overheated now won't start
was driving the other day normal driving about 65mph my temp gauge read normal suddenly it spiked to the H and died, I towed it home it blew the head gasket for sure is blown (the oil looks like chocolate milk) but it will not start it sounds like its trying but it will not, I checked for spark on each plug and I have it, I can hear the fuel pump prime and there is pressure in the rail, I checked the ecm fuse and its good I replaced it anyway and still no luck, could my ecm have died?

Re: overheated now won't start
If your head gasket is blown, there could be oil, coolant, or both in the cylinders. As the pistons move up and down, they’ll be splashing fluids all over the spark plug. If that’s the case, there’s no way it’ll combust.
Furthermore, if you did somehow manage to start it in that case, there’s a very strong change of hydrolocking the motor, and that usually means a bent rod.
So, please, don’t try to start it until you’ve drained the oil pan, pulled the top end, cleaned everything out, and reassembled with new head gaskets. Good luck!

Re: overheated now won't start
I don't plan on making any mods except to paint it, I got the engine back together and everything seems fine but its still acting up when starting had a friend check it out and he said the fuel pressure regulator is most likely the culprit so I will get on that asap
