unless the TPS is haywire and the IAT is not responding it should idle fine. Try starting it then bring it down slowly to let it "settle" if it will.

 

thanks for all the input i will pick up a scanner tonight and see what is does...
