We have changed fuel filter and the sensor and it is getting fire. It is getting fuel to the bleeder valve but no fuel is going into the intake bowl. Can anyone give me some ideas?

I am being told it is probably the injecters but could someone tell me what they think.

Year? Put a test lamp on the injector and have somebody crank while you watch, if you're getting light (flashing), but no spray, injector. If you're getting no light, something in the electrical is wrong most likely. If you're getting spray, its probably a spark issue.

 

It is a 97 4x4

 

Start by checking the fuel pressure. Follow the link Spitty gave you.

 

If you have good pressure take off the air filter cover and have someone open the throttle while you look down the throttle body (don't put your head right over it, backfires are always possible), and see if the injectors are spraying (I think you can see it on a 97?). If they are not but you have a good pressure, I would do as I suggested and backprobe the injectors with a light, have somebody crank. You likely won't get any flashing, if you do its definitely injectors.

If you don't, I'd look to the crank position sensor.

 

P.S. if you don't have pressure, look to the pump. If you have spray but no run look to the ignition.
