Hi guys just recently my cars doesn't want to start , it cranks and it crank but when it cranks it backs fires and the neigbors don't really like it since it sounds like a bazzoka .. I have change all crank and cam sensors and all ingnition coils I have cheked for vacum houses and everything seems to be ok .. I do have a new battery and ground kit , it seem to do it more now that it is cold cuz it didn't do it as much when it was warm but still was hard to start but it didn't back fired . but when it starts it runs so smoth and with plenty of power and if I turn it off and try to start it it cranks and it backs fires .... it seems to get floded cuz I smell raw fuel and the sparkplugs are black but dry and it seem to be runing rich .. is there a ignition spark module somewhere ? or can it be the ecu .. i have a 95 manual max ..

thanks for the help !!

 

Try a ground wire directly from the battery to one of the starter's mounting bolts.

 

Thanks for the reply pmohr ... I have done that I have change all coil packs new plugs change all sensors cam and 2 crank .. the ecu and the same thin happens it cranks and backfires it cranks and backfires eventually if the battery doesn't die it starts and it run fine but some times it will start but never in the first crank it takes at least 2 or 3 cranks before it starts .. I have read almost all the trads on hard starts but my situation is different cuz I think it is not a ground problem since I have a grounding kit .. I drop in a 1998 infinity engine and since day one it never started the first crank and my orinal engine start it barely turning the key and it would start right up .. is getting cold here in MA and never mind that I need my car for the two jobs I have ..
any help will be greatly apprecianted ....

 

the only codes is giving are p0180=fuel temp sensor , p1335=ignition system misfire,manfacurer control, p0443=evap emission control system purge valve c fault ...
