Question about Cars & Trucks
You need to find out if the fuel pump is working, getting gas up to the engine.
If the pump is working and seen to have good fuel pressure, check ignition by checking for spark.. To work, the engine needs, you know, gas, air, spark, and compression. Why people say, check for gas, check for spark.

Did you have the new starter tested befor you installed it? Was their a lot of corosion on the battery cables? The cables might be corroded as well cousing too much resistance for the starter to crank.

Ignition relay or fuse could be the problem. When you turn the key to start do you hear a fuel pump kicking on and or do you have spark when you hot wire the starter (I know it's hard to check while trying to start it)? You can email me back and I might be able to pinpoint it more.

SOURCE: Hello. My 1997 Chevy Tahoe
Now you have a good battery & a starter that turns over the motor
Have you cycled the key on & off with a fuel pressure gauge on the
Do you have a fuel filter that isn't over 3 or 4 years old?
Have you checked for spark while cranking ? Use an old plug on the wires,
if you have ignition wires,don't ground the wire without resistance
If you removed the ducting & MAF Sensor it won't start
Tell us what you checked & exactly how that was done.

Check the dash once you turn the key to the run position the passlock runs a security check using a set resistance value through the chip in the key. If the security light begins to flash the reading it received was incorrect or it didn't get a reading at all. You can try reseting the value it is looking for by turning the key to start then releasing it. After 10 minutes turn it off then cycle it start again leaving it in on for 10 minutes then back to off then one more time. After the third cycle has completed for a total of 30 minutes. You should be able to turn the key on and start the vehicle. If the light continues to flash their is a problem with the chip in the key or the connections within the ignition its self. Both are common but a Pass Lock Relearn as described above will usually adapt to the poor connection values. Hope this helps.
