Car will not start anymore

Yesterday, my car would not hot start after sitting for about 5 minutes, just cranked. I let it sit for 5 hours, and it started right up but blew tons of white smoke.

Drove it for 15 minutes, parked it for an hour, went to get food and it started alright. Drove down the street, parked it, sat for 5 more minutes, would not start again, just cranked. Had to get it towed.

Went down stairs this morning and it just cranks. Does not start at all, pulled the egi inj fuse and cranked for 10 seconds twice, replaced it and still doesnt start.

Does this sound like fouled plugs? Is it flooding? This car has never flooded on me yet, and this is the only time it has failed to start on me. Ive had it for about a month now. Compression readings were 5.2 rear rotor and 6.2 front rotor. (I know its bad)

If you can't get it to start by pulling the fuses it may have been severely flooded

follow that link, and do what "phase 2" says... this happened to me 2 years ago when I was a newb myself. Good luck.

White smoke is not a symptom of flooding. That suggests coolant or oil getting into the combustion chamber. Have a sample of your coolant checked at a radiator shop for the presence of exhaust gases. If they are in your coolant, you have a blown coolant seal, and need a rebuild.

I think somebody on here reported some success with some kind of liquid ceramic sealing compound, but I have no experience with that.

Flooded starts are a symptom of: low compression, or leaky (dirty) injectors.

You can also tell if it's coolant based on the smell, if it has a sort of sweet smell to the smoke, good luck.
