My 97 lesabre starts runs 2seconds then dies. New fuel filter, plugs , MAF, upstream O2 sensor, and Aur Idle Sensor. Oh! New used throttle body fro junkyard. Idled on its own for 15 minutes yesterday; today doesn’t want to run…. What’* going on with it? 46 psi fuel pressure on the fuel rail. Any suggestions? Similar experience and solutions you use to get on the road?

Could be several things, definitely not the throttle body.

- IAC?
- Plugged cat?
- Plugged air filter

How many miles on it?

How many miles have you owned it?

Any recent repairs before the problem started?

Low fuel pressure. Specs are 48 to 55. We like to see a minimum of 50. Even at that you can have problems with some if these. They are finicky at the minimum.

first off, thanks for the responses.

could it be bad gas somehow? Is there a way to fuel the rail with enough pressure from an external source?

How do I get a diagram or the throttle linkage itself; the return spring replacement chiefly.?.
How do I reset the security feature. In case it’* a security shutoff.

You need to fix the low pressure problem before trying to find other problems.
