New dizzy, so assuming the cam sensor is fine also? Where did you get the crank sensor, and could possibly be a coil also.

Sorry, but I have to ask, he could have a distributor and a cam sensor?? I thought the cam sensor utilized the old distributor location. Have you checked spark at the coil or only at the plugs? Are the plugs wet or are you checking for fuel at the fuel rail? I ask because I was recently fooled.

Why did you replace the distributor? Was there a problem before this? There may be fuel pressure, but is there power to the injectors? Kinda hard to diagnose with more info.

yes it had the problem and i took it to a shop that replaced distributer,cam sensor and crank sensor. it ran for about a week then the same crank with no fire. i replaced the coil myself and it ran for a day then no fire again. if i disconnect the neg battery cable then reconnect it will start then cut off with no fire from coil to distributer

Try replacing the ASD relay. It could be a problem. That's the Auto Shutdown Relay.

You still haven't been very clear, is it getting fuel all by itself while it's cranking over? I ask because if you have no spark and no fuel, then that would narrow down what could be wrong. The only way I have ever checked an ecm is putting in on a vehicle diagnostic, and even then it wasn't always right. You could pocket one from the jy and try it out.
