car wont start

My car has a new dizzy, has good compression and fuel pump works. It has strong spark I checked the main relay and all the fuses, and the ECU is NOT throwing any codes. When I try to start it, it back fires and gray smoke comes out of the throttle body.

...i need some help

check your timing.

The car was running then just stopped. I checked the timing belt. it is in good shape and hasnt jumped any teeth.

check your fluids, you might have siezed the engine

I checked the fluids, gots plenty.

Check your firing order. Is is MPFI? Yous might have fuel coming from the fuel pump but all the injectors might not be working, so check each injector.

I got a DX with DPFI. How can i check the injectors

At work i have a probing sethscope i put on the injects, just use a long flatheaded screwdriver, put it on the injector and put your ear on the screwdriver. An injector will make a very fast ticking sound as it pulses.
