2000 Maxima not starting after starter install

My neighbor just replaced the starter on his 2000 Maxima. Fairly simple job, but vehicle will not turn over now. Cranks better than it ever has, but that is it. He feels it may be due to security. Any thoughts?

To run, engine wants:
1. gas/injection,
2. spark,
3. some pressurized air (cranking etc).
4. all 1-3 properly timed by ECU & mechanics
One of the 1-4 is missin... which one?
First Aid Diag:
1a. fuel pump sound and stiffenin fuel hose means pressure is there, gas will be stinkin around if nostart cranking goes on... 1b. injectors do click when control signals from ECU do 'arrive' (listen, screwdriver on injector, ear on handle - precondition: crank sensor has to rotate, ECU be 'alive')
2. plugs do spark when spark is present: add a spare grounded plug on coil pulled up - take a peek while cranking
3. Tst the air 'travel': plastic bag will be puffed up while cranking (=timing is ok) when placed on exhaust pipe end. If it is sucked, cam chains have jumped (very rare).
4. This needs some tools...
I'd first try to look around for cut/missing/disconnected/loose wirings/groundings/vacuum hoses.

Ok--here's where we are at so far.
Car continues to crank just fine. Have reset security to key. Every time battery is connected, ECU2 fuse blows. Nothing other than installing a new starter has occurred.

Not connected with security.
Open all connectors in that circuit, find wassup via 'Favorite Links', clic below. Fuse blows? If no, start connectin until your neighbor problem is found. (fried ? ECU due to heater coolant leak?)

Neighbor had his car towed to the mechanic yesterday and turns out he somehow pinched some wiring while pushing the starter into position. Apparently, starter is fried as well.

Did he pinch a positive wire when he put the starter on? Not suprized he killed his new starter. I remember when I took mine out for inspection that there were wires all over the place that you had to move.

That's exactly what he did. Guess he didn't feel that all those wires were important.
