I have a 1999 Chevy suburban. Fuel pump was replaced also replaced computer. When you turn on the key no lights come on (check engine and all) will turn over but won't start

SOURCE: 1999 Continental will not start

Does anti-theft light come on for a sec then turn off when you turn on the key or does it flash with key on?
You said that CEL turns off while cranking,does it come back on if you continue to crank after about 8-10 seconds of cranking?
If it does not then your PCM is not seeing a signal from the crankshaft postion sensor.You can try wiggling the harness at the crankshaft postion sensor and see if it will start.

I had the same problem with my 99 suburban. There was a memo sent out by GM to all of the service shops that tell them when you replace the fuel pump or just desconnect it you need to replace the pigtail wiring harness that connects to the pump or it will burn up the new pump. I went through 3 pumps before I found this out after I replace the pigtail it fixed the problem.

It sounds like you have a security problem, I had the same thing it would fire and run for half of a second and then that was it if anything at all. Had the security system rebooted, now it starts and runs fine.

Could be one of several items...I'd check the fuel pump relay, auto shutdown relay and the ignition switch itself. I'd bet on it being one of those relays but, we all have been fooled at least once!!! I'd also make sure that body and engine grounding is good and clean. Relays can't work properly without a good ground.

There is a fuse that deals with the fuel pump circuit through the ECM. If you haven't checked it's in the fuse panel under the hood in the engine compartment on the drivers side by the brake master cylinder. I hope that you have a cover for it with the names of the fuses. The fuse you want to check will be the fuse marked "ECM B". I gave you a picture of the fuse layout but it's not a good one but I did put an arrow to the one I think it is. I pretty sure that's the one but not 100 percent because it's pretty blurry. In any case there is a fuse marked "ECM B". I would check there if you haven't already. Other than that You may have to check your wiring. There is a fuseable link at the starter you may want to check if that fuse isn't blown. I hope this helps and good luck.
