Lo Boost
-the RPM stage one is on.
-the timing is set to 0 with the brown wire disconnected, did this by cranking the engine with the timing light hooked up and moved the distributor accordingly.
-The gas tank has 10 gallons of 100 octane.
-I have 34lbs of fuel pressure with the vacuum line disconnected.
-The stock chip and 2 bar map sensor are installed.
-I have some AC delco plugs gapped to .030" in the engine.
The weird thing is when we changed to the stock chip and the 2 bar sensor, (had the Ultimate chip and a 3 bar) add propane to the engine and it started up and ran by itself for a minute, we removed the propane and it ran good by itself but we shut it off because we saw smoke and wanted to make sure nothing was leaking, which nothing was :rant: .
I would like to take the time to say that my truck sounded so clean and smooth. It sat at 1400RPM and wasn't sputtering or anything I hit the gas a little bit it and the engine reacted quick and responsive. It sounded simply amazing, just and smooth rumble.
So now the engine just turns over and doesn't start unless we add propane, when we add propane it just sputters tries to start but wont. later tonight I'm going to get some noid lights from my work and check the operation of the injectors, I think they may be bad/dripping, fouling out the plugs causing it not to start. (one of the few things I haven't replaced in the fuel delivery system) and ideas??
On a side note I have checked a couple other thing listed below.....
-Great oil pressure
-Spark plugs are wet after cranking, fuel pump is priming and operating good.
-150 compression across the board.
-Both ECM fuses are good, I have been pulling the fuel pump one to prevent fludding the engine.
I have checked much more stuff but I don't remember right now......
