I gave it a go last night.. Got the pumps at constant 12V, primed lines, TRIPLE checked everything.



It spins fine. Nice pulses.. Just no fire. Everything seems in check.. no leaks, nothing like that.. I'm guessing it has something to do with either the PFC or the FPR. I'll hit at it more tonight.. If anyone has any ideas throw me them!



Question: What kind of timing should be on the leading and trailing? It's at -25 for both.. I really don't know much about the PFC.. I thought it had base maps?? I found how to set the secondary injector size.. But it only goes up to 1500?? Sorry to keep bothering you guys.. If anyone can help me get the computer setup it would ROCK.

Check for spark. Get a spare plug laying around plug it in and ground it and crank see if you get a spark. If you get spark, look at fuel. Make sure the relays are working and look a FP.

Is the ignitor plugged in?



Is it even trying to start?

Doesn't seem like so... Just turns and turns.. No sputtering or anything..

That timing seems awfully retarded. I think it's normally around 0 ish for cranking.



But the PFC only shows values in comparison to some base value you can't see without the Power Excel / Datalogit software so it might be right anyway.

You will need a datalogit to change the fuel injector size to a 1600 ro 1680 setting. The commander will not adjust that high. Have you spun it with the plugs out to make sure your fuel injectors are firing? or you could use a noid light to check and make sure that they are firing.



On the plug side, test to make sure you are getting spark first off.....if so, check your timing and split to make sure that they are firing at the right time.....not sure what the right time is though.



Also, when I first had to start my motor last fall, I had to ATF the motor a few times to get some compression up when I cranked it....that jelly substance they put in the motors to keep the seals lubricated makes it hard to start....you have to burn all that crap out......and after a few mis attempts of starting it, I had to unflood it a few times, and then try again....after a few hours she finally kicked over.

I'll run through all that tonight. Thanks!

hope your exhaust is point out of the garage if you are going to ATF the engine...btw that boosts compression like a charm

dats what i was gonna suggest, cause its the same thing that happened with my car. it made a sound when being cranked as if it didnt have enough power. ATFed it for a while, and then it turned on...
