I have been starting up the car every three or four days, so one morning I tried to start it up it did nothing but crank but no start. It is getting gas through fuel rail. pump fuse is good, new pump relay. (Help)

There could be many reasons causing the no start. If you have fuel pressure, that does not mean it is getting fuel through the injectors. Review the 2CarPros article listed below. It discusses several possible problems, some of which you have already checked. Review the page and let me know what you find.

Note: If you can, see if the engine will start using starting fluid. If it does, it is a fuel related problem. If it does not start even for a couple seconds, then it is ignition related.

I sprayed some starting fluid in trotter body it act like it wanted to start a little, but it did not run at all. Do you think the crankshaft position is the problem.

The ignition system can tell us that, do you have spark at the plugs?

Here is a guide to help you find out.
