I have a 99 head with 02 block with all beta 1 sensors and 99 ecu

 

I feel like crank sensor is faulty having an 02 block with a 99 crank they are to bit different so it make me think that could be something to look at because I have here a diagram that's telling me the ecu may not allow its self to ground due to a back cps because it basiclly can see the crank spin so half of my ecu is dead

 

Hey guys. If it is sparking it is not a sensor fault, that means that the ecu is getting a reading from the sensor and is firing the coils. It wouldn't do this if there was no crank signal.

If it starts to fire with engine start then it is a fuel problem.

You have checked there is fuel pressure correct. Please double check your feed and return lines are not back to front. I have seen this many times on engine conversions.

If that's ok then it has to be an injector fault.

Check that all your injectors have a 12v feed with ignition on.

If you have that try checking your injectors are getting pulsed. Put your test light clip to positive and poke the test light to the negative side of your injector while cranking it should flash.

If its doing that your injectors will either be blocked or seized.

 

You *can* pull the rail and let it spray into a bucket to test injectors, but it kinda sucks.

 

Yea easy test do this ^^^^^^
