I read the manual and narrowed down the problem (from last weeks thread Really hard to start and lots of unburnt in the exhaust) to the secondarys and the fuel regulator. sent off the spar secs to get cleaned and they both came back 848cc and 852cc (now installed), ordered a fuel regulator (now installed), checked the coils for resistance while out and they checked out ok. fixed oil leak at the oil pedistol. Re-checked all vaccum lines and check valves put everything back together. the whole time I left the battery off and went to start it and it flooded again. de-flooded and tried again, it tried to catch once and then flooded again. we cleaned the plugs before reinstalling with carb cleaner. she still wont start! I'm running all 9's with new wires, new fuel filter, pvc valve, dp,02 sensor, fuel regulator, new primaries from gotham and a new pulsation dampner. Can anybody give me an insite as to whats going on???? I'd really like to drive her again and be able to get back to work. thanks

I just had a similar problem. I had a leaky injector o ring. Are you sure you have spark? If your sure you have spark then proceed with what im going to tell you. Also once the spark plugs have been satuarated with fuel they dont work the same. So when you get to the step of taking them out smell them if they smell satuarated then change them. Here what you can do. Pull the fuel relay and the fuel fuse in the cabin. Take off the UIM and take all the spark plugs out. Disconect the three plugs going to the coils then turn the engine over a few times to clear out all the fuel in the motor make sure no one is standing around becasue it will gush out pretty quick from the holes if there is some in there. Now with the UIM off make a jumper wire and jump the wire from the positive side of the battery to the fuel relay spot and connect it, make sure its a large gauge wire or it will get hot and not hold good voltage. While touching listen in the LIM ,which should be open, for any fuel leaks . My whole LIM filled up with fuel from mine. If everything is holding presure and there are no leaks then put everything back together except for the fuel relay and fuse. Fire it over a couple more times just to amke sure everything is burnt out. Now connect the fuel relay and fuse and try to turn it over. You might have to give it a little peddle until it catches. Good luck.

all injector o-rings and injector craddle gaskets have been replaced with mazda oem. all injectors are new(primary), or cleaned (secondaries). I'll give it a try. I was thining about getting new plugs and going stock this time 9's and 7's. And seeing what happens I noticed that when we test the plugs for spark the spark isn't on the tip, but rather inside of the plug near the porceline of the center electrod. anyone ever heard of the igniter going out? could that cause a weak spark? and lead to flooding?

Can i ask,,,have you done a full unflood and tried adding a little oil to the bottom spark plug holes to help build compression. (beleive me ive had a lot of experience with unflooding if not done right it wont start,, could try some new plugs,, spark should be at the top of the elctrode, not down near the pot)

I've done the full unflood. I'm going to buy new plugs 9's and 7's. the 7's should be alright with my mods right? I've never heard of putting oil on the plugs, i figure that'd foul up the plug.

..... i ran out of gas on my drive way and.. then added gas and the car wouldn't start..... added MORE gas. .nothing at all... so I pushed started.... it was fine after.. if you can try that.. if the car turns on.. keep it on for a min... (while) then shut it off and try to crank it... can't hurt.

never force/push start a car that fails to start :/
