SidWell Posted May 18, 2008 Share Posted May 18, 2008 The engine will fire for about one or two revolutions while cranking then not fire. If I keep on cranking, about 5 seconds later it will fire for one or two revolutions. In other words in about ten continuous seconds of cranking it will fire at least twice. I am not sure what to make of it. Any ideas? Quote Link to comment Share on other sites More sharing options...
Matt Cramer Posted May 19, 2008 Share Posted May 19, 2008 Could be a lot of things. First check your timing. If that's OK, then you'll probably need to adjust the cranking pulse width. See if your plugs look wet - if that's the case you probably have too much pulse width. Quote Link to comment Share on other sites More sharing options...
SidWell Posted May 19, 2008 Author Share Posted May 19, 2008 I had my girlfriend crank the car while I looked a the firing with a timing light. The car fired at about 11 degrees before tdc. Isn't that about where it should be? I will look at my cranking pulse with when I get home tonight. What would you recommend for the PW? Last night I cranked the engine for about 15 seconds. It fired like clockwork about every 3 to 5 seconds for about 2 revolutions and then died. I guess I will need to find an oscilloscope to get much further than just tweaking settings. I am using code V 2.88 on my MSII V3 board. I have a Ford EDIS-6 CAS system and a Mopar spark coil. I have a WB O2 sensor in the collector of my 6-2-1 exhaust. The intake is a custom built 6 butterfly manifold. The engine ran while using the EDIS system and stock intake/exhaust system. I am using the current limiting resistors with the stock 2.7 ohm green injectors. I have the flyback circuits installed on the V3 board.

niner11 Posted May 20, 2008 Share Posted May 20, 2008 Total stab in the dark.....is it possible that power to MS is interrupted at some point during the cranking cycle. I had a situation where the car wanted to start while cranking but when releasing the key I would lose power to MS for a split second and the car would not start. So, are their any resets during or right after cranking? Total long shot but it might be possible. Chuck Quote Link to comment Share on other sites More sharing options...
flames_187 Posted May 20, 2008 Share Posted May 20, 2008 i turned my pw down to 2.5 @ -40 degrees F degrees F and .1 @ 160 degrees F to help from flooding the engine while setting timing. I also took out the spark plugs and wiped them down (soaked in gas). It sounds to me like your engine is flooded with gas or i should say the spark plugs to be more specific . I was having a similar problem well i get idle now but i had to set my trigger offset to 11 (using timing light) which was confusing since i quite dont understand trigger offset. is 11 btdc ok? p.s. good thing you had your gf doing cranking the car...i had a remote trigger hooked up to the battery and all of a sudden it started and sounded like crap so i had to rush and plug the ignition wire in...lol...good times.
