Has new tcs, new crank sensor, gets plenty of fire, the right amount of fuel pressure to the fuel rail but when when we try o start the injectors don't spray and they're new injectors. Was wondering if there was any other sensors that I could change or should I try the computer next?

 

What controls injector pulse? Is there a fuse or something that could be bad? Are you sure you got all your connections in place when you did the injector replacement?

 

Cam sensor under the distributor cap. Also known as the pick up coil.

 

Check all your grounds. Especially the one on the right rear corner of the block.
Can you feel the injectors clicking?
Check for fire to the injectors with a multitestor maybe.

 

I have checked grounds and I forgot to put the year it's an 88 u it will run as long as u r dumpin fuel to it threw the intake

 

If that pick-up coil controls injector pulse that could be it. You said you've got fuel at the rail and spark at the plugs, and it'll run if you use starting fluid in the intake. It has to be something controlling injector pulse.

 

I didn't know that the pick up coil would keep the injectors from workin may need to try that it's the only thing I have left to change I think

 

Any updates on this, I am having the same problem on my 94 Cherokee

 

change this you should be good

 

Well changed the pick up coil and still same thing
