The engine will crank but not start. I have a good blue spark and a steady 60psi fuel pressure. Is it possible to have good pressure and not get gas getting to the cylinders?

I have good fuel pressure, 60 psi and a nice blue spark, but the thing will not start. How can i tell if the injector is fireing. I don't get any codes.

Check for 12 volts to them from injector fuse on the positive side.
You can use a noid injector pulse test light to check for pulse.
Pull plugs and see if wet or dry on end.
If dry give it a shot of carb cleaner.
If it fires on carb cleaner you have a fuel delivery problem.
Also make sure it has spark to all plugs.

Yes check for injector pulse and 12 volts on pos. side of injector.
Will it fire on a squirt of carb cleaner.
If so it is a fuel delivery problem.
Spark to all spark plugs?
Pul, spark plug and see if they are wet or dry.
If dry you are not getting fuel.

I hit with some starting fluid and it fired up. I think I've been chasing an elctrical problems when I really have a fuel delivery problem. I had the spider replaced 50k ago. I don't think they put in a nut kit. I'm goin to take a look. How long should spider assembly work.
