I would like to thank everyone for helping me. I finally have it fixed, it was the fuel pump. Replaced it and the sending unit and it runs fine. I really appreciate the help.

Ok I can anyone tell me where the fuel pump ecu is located on a 92 lexus ls?

I tested the wires. The ones going to the fuel pump isn't getting any power. What could cause this?

Okay the fuel pressure regulator is fine. The fuel pump isn't getting any power. Someone had straight wired the sending unit (that green wire from the sending unit to the radio in the above pictures). Where do I go from here? What will cause the fuel pump to not get any power?

Ok I will try that. I got off work too late today. Tomorrow will be an early day. I hope that works.

After trying all morning I was finally able to pull trouble codes. The only one I get is #24. IAT Sensor signal. Can anyone tell me where it's located?

I guess the feul pump wasn't getting any power. I pulled the cover off the fuel pump and this is what I seen. Any help would be appreciated.

Ok, Here is where I am now. I took the MAF/AFM off and sprayed starting fluid into the throttle body and the car cranks and runs as long as I spray the starting fluid. Does that mean it's a fuel related problem? How do I check the Fuel Pressure Regulator? Where is the fuel pressure regulator?

OK I'm sorry I wasn't clear before. It does not catch at all. It tries but never catches. I noticed the plug that plugs into the MAF/AFM is real loose. I tried pushing it and holding it in place while my wife tries to crank the car, it made the starter turn faster but it still didn't catch...

Hi Everyone I'm new to Lextreme. Can someone please help me figure this out? My car will turn over but will not catch. When I try to crank it, it will turn like it wants to catch but then dies after about 4 or 5 tries.
