1994 chevy blazer s-10 v6 185000. Problem started whenever I accelerated it would struggle and jerk. Then it started stalling at low speeds or "idle"driving. Would not start back up for a while. When it did start up it would stall. Changed fuel pump. New distributor and distributor cap. Now all it does is crank. Wont start. No fuel pressure at pressure check valve. What can I do?

CHECK FUSES AND RELAY TO FUEL PUMP.
HAVE SOMEONE LISTEN WHEN YOU TURN KEY ON.
I F THEY CAN HEAR THE FUEL PUMP, IT MIGHT BE THAT YOU HAD A HOSE COME OFF WHEN YOU CHANGED IT OUT.
GOOD LUCK.

Found out it was the central port injector. Bought a new 1 and it started. And stayed running until we turned it off. But there was a lot of smoke. White smoke. So we turned it off. Now it wont even crank. Its like locking up.

Pull out your spark plugs and try to crank the engine. Have someone look for coolant coming out of the cylinders. If there is, you have blown head gasets or a cracked head/block. I have a 93 1500 with a 4.3 and I did the heads, had it running and then it froze. If it wont crank just fill the cylinders with WD40 and try to crnak the engine with a flex bar. Leave it for a couple of hours, fill them up again and keep trying.
