I'm hoping someone here can help me out with this, it doesn't make any sense to why it won't start. The car runs a factory E9AF ECU with a Anderson PMS and a MSD 6AL. Car has spark, fuel, air and compression. It ran for 15 minutes then I changed the oil and now nothing but cranking. I've talked to MSD, Anderson Ford and Lidio and they are all baffled to why it won't run. I've check the coil, ign. Module and computer on other cars and they all worked fine. This has been going on almost 4 weeks I did get the car to start a few times one day and it ran for 15 minutes but the next day I went to take it for a ride it started up and ran for about a minute and back to just cranking with spark, fuel, air and compression. I'm baffled like everyone else and running out of time to make it to the track. Hoping you guys can help me out

Thanks
Mike
 
What distributor is being used? Have you taken the PMS and 6AL out of the equation yet and just ran it on all ford electronics?
 
Those distributors are junk, along with the TFI modules they come with. Pull that bitch out and put the factory one back in, with a Motorcraft TFI module. If you have spark, fuel and ignition then you should have fire. If you have all 3 of those and nothing then there is probably a timing issue with the distributor.


Did you check to see if there is spark being distributed at the spark plugs themself? The coil may be firing but not necessarilt being distributed properly
 
Not flooded but will if I crank it long enough lol. Injectors are spraying. By passing the MSD is my next step and only thing I haven't tried yet. I tried a different MSD 8456 dizzy and still wouldn't run. Have spark to all the plugs. It has to be electrical of some sort. If you have spark, fuel, air and compression in all theory it should run but it won't, it doesn't even sputter, pop or backfire just cranks. I've checked timing and it's fine
 
its' electronic. so back to stock ignition and dizzy

MSD stuff is mass produced junk. never had good results with it.
 
I'll try to find time this weekend to bypass the MSD, if that don't work I'll be hitting you up Krazy-k
 
No :( I just bypassed the MSD and still have a no start. I checked for spark and yes I have spark with MSD bypassed
 
Plugs are wet after cranking and no still no start at WOT, but thanks for the ideas. I'm thinking a ground too but to chase one down would be like finding a needle in a hay stack :(
 
Did you change to a heavier weight oil? does they car have a hydraulic roller and adjustable roller rockers? I suggest doing a compression check and verify you got some cylinder pressure, take the cap off the dizzy and crank it over, make sure the rotor is turning. Were there any other changes done when you did the oil change? Anything, wires, plugs, fuel filter... anything?
