My 1st post of the same subject

Summary: rescued 75 with L-jet: HAM repaired heads, 9550 cam from Type 4 store, All engine harnesses from Bowlsby, 96mm pistons from type 4 store (1911cc), Injectors cleaned by Cruzin Performance...(twice), engine sat for 12 mths while I worked on rust from sitting for 10 years, etc...

A couple weekends ago I went thru EXTENSIVE troubleshooting with Timothy_ND29 (huge thank you (IMG:style_emoticons/default/beerchug.gif) ), but the engine would not fire. That is the above link....

We ended up determining that my fresh injectors were clogged cause they sat for 12+ months. CruzinPerformance "woke them up" last week and they arrived back here today. I don't know what else to test: EVERYTHING operates, EVERYTHING:

1. 35+ psi fuel pressure
2. Starter turns engine with the key.
3. Noid lights at all injectors LIGHT
4. Spark plugs at all plugs SPARK
5. Injectors squirt (tested 1 and 2)
6. Valves actually move (I had to know it the damn thing was moving on the inside)

Here is the big one: After installing the fresh injectors, I did hear a slight fire, or poot of a backfire. Then nothing. I took the air box off and sprayed starting fluid in the intake while trying to start and STILL NOTHING. (IMG:style_emoticons/default/hissyfit.gif)

Question 1: How much spark do I need?
Question 2: How much squirt do I need?

Both happened, but they seemed weak, or small.

Need more help, I feel like the doctor that left a sponge in his patient.... (IMG:style_emoticons/default/confused24.gif)
