LT1 Start up Prob's
 

I got a 96 Formula that take numerous cranks to get it to start. Once the car starts the car runs fine. But you turn it off then try to turn it back on and it wont. You have to keep turning it off and turning it on to finally get it to restart. It will always crank though. I have checked injectors, spark, fuel pressure. When the car doesnt start all it does is crank. The injectors dont come on. I checked injectors with a injector lamp thing. Can you all help.

Have you checked to see if the pump primes the injectors, ie run for 10 sec's

I would try a fuel pressure gauge in the line to se if you have enough fuel pressure first
you need 35 to 45 psi to start an injected car. If that`s not the problem, turn to spark
